No-Till Growers and Josh Sattin collaborated to post this Hoophouse Tips video interview of me talking about our hoophouse:
After a Best Ever day on November 7, 2019, when 876 people viewed my website (4,855 that week), December has been quiet. It’s not a big gardening month for most of us, and the month is full of holidays. And then there’s the urge to hibernate.
Nonetheless, I have been reliably posting every week, and you might have accidentally missed something, while entertaining the visiting aunts and uncles, or rushing to get the carrots harvested, or something involving food and drink. Here’s a chance to find the lost treasures!
Soil Tests and High Phosphorus Levels close behind at 9,503. High phosphorus is a worry for organic growers, especially those using lots of compost, as it can build up each year.
How to Deal with Green Potatoes at 8,613, with sustained interest through August, September and November. Obviously we are not the only growers with this problem, caused by light getting to the tubers.
We drove home seven hours from the Pennsylvania Mother Earth News Fair yesterday through the rain. The remnants of Hurricane Florence. We were among the lucky people. Earlier forecasts for Florence had the hurricane raging across central Virginia.
At the Fair, I gave two workshops: Fall and Winter Hoophouses and my new Lettuce Year Round, which you can view right here. Click the diagonal arrows icon to get a full screen view.
I’ve updated my Events page again, now that the September- April “Events Season” has hotted up. I’ve added in a couple of new ones and updated some others. Click the Events tab to find conferences and fairs near you, and be sure to come and introduce yourself!
I’m giving a Premium Workshop on Friday Sept 21, 3-4 pm Classroom 7. Click the link HEREto book for that.
Feeding the Soil
In this workshop I will introduce ways to grow and maintain healthy soils: how to develop a permanent crop rotation in seven steps, and why your soil will benefit from this; how to choose appropriate cover crops; how to make compost and how to benefit from using organic mulches to feed the soil. Handouts.
Book-signing Friday 4.15 – 4.45 pm.
On Saturday there are events all day from 10am to 5pm. $26 general admission.
This is the first of a new monthly series of blog-posts on Alliums for the Month, which, like my previous series on lettuce and Asian greens, I plan to run for a year. Alliums are the onion family. With this series, I’m going to talk about which alliums to harvest each month, which to plant, and which need other kinds of attention.
I haven’t thought of any alliums to plant in May (at least, not here in central Virginia), but there’s plenty to harvest, and don’t forget to weed! Because alliums don’t have big spreading leaves, they are not good at shading out weeds, so we have to take care of the weeds for them! Particularly bulb onions and garlic this month, as they are only a few weeks away from harvest and will benefit from removing weeds and mulch to let in fresh air to help the bulbs dry down (rather than get fungal diseases!)
Harvesting garlic scapes
Starting any day now, we will begin harvesting garlic scapes (the firm, edible flower stems of hardneck garlic). My previous posts about scapes are some of my most popular ones.
See last year’s Garlic scapes, upcoming events, hoophouse seed crops, posted on May 2, 2017. There I noted that in 2017, scapes came early, as did Tulip Poplar flowers, at the end of April. We harvest scapes two or three times a week for about three weeks, until no more appear. Garlic scapes are one of the first outdoor crops of the year, apart from rhubarb and asparagus, and their flavor is refreshingly different from leafy greens (the staple hoophouse crops of early spring) and stored winter roots.
I posted Garlic scapes! Three weeks to bulb harvest on May 11, 2015. That year scapes were later than average. This post is a very popular one, and I’m still wondering if I was over-confident in predicting 3 weeks to bulb harvest everywhere in the US! Please do leave a comment if you have records for how long you get between scapes and garlic bulb harvest.
I’ve done some research into what triggers flowering in garlic, but haven’t found much solid info yet. In general, plant flowering is triggered by some combination of enough vernalization (chilling hours during the winter and early spring – maybe 10 weeks below 40F), plant maturity, temperature and photo-period (the relative length of day and night). In cold weather the plants suppress the flowering signal. The leaves perceive the amount of daylight, and when the temperature is also right, they trigger flowering by sending a signal (called Florigen) to the shoot tips. Florigen may be an actual compound, or may be some combination or ratio of several plant hormones, produced by one or more genes in the plant. Almost all these factors are outside our control, once the plant is in the ground, so the best we can do is pay attention and be ready to act.
