Saving watermelon seed, rainy day reading, Heritage Harvest Festival

Scooping watermelon seed.

I wrote recently about saving tomato seed, and here I’ll write about extracting watermelon seed. We grow Crimson Sweet Virginia Select, which we sell to Southern Exposure Seed Exchange. I walk through the patch with a grease pencil (china marker) in July when the melons are forming and write numbers on 40 nice-looking big melons. I’m selecting for earliness, size, disease resistance and flavor.

Once the melons start to ripen, I go out to the plot once a week with my trusty garden cart and a collection of clean buckets, a notebook and pen, a big knife, a large slotted spoon, a couple of damp rags, a bottle of water and a big straw hat. I start testing the numbered ones for ripeness. If they are ripe I decide if they are seed-worthy, demoting any with dead vines (not disease-resistant!) or too small. I find promising replacements for any I decide not to save seed from, and number those.

When I have a good one, I cut it in half and scoop the heart out into a very clean bucket. I taste a piece (that’s the “good flavor” test). These days they all seem to taste good, but the first few years of seed selection, I had some I didn’t like much, so I didn’t save seed from those. See the first photo for the scooping task. Once the heart is scooped out, there is a layer of flesh with seeds in, which I scoop out into a moderately clean bucket. Then a layer of flesh without seeds for the food bucket.

In the blue bucket is my “dry zone” with my notebook. I write down which melons I harvested, any I discarded, any new ones I added, and how many are left to find in the coming weeks. Generally I harvest 7-10 watermelons per week, generating two buckets of fruit and two half-buckets of seeds. The watermelon seeds are fermented for four or five days, then washed – just like processing tomato seeds I wrote about last week.

I harvest 5 or 6 times, from Late July to early September. I don’t want to be selecting for late-ripening melons so I stop harvesting seed long before the fruits are over.


My most recent blog post for Mother Earth News is about repairing garden hoses, most of which you already read about here. It’s in the DIY blog this time (most of my posts go in the Organic Gardening blog). I just heard some numbers for how various of my Mother Earth News blogposts this year are doing, and the big favorite topic is Growing Lettuce Year Round: Succession Planting for a Continuous Supply: 10,924 views! Growing Winter Lettuce: 4,620 views, is second favorite. people sure do love lettuce! Other popular topics this year have been Winter Hoop House Harvest Schedule, Using Open Flats (Seed Trays) to Grow Sturdy Seedlings EasilyHeat-Tolerant Eggplant Varieties, and Planting Leeks.

When I look to see which posts on this blog people visit most often, I see that garlic harvesting and garlic scapes are very popular, as are posts about sweet potatoes.


Sometimes I post links to my slideshows, but here’s a You Tube I’ve been meaning to tell you about. This is my presentation of Succession Planting for Continuous Vegetable Harvests at New Country Organics.


The September Growing for Market is out. The cover article, by Carolina Lees, advocating a Farmer Retreat. This is a wintertime regional gathering of farmers, with scheduled time for discussion and also for casual hanging-out. No imported speakers! The author is in Oregon, and envy-inducing photos of the beach-side retreat are included. But, what a good idea!

David Ross writes about grower relationships with wholesalers. Shawn Jadrnicek, author of The Bio-Integrated Farm: A Reveolutionary Permaculture-Based System . . .  writes about mulching and crimping techniques for no-till vegetables, including how to have weed-free cover crops, and get the right machinery to roll and crimp them. he uses a manure spreader to spread tree leaf mulch, and shows photos of a very tidy farm.

Rowan Steele writes about obtaining used silage tarps (as advocated by Jean-Martin Fortier) for covering beds to control weeds organically. Rowan writes about how to use the tarps and suggests coordinating a used silage tarp delivery for your small farm community. Contact Travis Quirk at the nonprofit Simply Agriculture Solutions Inc. in Saskatoon, Saskatchewan ([email protected]).  The tarps may be delivered for the cost of shipping. Canadian farmers are required to recycle their “grain bags”, but it’s hard for them to find a recycling facility in Canada, so the plastics are sent to the US. They are happy to be able to divert the material for a second use. Sounds great to me!