There is a bit more information about the triggers for bulb initiation and for drying down. Garlic bulb initiation (and the end of leaf growth) is triggered by daylight increasing above13 hours in length (April 10 here at 38°N). Soil temperatures over 60°F (15.5°C) and air temperatures above 68°F (20°C) are secondary triggers. When I was in Jamaica last May, I researched growing garlic in the tropics, and it may be that temperature is a bigger trigger and daylength is less important in tropical latitudes where daylength does not vary much. Certainly some growers had produced garlic when I didn’t expect it to be possible.
Hot weather above 91°F (33°C) ends bulb growth and starts the drying down process. I don’t yet know how many hours over that temperature the garlic needs before drying down is triggered. We had a few very hot days last week.
It is important to get plenty of good rapid growth before conditions prevent any more growth. Garlic can double in size in its last month of growth, and removing the scapes (the hard central stem) of hardneck garlic can increase the bulb size 25%.
In the 2015 post I described how we pull our garlic scapes, to get the most out–we love this crop! We also appreciate a late-morning task that’s done standing up! In that post I described the value of mulch and when to remove it.
Here’s the short version. Those looking for more detail can go to my 2015 post.
When scapes arrive, plan some late morning or early afternoon time two or three times a week to harvest them.
As soon as the pointed cap of the scape has emerged above the plant center, firmly grasp the stem just below the cap and pull slowly and steadily straight up. The scape pops as it leaves the plant and you have the whole length of the scape, including the tender lower part.
Gather them into buckets, with the scapes upright, so they are easy to bunch or cut up.
Put a little water in the bucket.
They store well in a refrigerator for months if you don’t use them sooner.
In a few days, more scapes will have grown tall enough to pull, and you can have a second chance on any that broke at your earlier attempt.
In May our outdoor planted scallions start. For outdoors, we use transplants, started in January and February, and transplanted in March and April. We sow in Speedling plug flats, a small pinch of seed in each cell, and transplant the undivided clump/plug. We can get a lot of scallions in a small space. Around May 10, the first ones are big enough to harvest (just as the hoophouse ones finish up – what planning!)
To harvest, we loosen the soil with a digging fork, then lift out a clump. We shake the plants, keeping them in a cluster, and trim off the roots and the ragged tops. Holding the bunch in one hand, we pass the scallions one at a time to the other hand, pulling off a single outer leaf and giving the base of the plant a wipe with our spare hand. Next we set the scallions in a small bucket in water. When the bucket is full enough, we dunk the scallions up and down, and transfer them to a clean bucket with a small amount of water to keep them fresh.
It’s good to develop an efficient method with little scallions or the harvest takes way too long. Deal with scallions in bunches as much as possible (digging up, trimming), rather than one at a time. Pass them from hand to hand when cleaning rather than set them down on the ground and pick them up again one at a time. Set them into water so they are cleaning themselves while you work on the rest. Don’t fuss with them too much – pull off a single outer leaf, not more. Don’t pick at little bits of skin, unless quite gross. If you are going to band them, start out with a bunch of rubber bands around three fingers on the hand that holds the bunches (leaving the forefinger free for tasks demanding dexterity). When you’re ready to band them, use the other hand to pull a rubber band into position.
Roxbury Farm in New York State has a wonderful Harvest Manual. Page 45 on scallions says they harvest 50 bunches an hour, including trimming tops as needed, but not roots. They wash 100 bunches an hour on a bench, in bunches, with a power spray.
Harvesting fall-planted potato onions
Potato onions (Allium cepa var. aggregatum) are a type of hardy, perennial multiplier onion–once you have them you are self-sufficient. You don’t need to buy seed each year, but select the best bulbs from the ones you grew to replant for the next crop. Also known as Hill Onions, Mother Onions and Pregnant Onions, they produce a cluster of tasty (but not too pungent) bulbs from a single planted bulb, or a large bulb from a small one.
Potato onions have good drought resistance, pink root resistance, onion fly resistance and are widely adapted for different growing regions (not Florida or southern Texas). When properly planted they can withstand sub-freezing temperatures in every area of the continental U.S.
The potato onions which were planted earliest (September for us) will be ready to harvest first, at the end of May or early in June in our central Virginia climate. Once you see the tops start to fall over, stop watering the onions and let them dry down.