Jane Tanner writes about William’s WIldflowers, a floral design business run by two sisters, using lots of native flowers, especially perennials, for weddings and other formal occasions.


See you at the Heritage Harvest Festival on Friday September 8 (my premium workshop on growing sweet potatoes from start to finish) or Saturday (strolling around). Last time I looked there were still tickets available for my workshop ($20)

Heritage Harvest Festival

Asian Greens Slide Show, Crops in our Hoophouse

I’ve started my year of monthly posts about Asian greens with one about senposai and at the Mother Earth News Fair in Vermont this past weekend, I presented my slide show on Asian Greens, which is here for those who missed it. Click the diagonal arrow symbol to get the full screen version.

Today, back on the farm, I spent the morning in the hoophouse. I harvested 4 buckets of cucumbers from one 90′ bed of Spacemaster bush cucumbers. We harvested 2 buckets two days ago, and today they have really taken off!

I also harvested 3 gallons of green beans – we planted Strike, a very upright variety. We find that bush beans tend to sprawl in the hoophouse, and the varieties that do well for us outside (Provider and Bush Blue Lake, from Fedco Seeds), grow straggly inside and the beans curve. It’s probably because the shadecloth on the hoophouse is too dark for beans.

The Gentry yellow squash are doing very well. I’ll harvest those tomorrow (we’re alternating cucumber and squash harvest days currently)

The other crops in our hoophouse now are peppers (we’ve had a handful of green bells). two beds of tomatoes that have been struggling with aphids and sooty mold, and some Iron and Clay cowpeas as cover crops. See this sad picture of the aphids and sooty mold:

Aphids excrete a sweet liquid called honeydew. In warm moist conditions this sugary substance grows a black mold on every deposit. This is called sooty mold. We have been dealing with it by jet-washing some of the tomatoes every sunny day, and we are winning. The photo above was specially chosen to demonstrate the problem – it’s not a crop to be proud of at this point! We use a brass jet-spray nozzle on a hose and wash them in the middle of the day, so the leaves can dry quickly – we don’t want any more fungal tomato diseases moving in!

Garlic scapes, upcoming events, hoophouse seed crops

I always know when garlic growers in slightly warmer or more southern climates are starting to find scapes (the edible firm flower stems of hardneck garlic) because my posts about scapes suddenly become popular! My posts “Garlic scapes! Three weeks to bulb harvest,”  and “Garlic scapes to cheer us up” have been reread a lot recently, and Harvesting garlic is due for attention any time now. My Growing Great Garlic slideshow is here. Click the diagonal arrows to view it full screen.

And sure enough, our own scapes are ready too, even though this is a week earlier than usual.We harvest two or three times a week until there are no more. I love garlic scapes as one of the first outdoor crops of the spring, and a flavor different from leafy greens and stored roots, the staples of early spring.

Our tulip poplars are flowering now too, also early. Our average date for those is 5/1, and we’re a few days ahead of that. When I was a beekeeper it was important to be ready for the tulip poplar flowers, because that was our big nectar flow of the year, and I had to dash out to the beeyard and stack up 5 supers on each hive. I had to give up on the beekeeping because the combination of lifting heavy boxes and twisting was hurting my back too much. Oh, and those heavy boxes were full of thousands of stinging insects, but I didn’t mind that bit as much. The flowering of tulip poplars and the germination of ragweed are both phenology signs that signify that the Growing Degree Days have reached 200 (on a base of 50F) and that conditions are warm enough to sow sweet corn. Myself, I watch the young leaves on the white oaks and when they are the size of a squirrel’s ear, I decide it’s warm enough for corn.


This weekend I will be at the Mother Earth News Fair in Asheville, NC. Click the link to see the location, the workshop schedule and the list of vendors who’ll be there. I’m presenting two workshops, Growing Sweet Potatoes from Start to Finish on Saturday 5/6 at 12.30on the Yanmar Sustainable Agriculture Stage, followed by book-signing and chatting at the Mother Earth News Bookstore; and Succession Planting for Continuous Vegetable Harvests on Sunday 5/7 at the Heirloom Gardener Stage.