Potato onions are ready to harvest when the tops die. Not all will be ready the same day. Because onions easily get sunscald if left exposed after they are mature, it’s best to harvest the mature ones every few days. Don’t break over the tops in hopes of a single harvest–it really reduces the storage life. The potato onions sit on the surface and are easily picked up without tools. Handle them gently, to prevent bruising and scratching. Put them into crates or buckets, without pulling off any leaves.
The September planted potato onions were the largest bulbs when planted, and they will usually have divided and produced clusters of small onions. Do not break up the clusters as you harvest, because this triggers sprouting. Set the clusters in a barn or shed, on an airy bench or horizontal rack. The tops break easily, so you cannot hang them as you might hang garlic. Potato onions need good ventilation: we use box fans continuously.
If you find any bulbs larger than 2.5″ (about 6 cm), go ahead and eat those. The giants do not store well. Alternatively, refrigerate them till September and replant. The small and medium-sized bulbs keep 8-12 months under good conditions, and are the best to replant to grow more onions.
Potato onions need sorting about once a month to remove any that are rotting. We plant our large ones in September or early October, our medium-sized ones in late November and our small ones in late January. I’ll tell you more about those when the time comes.
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.
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.
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
July 2018 update: This is one of my most popular posts. I’ve written much else about garlic too. Just put “garlic” in the search box and you can read much more.
Our garlic scapes are just starting to appear! Garlic scapes are the firm, round flower stems that grow from hard-neck garlic, starting (on lour farm) to appear 3 weeks before bulb harvest, as the bulbs size up. If these are removed, the garlic bulbs will be bigger and also easier to braid, if you want braids from hardneck garlic. Contrary to ideas mentioned by some sources, leaving scapes in does not increase the storage life. Most people who remove scapes cut them where they emerge from the leaves. We prefer to pull ours, to get the most out. Scapes also make a visually attractive early-season crop.
Day-length as well as accumulated growing degree days determines when scapes appear as well as when bulbs are ready to harvest. Hot weather above 91°F (33°C) ends bulb growth and drying down starts. It’s irreversible. It is important to get plenty of good rapid growth before hot weather arrives. Garlic can double in size in its last month of growth, and removing the scapes (the hard central stem) of hardneck garlic can increase the bulb size 25%.
This is a good time to be paying more attention to your garlic crop, and what better way than walking through pulling scapes?
We harvest ours two or three times a week, for three weeks in May.
Late morning is a good time to pull scapes (or early afternoon). The wound heals quickly then, reducing the risk of disease, and the water-loss from the plant.
We don’t wait for the top of the scape to loop around (as seen in the photo to the left), as the scapes begin to toughen and reduce the final yield of the garlic.
As soon as the pointed caps of the scape have cleared the plant center, grasp the round stem just below the cap and pull slowly and steadily vertically upwards. The scape emerges with a strange popping sound and you have the full length of the scape, including the tender lower portion. See the photo from A Way to Garden at the end of this post.
It’s an enjoyable task – a stand-up job, and there’s a friendly competition to see who can get the longest scape. (Encourages everyone to perfect their technique.)
Sometimes the scapes will snap rather than pull right out, but the remainder of the stem can be pulled next time, when it has grown taller.
We gather them into buckets, with the scapes upright, and put a little water in the bucket.
The scapes are aligned, easy to bunch or cut up.
They store well in a refrigerator for months if needed.
Scapes can be chopped and used in stir-fries, pesto, garlic butter, pickles and other
dishes in place of bulb garlic. They can also be frozen for out of season use. Searching the Internet will reveal lots of recipes.
Scapes sell in bunches of six to ten.
1 acre (0.4 ha) of hardneck garlic produces 300-500 lbs (136-226 kg) of scapes.
Take the opportunity to remove any diseased plants from the patch at the same time.
While harvesting scapes, monitor the plants for signs of maturity. Garlic is ready to harvest when the sixth leaf down is starting to brown on 50 percent of the crop. See Ron Engeland’s excellent book Growing Great Garlic for more on this. For some years I was confused about which was the “sixth leaf,” and I confess that I was counting up instead of down. The point is to have five green leaves still on the plant, to provide the protection of five intact skins over the bulb. Each leaf corresponds to one wrapper on the cloves or bulb; as the leaf dies, the skin rots away. Keeping five intact skins on the garlic is a challenge in our humid climate, and because we are not shipping our garlic anywhere, it seems less crucial. So I also use a second method of deciding when to harvest: I pull three or four plants and cut the bulbs across horizontally and look at the center of the bulb. When air space becomes visible between the round stem and the cloves, it’s time for the garlic harvest. Usually that’s June 7–June 14 for our main crop of hardneck garlic, but it has been as early as May 30, and as late as June 18. Harvesting too early means smaller bulbs (harvesting way too early means an undifferentiated bulb and lots of wrappers that then shrivel up). Harvesting too late means that the bulbs may “shatter” or have an exploded look, and not store as well.