Of course, you’ll need to be there and  hear me speak to get the most out of it. I’m also doing short demonstrations of How to String Weave Tomatoes at booth 2800, New Society Publishers (near the Bookstore) on Saturday at 10 am, 11 am and 5 pm, and on Sunday at 10 am and 11 am. They’re half-hour time slots. My table top demo kit uses #2 pencils and pink tinsel.

The May issue of Growing for Market magazine is out, including my article about growing seed crops in hoophouses. I interviewed Clif Slade, founder of the 43560 Project at Virginia State University, about several creative sequences of food crops and seed crops he has grown in a high tunnel. (Collards, okra) as well as plant starts (sweet potatoes, onions). He farms in Surry County, Virginia.

Also in this GfM, Simon Huntley of Small Farm Central encourages small farmers to set aside two hours a week for a quick and efficient bit of online marketing “One Photo,
One Paragraph”. His goal is to help farmers stay in the spotlight with their products, without having to spend a great deal of time on it in the busy season.

Conor Crickmore has an article about preparing and laying out no-till permanent raised beds very precisely in a hoophouse. He uses the Quick Cut Greens Harvester to mow off over-size baby salad crops to clear the bed prior to broadforking and adding needed soil amendments.

Spencer Nietmann writes about what it really costs to start a farm. Jesse Frost discusses various types of plastic to cover hoophouses  (high tunnels), and lastly, Jane Tanner writes about native perennials for flower farms

Growing for Market, Sweet potato propagation and yields

The April issue of Growing for Market is out! For those of you growing sweet potatoes, Andrew Schwerin from NW Arkansas has written an interesting article. I’ve written about starting sweet potato slips before and I have a slideshow that includes three methods of  starting your own slips.  He and his wife Madeleine grow 1500 feet of sweet potatoes each year, a third of their growing area.

I was interested to note their reasons for growing so many sweet potatoes (apart from the obvious fact that they can sell that many). Sweet potatoes are not a big moneymaker in terms of the space occupied. Here at Twin Oaks we pondered similar issues this winter when deciding which crops to grow.  We worked down a list of 25 factors, deciding which were important to use. We chose our top handful of factors and then worked down a list of crops we might grow, awarding points (or not!) for each factor for each crop. This helped us narrow down what to focus on this year. And yes, we are growing sweet potatoes! I wrote about this in Growing for Market in February 2017.

These growers listed the following factors as their reasons to grow sweet potatoes:

  • Sweet potatoes produce well in our soil

  • They aren’t troubled by intense summer heat

  • Extensive vines will smother most weeds

  • Few pest or disease issues

  • Most of the labor is in early October, between intensive harvests of summer and fall crops

  • They store long-term for steady sales through the winter

They like Beauregard, and wanted to try using the single node cutting method, as advocated by Anthony and Caroline Boutard – see my Sweet Potato slideshow for details. Initially they were excited about the single node cutting process, as their roots produced exponentially more growing shoots each week. OK, maybe exponential is a bit of an exaggeration, but it gives the sense of it. Because they had so much propagation material, they started making 5-node slips, rooting clusters of cuttings in pots of compost, 3 nodes in the soil for roots, 2 nodes above ground.

Some of their single node cuttings failed to thrive, both in the trays and in the field, so they developed a 2-node cutting system instead, and also used their five-node slips. And so they had a trial of three sweet potato cutting methods, with plants in different 100 ft beds. In the past (using the regular slips method) they have averaged yields of 500-600 lbs of sweet potatoes per 100 ft bed, with a range from a poor 250 lbs to a few successes with 1000 lbs/bed. Of course, yield is not the only important feature of a market crop, although understandably it has a high profile for those growing 1500 row feet for sale.

At harvest, they found that their single-node sweet potato plants were producing a couple of hundred pounds per 100 ft bed. The 2-node beds produced about 500 pounds per bed, of relatively few, very large (6 – 20 lb) sweet potatoes. The plants with 3+ nodes in the soil gave more reasonable sized potatoes. They tend to get jumbos, so they have started planting closer (10″) to tackle this – not many customers want jumbos.

In his article in Growing for Market,  Anthony Boutard pointed out that single-node cuttings do produce fewer tubers which are larger and better formed. This is a big advantage for growers in the north, but less so in the south. The Arkansas growers have found that the 2-node cuttings are even better at this tendency in their location, which is much further south than Anthony Boutard’s farm.

Other articles in this month’s Growing for Market include Managing a cash crisis
How to climb out of the hole by Julia Shanks, the author of The Farmer’s
Office. Farmers deal with a very seasonal cash flow, and may well have gone into farming with good farming skills but not good business skills. Julia writes about four rules for getting out of a financial hole.

  1. Quit digging (don’t incur any more inessential expenses).
  2. Keep the dogs at bay (communicate with your creditors about how you plan to pay, and how you plan to keep producing the goods).
  3. Climb out (increase revenue in as many ways as possible).
  4. Get your head out of the sand (don’t panic, face realities, be proactive).

She goes on to list 10 ways to protect yourself from getting in such a hole again.

Sam Hitchcock Tilton has an article about cultivating with walk-behind tractors, ie, weeding and hoeing with special attachments. There are some amazing walk-behind
weeding machines (manufactured and homemade) throughout the world. There
is an entire style of vegetable farming and scale of tools that have been forgotten, in between tractor work and hand growing – the scale of the walk-behind tractor. The author explains how commercially available tools can be adapted to work with a BCS or a carefully used antique walk-behind tractor.

Mike Appel and Emily Oakley contributed Every farm is unique, define success your own way. Money is not the only measure. Quality of life, family time, and personal well-being are up there too, as are wider community achievements. Farming is equal parts job and lifestyle, and the authors recommend having a strategic plan for yourself and the farm, which you update every couple of years to pinpoint goals and the steps you need to take to reach them.

Liz Martin writes about husk cherries (ground cherries) and how to improve production of them, to make a commercial crop viable. Who would have guessed that hillling the beds before planting can make harvest so much easier, because the fruits roll down the sides?

Judson Reid and Cordelia Machanoff wrotea short piece: Fertility tips and foliar testing to maximize high tunnel crops, and Gretel Adams wrote about  Scaling up the flower farm. Many of the ideas also apply to vegetable farms.

Mother Earth News post, Organic Broadcaster, Jamaica trip

I wrote a blog post for the Mother Earth News Organic Gardening blog on Hoophouse Intercropping in Spring.

We transplant our tomatoes, peppers, squash and cucumbers into the middles of the beds of winter crops. We pull out the middle rows, dig holes, add compost and transplant. Initially the rows of winter greens to the south of the new plants shade and shelter them a little, which helps them settle in. The next week we harvest out the greens on the south side of the new crops, then after that (but less urgently) the row on the north side.

3/15 is our usual tomato planting date, 4/1 we planted squash. 4/5 we’ll put the cucumbers in and 4/7 the peppers. We used to plant the hoophouse peppers earlier but it’s such a struggle keeping them warm enough as seedlings in the greenhouse, that we moved a week later. It’s just not worth having stunted pepper plants!


The March/April Organic Broadcaster is out too. Phew it’s hard to find enough reading time in spring! There are articles about the Organic check-off program (discussed at the MOSES Conference), information about policy work for the National Organic Program, and their “Ask a Specialist” column answering a question about “fast, inexpensive greenhouse space.” The answer was souped-up 10 x 60 ft caterpillar tunnels, including heated benches for starting plants. Other articles address organic grain production, humane mobile houses for poultry, a profile of the MOSES Farmers of the Year, Hans and Katie Bishop, solar panels on small farms, diverse meat CSA farms, as well as news from the conference. Something for everyone!


I’m volunteering with the Jamaica Sustainable Farm Enterprise Project. Here’s a bit more about the project:

The people of Jamaica and the greater Caribbean region have long been buffeted by  natural and human-caused disasters that have left them in a state of economic, social, and environmental crisis. Jamaican  people are vulnerable due to national dependency on unaffordable, less healthy, imported food, lost skill sets needed to produce certain crops without expensive chemical inputs, and natural disasters that wipe out farmers crops with regularity. The Parish of St. Thomas and the other eastern parish of Portland have systemically been the most forgotten and underdeveloped parishes in Jamaica for over a century.