This is also a good time to remove the mulch to help the bulbs dry down, and to prevent fungal diseases.
In our rotation, the spring broccoli is usually next door to the garlic, and we move the old garlic mulch to the broccoli to top up the mulch there. It helps us stay on track with getting the broccoli weeded too.
The value of mulching garlic and how-to
Organic mulches will protect the cloves from cold winter temperatures, and frost-heaving to some extent.
In the South organic mulches keep the soil cooler once the weather starts to heat up. It is hard to add mulch after the garlic has started to grow.
We roll big round bales of spoiled hay over our beds immediately after planting in November.
Once we have ensured the shoots are all growing free of the mulch, we leave the garlic plot alone until late February,
In February, we start weeding (and repeat once a month for four months).
Weed control in garlic is important -Weeds can decrease yield by as much as 50%. First kill the spring cool-weather weeds, then kill the summer weeds.
Understanding garlic stages of growth
It is important to establish garlic in good time so that roots and vegetative growth are as big as possible before the plant turns its attention to making bulbs. The start of garlic bulb formation (and the end of leaf growth) is triggered by day length exceeding
13 hours (April 10 here at 38°N). Air temperatures above 68°F (20°C) and soil temperatures over 60°F (15.5°C) are secondary triggers.
We all have 12 hours of daylight on the spring equinox. After that, the farther north you go, the longer the day length is. Northern latitudes reach 13 hours of daylight before southern ones, but garlic does not start bulbing there at 13 hours because temperatures are not yet high enough. For example, in Michigan, bulbing begins in mid-May. In warmer areas, temperatures cause harvest dates to be earlier than in cooler areas at the same latitude. We have no control over when garlic starts to make bulbs, only over how large and healthy the leaves are when bulbing starts, and how large the final bulbs can be. Small plants here on April 11 will only make small bulbs! Watering should stop two weeks before harvest to help the plants dry down.
We had 4.6″ rain over a few days and nights. We had to dig trenches across the potato patch to drain out the water, which had reached the tops of the hills (thank goodness we got the first hilling done before the rain!) We also dug “:flood abatement” ditches at the low end of our raised bed area. Even so, we have been really restricted in where we could work. I tell people to harvest or weed at the dry ends of the beds, and back out as soon as their feet start to sink in mud. I don’t want us to compact the soil and make future drainage worse, and give the roots have a hard time growing. To use the rainy weather, we washed our work gloves and started tackling our “Stuck Buckets” stacks. I don’t think we unstuck any at all last year. We had about 50 or so stuck in pairs or triplets. After wrangling them and trying various back-muscle-risking maneuvers, we run them through our commercial dishwasher. When the plastic is hot, the wet buckets come apart more easily.
We’ve had to be creative in finding work we can do. Tempting as it is to take a big nap, I know we will be scrambling later, as soon as it warms up and dries out. So yesterday we put our blueberry netting up. The berries are still green, in some cases they are still blossoms, but it’s one job we won’t have to do later. We’ve also pre-emptively been organizing our drip tape and setting up systems we won’t need for at least a week.
We’re also starting our leek transplanting. Normally we do this in early June, but this year we sowed our seeds in flats rather than in an outdoor nursery bed, and the plants are big earlier, especially the faster growing King Richard and Lincoln. So we’re going to transplant those today. They are nice and cold-tolerant (we’ve got a forecast low of 34F in a few days!), and will keep us from putting tomato plants out too early and regretting it later.
Starting to harvest garlic scapes lifts our spirits because it is a tasty attractive new crop for the year, and pleasant work. Here’s what I wrote about them for my book, Sustainable Market Farming (c) Pam Dawling 2013.
Garlic scapes are the firm, round seed stems that grow from hardneck garlic and start to appear three weeks before harvest, as the bulbs size up. If these are removed, the garlic bulbs will be easier to braid, if you want braids from hardneck varieties. Scapes also make an early-season visually attractive crop. Contrary to ideas mentioned by some sources, leaving scapes in does not increase the storage life of the garlic.