St. Thomas is a farming parish. However, since the liberalization of the banana industry by the European Union and NAFTA all the banana plantations have closed leaving few agricultural avenues for profitable employment in the parish. Many of the people of St. Thomas still rely on small cash crops and seasonal tree crop production for their livelihood.

JSFEP aims to focus on local sustainable production to increase food security and help develop high value internal and export markets to increase agricultural profitability. Permaculture and organic (POF) systems provide solid foundations for these solutions.

I’ll be going to St Thomas parish (click for a map) from 5/11 to 5/22, providing training in vegetable crop planning. JSFEP partners The Source Farm, a multi-cultural, intergenerational eco-village, located in Johns Town, in the parish of St. Thomas.  You can see a slideshow at their website. And You Tube has a short video The Source Farm Foundation Ecovillage.

Well, I’m out of time this week, as I need to get my laundry off the line and spray the aphids in the greenhouse and hoophouse with soapy water.

Hoophouse slideshow, Ruminant podcast, potatoes planted

Here’s my updated Spring and Summer Hoophouse slideshow, that I promised all the people at my Organic Growers School workshops. I rearranged the slides in what I think is a better order and revised the resources section.


The Farmers Aren’t All Right.
Podcast from the Ruminant

I also took part in an interview with Jordan Marr for a podcast with The Ruminant: Audio Candy for Farmers, Gardeners and Food Lovers. It’s about farmers’ struggles with mental health problems, trying to cope with the many and varied stresses, while the public wants farmers to appear competent and blissful with all that time in the Inspiring and Nurturing Outdoors.

“Farming is tough work. The unpredictability of the job and the pressure to present a curated, bucolic version of the work can easily lead to various kinds of mental health problems: despair, feeling overwhelmed or like a failure, or even depression. In this episode, co-produced with Jessica Gale of Sweet Gale Gardens, we discuss the prevalence of mental health problems among farmers, and how to address them.” Jordan Marr

As well as Jessica Gale, the episode includes discussion of Professor Andria Jones-Bitton’s work and interviews with Jean-Martin Fortier of The Market Gardener and Curtis Stone of The Urban Farmer.


The March issue of Growing for Market is out. Nothing from me this month (I have articles for May and June/July coming up). In this issue. There are articles about No-till vegetable farming (Conor Crickmore at Neversink Farm, in the Catskill Mountains of New York), and Bio-integrated farm design by Shawn Jadrnicek, co-author with Stephanie Jadrnicek, of The Bio-Integrated Farm: A Revolutionary Permaculture-Based System Using Greenhouses, Ponds, Compost Piles, Aquaponics, Chickens and More. Lots of water in this book, and very practical. There’s an article on A DIY mobile cooler for moving and storing perishable foods  – an insulated trailer using Cool-Bot technology by Cary Rivard, Kansas State Research & Extension Horticulture & Forestry & Extension Vegetable & Fruit Crop Specialist. Karin Tifft has written The “other” reasons to grow in a greenhouse: climate, light, good use of space, reduced wastage of produce, energy conservation and more. Andrew Mefferd, the editor has written on growing cucumbers umbrella style under cover. Finally, Debra Prinzing writes on Making your mark with local branding.

Hoophouse seasonal transition to tomatoes, peppers, squash, cucumbers

This past weekend I was at the Organic Growers School spring conference in Asheville, NC. I presented my workshop on Spring and Summer Hoophouses twice. This link will take you to a blog post where you can get the handout. An older version of the slideshow is at this SlideShare link. Later this week I will tweak the presentation a little and upload the revised version. It wasn’t very spring-like in Asheville. We got 3″ snow, but gardeners and farmers are a hardy lot, and attendance was still good. My workshops were packed (the room was quite small).

Now I’m home and we had snow in the forecast for Monday night, but got ice pellets instead. The worst of the weather passed us by. It’s still very cold though, and so we are delaying transplanting our early tomatoes in our hoophouse, which we had scheduled for 3/15 and 3/16. The photo above shows where we’re headed: sturdy transplants in the middle of the bed, with wire hoops to hold rowcover on cold nights. Here’s where we are now:

March hoophouse bed prepared for tomato planting.