Most people who remove scapes cut them where they emerge from the leaves. We prefer to pull ours, to get the most out of them. We don’t wait for the top of the scape to loop around, as the scapes will have begun to toughen and reduce the final yield of the garlic. As soon as the pointed caps of the scape have cleared the plant center, grasp the round stem just below the cap and pull slowly and steadily vertically upwards. The scape emerges with a strange popping sound and you have the full length of the scape, including the tender lower portion. Sometimes the scapes will snap rather than pull right out, but the remainder of the stem can be pulled next time, when it has grown taller.
We gather into buckets, with the scapes standing upright, so we can put a little water in the bucket and the scapes are aligned, easy to cut up. They will store well in a refrigerator for months if needed. Late morning is a good time to pull scapes (or early afternoon). The wound heals over in fifteen to twenty minutes in the heat of the day, whereas otherwise it could drip for up to 24 hours, increasing the risk of disease, and losing water from the plant.
We harvest scapes two or three times a week, for about three weeks in May. The crew always enjoys this task, partly because it’s a stand-up job and partly because we encourage a friendly competition to see who can get the longest scape of the day. This encourages everyone to perfect their technique too. Scapes can be chopped and used in stir-fries, pesto, garlic butter, pickles and other dishes in place of bulb garlic. They can also be frozen for out of season use. Searching the Internet will reveal lots of recipes. Scapes sell in bunches of six to ten. One acre (0.4 hectare) of hardneck garlic can produce 300–500 lbs (140–225 kg) of scapes.

Till each corn twice, undersowing at 2nd tilling (30 days), when 12” high, with soy for #1-5, oats/soy for #6. Thincorn to 8”. Avoid cultivating corn after it’s knee-high—roots are shallow.
Sowcorn #2, cowpeas #2; cukes #2 (picklers and slicers), summer squash & zukes #2 5/24 (or in greenhouse 5/14, transplant 6/7), watermelons #3, winter squash 5/26 (put woodash with seeds to deter squash vine borer). If squash sowing is late, don’t sow Tahitian butternut – slow. Cover cucurbits (perhaps not winter squash) against cucumber beetles. Max. cuke beetle population is mid-May; keep susceptible plants well-covered until flowering.
Transplantlettuce #9, 10, 11;Roma paste tomato replacements for casualties, insectary flowers. Fill gaps in eggplant, peppers, melons, watermelons.

Harvest fall planted Potato Onions in dry weather, after tops have fallen, (5/25-6/10, spring planted 6/3-18). May not all be ready at once. Handle gently. Dry as clusters in barn on wooden racks for 1-2 months, using fans. Service fans or buy new as needed. Eat potato onions >2.5” without curing, unless yield is very low, in which case label & refrigerate, then plant in September. Weight after drying for 1 week is approximately twice the final weight. First sorting is late June. Use the Worksheet and Log Book
Harvestgarlic when 6th leaf down is starting to brown on 50% of the crop (ie .5 green leaves, so that 5 skins cover cloves), or cut open horizontally- when air space is visible between. stem and cloves it’s time to harvest. [Could replant small cloves immediately for garlic scallions.] Allow 15 mins/bucket harvesting and 15 mins/bucket for hanging in netting in barn,.
Till garlic area, sow soy & buckwheat to control weeds until fall carrot planting.
Plan fall and winter crops for raised beds.
Cover crops: can sow buckwheat, soy, millet, and sorghum-sudan during May.
Perennials: Put up blueberry netting before fruit sets. Weed & water & top up mulch. Mow grape & fall raspberry aisles. New grapevines: remove side branches and fruitlets.

My workshop will cover garlic planting, harvest, curing, storing and the selection of planting stock. As well as hardneck and softneck bulb garlic, we will cover “byproduct crops” such as garlic scallions and scapes, which are ready early in the year when new crops are at a premium. You’ll get the chance for an advance discussion of one of the chapters in my book, and to ask questions and share your experience with this tasty crop.
My book, Sustainable Market Farming, and its chapter on garlic, won’t be published in time for the conference, but I will have postcards and pre-publication fliers which offer a discount for pre-orders.

One of my very first blog posts, on June 14, was about our garlic harvest. Now we have all the bulbs trimmed and stored, and are eating our way into the bounty, and we have several bags of selected bulbs for replanting in early November.