When we make the transition from hoophouse winter crops to early spring crops, we don’t clear the whole bed. First we harvest out the greens down the middle of the bed, then measure and dig holes every two feet and put a shovelful of compost in each hole. Within a couple of weeks after transplanting the tomatoes, we harvest the greens on the south side of the bed, as they will block light from the new crop. After that we harvest the greens on the north side. This allows us to keep the greens later, which covers the time (the Hungry Gap) until the new spring plantings of outdoor greens start to produce.

Meanwhile the tomato transplants are in pots in our greenhouse, where we can keep them warmer at night with rowcover. Our greenhouse stays warmer at night than our double-poly hoophouse. It has a solid north wall and double-pane glass windows (old patio doors).

We use the same method for our peppers, cucumbers and yellow squash, transplanted 4/1. In the photo below you can see the winter crop of Bulls Blood beets, which we grow for leaves for salad mixes, discarded beet stems, young squash plants and one of the wire hoops that hold rowcover on freezing nights.

In the hoophouse we have three crop seasons:

  1. winter crops planted in the fall, harvested November to April (some spinach to May)
  2. early warm weather crops planted in March and April, harvested June and July (peppers to November)
  3. high summer crops planted in July and harvested August to October.

 

Lettuce in February, Growing for Market, open seed flats

Baby lettuce mix in our winter hoophouse.

We still have plenty of lettuce to eat, although our first sowing of baby lettuce mix in the hoophouse has come to its bitter end, and the second sowing isn’t quite ready (I think we sowed it a bit later than intended). We are still harvesting leaves from the large lettuce we transplanted in October.  Soon we’ll have the second and third baby lettuce mix sowings to bring a welcome change. We are about ready to transplant our first outdoor lettuce, to feed us mid-late April.

Here is a month-by-month planting and harvesting narrative for our hoophouse lettuce in Zone 7, from September to April:

September: Sow cold-hardy varieties in the second and third weeks (outdoors or in your greenhouse) to transplant into the hoophouse at 4 weeks old .

October: 4 weeks after sowing, transplant those lettuces at 8” spacing to harvest leaves from mid-November to early March, rather than heads. In late October, sow the first baby lettuce mix, for up to 8 cuts from early December to late February, and sow a small patch of “filler lettuces” to replace casualties in the main plantings up until the end of December.

November: 11/9 sow more filler lettuce, to be planted out in the hoophouse during January. Transplant the first “filler lettuce” to replace casualties. Harvest leaves from the transplanted lettuce.

December: Use the “filler lettuce #1” to replace casualties or fill other hoophouse space, for lettuce leaves in January and February, or heads in February. At the end of December, make a second sowing of baby lettuce mix, to harvest from late February to the end of March. Harvest leaves from the transplanted lettuce, and cut the first baby lettuce mix.

January: Use the “filler lettuce #2” to fill gaps in the lettuce beds up until January 25. After that is too late here for hoophouse lettuce planting, and we use spinach to fill all the gaps, regardless of the surrounding crop. Harvest leaves from the transplanted lettuce, and cut the first baby lettuce mix whenever it reaches the right size.

February: 2/1 sow the third baby lettuce mix, to provide up to three cuts, from mid-March to late April. In mid-February, consider a fourth sowing of baby lettuce mix, if outdoor conditions look likely to delay outdoor harvests. Harvest leaves from the transplanted lettuce, and cut the second baby lettuce mix when it sizes up. Harvest the first baby lettuce mix, clearing it at the end of February before it gets bitter.

March: Harvest leaves from the transplanted lettuce, and cut the second baby lettuce mix whenever it reaches size. Cut the third baby lettuce mix when it sizes up.

April: In the first half of the month, harvest the last of the transplanted lettuce as heads . Continue to cut the third baby lettuce mix until it gets bitter. Cut the fourth baby lettuce mix when it sizes up. Outdoor lettuce heads are usually ready for harvest mid-April. Plan to have enough hoophouse harvests until the outdoor harvests can take over.

The February issue of Growing for Market is out, including my article How to decide which crops to grow which I previewed some of here last August. I also included some of the material in my slideshow Diversify Your Vegetable Crops. Click the link to see the slideshow. This past winter we used this kind of process to reduce the amount of garden work for 2017. I’m retiring from garden management and the new managers  want to stay sane and not be exhausted all the time. We have fewer workers this year (the past few years actually), so we needed to slim down the garden and not go crazy trying to do everything we’ve done in the past. I’ll still be working in the hoophouse, the greenhouse, and doing some outdoor work, as well as being available to answer questions and provide some training when asked.

Back to Growing for Market. There’s a great article for new small-scale growers, from Katherine Cresswell in northern Idaho, Year One Decision Making, about starting a farm with only one implement. Careful planning lead Katherine and her partner Spencer to focus on fall, winter and spring vegetables, as no-one else around them provided these, and they had experience of winter growing from working on other farms. Clearly a high tunnel (hoophouse) needed to be in the plan. It was essential that they hit the ground running and have saleable produce within six months. The expense budget was very tight. They bought a BCS 739 walk-behind tractor (which they both had experience of) and a rotary plow. A very down-to-earth article to encourage any new grower with limited means.

There are reviews of three new books by GfM writers: Compact Farms by Josh Volk, Floret Farm’s Cut Flower Garden and The Greenhouse and Hoophouse Growers Handbook by Andrew Mefferd, the editor of GfM. Brett Grohsgal has written a valuable article about his 15 years experience with on-farm breeding of winter-hardy vegetables, both in the field and under protection of hoophouses. Informative and inspiring. Erin Benzakein has written about rudbeckias, the unsung heroes of summer bouquets, and Gretel Adams has written on new flower varieties to try in 2017.


I have a new post on the Mother Earth News Organic Gardening blog, Using Open Flats (Seed Trays) to Grow Sturdy Seedlings Easily – How to make reusable wood flats (seed trays) for seedlings, and use them to grow sturdy vegetable starts to transplant into your garden. This is a way to avoid contributing to the problem of agricultural plastic trash and be self-reliant in gardening equipment. You can also grow stronger plants by giving them a larger compost volume than plug flats or cell packs provide.

I heard that my MEN blogpost Green Potato Myths and 10 Steps to Safe Potato Eating was very popular in January, coming sixth in their table of most-viewed posts on all topics. This has been out there in the blog-iverse for almost 18 months, so clearly there is a lot of concern about eating healthy food and not wasting what we’ve grown.

The false spring has been barreling along. Last week I reported that we’ve seen a flowering crocus (2/17). Since then, we’ve seen daffodils and dandelions flowering, heard spring peppers and already the maple is flowering (2/25). These are all markers on our phenology list. The maple flowers on average 3/12, with a range (before this year) of 2/28 in 2012 to 4/2 in 2014. A 9-year record broken!

Storage Vegetables slide show, Diversify your vegetable crops slideshow again

Well, we are getting back on the horse/bicycle after being hacked, and hoping to return to normal. Here is my other presentation from the SSAWG conference: Storage Vegetables for Off-Season Sales.

And in case you missed last week’s post before it got attacked, here’s Diversify Your Vegetable Crops again:

The three presentations I gave this past weekend at the PASA Conference can be found at SlideShare. Click the link to get directly to the first of the pages with my presentations on it, or go to the SlideShare site and put my name or that of the presentation you want in the search box. I presented Growing Sweet Potatoes from Start to Finish, Crop Rotations for Vegetables and Cover Crops and Succession Planting for Continuous Vegetable Harvests


Dealing with the hack has taken a lot of time and energy, so this post will be short. Today has been unseasonably warm, and atypically windy. We have been pruning blueberries, preparing raised beds and harvesting spinach, leeks and garlic scallions, our first “new” crop of 2017. Usually I reckon on starting to harvest these March 1st, but they have grown a lot recently. They are about 6″ tall. A very flavorful fresh taste for this time of year (the Hungry Gap) when we mostly get leafy greens and stored roots.

Simply set aside all the tiny garlic cloves when you do your main planting, prepare a series of furrows close together. Tumble in the cloves, shoulder to shoulder, any way up. Cover the furrows, mulch over the soil and wait for early spring. When the garlic scallions are at least 6″ tall, start digging them up. Use them raw if you are inclined, or chop and cook them in omelets, stir-fries, soups, anywhere you’d like the taste of garlic. Pow!
