We’re making good progress with catching up on our big transplanting tasks. We’ve planted the Roma paste tomatoes, peppers, melons, okra, eggplant, yet more lettuce and over half of the sweet potatoes. After this there’s “just” the watermelons and leeks to go. Then only the roughly weekly lettuce planting until the fall brassica transplanting shifts in late July and August. In order to give our transplants the best chance of thriving, we never plant in the mornings (except leeks), and prefer to make the extra effort to plant late in the day. That way, the plants have the cool of the night to get established before being called on to photosynthesize, transpire, extract water and nutrients from the soil, deter bugs and all the many plant tasks we don’t even know about. Currently we are transplanting 4-6 pm each day, with just a small group of people so that everyone focuses on planting and we are not training new people (a feature of our big morning work shifts).

Sweet potato vines grow to completely cover the area and the plastic is out of sight and being digested by the soil micro-organisms. Very little hand-weeding is needed. I think last year we did one walk-through (wade-through!) weeding.
The deer have reappeared and as sweet potato leaves are one of deer’s favorite foods, we got ourselves prepared, installing two Scare Crows, one at each end of the patch. These are water sprinklers activated by motion detectors. We’ve found Scare Crows quite effective against deer. They seem to have dropped off the market. Havahart is selling the Spray Away which looks similar but I haven’t tried. They can only be used during the frost free period, because you have to leave the water supply hooked up. As sweet potatoes will only be in the garden during the frost free period, this is a good match!
This is a fast growing, productive Asian lettuce. It has a sweet flavor and plenty of crunch. In our climate, I think it would not do well in summer. Better for spring and fall. We bought seed from Southern Exposure Seed Exchange You can read about it here, on this TaiwanFinn Blog. “Taiwan (and Luxembourg) Through the Eyes of a Finn”. one comment says this is known in the English-speaking world as Celtuce. But Kitazawa Seeds sells both. With celtuce, the stem is the main part eaten. With Sword Leaf it is the leaves. So I’m doubting they are the same.

Like many people in our area of the mid-Atlantic, we’ve had a lot of rain. 8″ in June, including a ten day dry spell, so 8″ over 20 days. Some of our 540 Roma paste tomatoes suddenly wilted, about ten days ago. Argh! Were our tomatoes drowning or was it the dreaded Bacterial Wilt?
My first response was to stop everyone touching them. No string-weaving till we figured out if the problem was contagious or not. Then I read up about Bacterial Wilt(Ralstonia solanacearum, formerly called Pseudomonas solanacearum). ” Plants wilt and die rapidly without the presence of yellowing or spotting of the foliage”. We had the rapid wilting, with no yellowing or spotting. “The disease is most commonly found in low, wet areas of fields and is most active at temperatures above 75 degrees F.” Check, check. But drowning is most common in low, wet areas too! The affected plants were in the lowest areas, but that didn’t tell us whether it was drowning or bacteria causing the problem.
Next I counted the wilted plants in each row. The total was 81 plants the first day, 92 the second (uh-oh!), but 65 the third day, 51 the fourth day, up to 57 the next day, then 41. By this time I was concluding these plants were not dying rapidly, so maybe it wasn’t wilt. One site said plants could die within a few hours of starting to wilt. Other sites said plants could wilt a bit in the middle of the day, then recover at night. I don’t think that’s Bacterial Wilt.
The third day I sacrificed the worst plant and cut through the stem to look at the xylem (water conducting pipes). Yes they were brown, not happy. Does that happen in drowning plants or just those infected with bacteria? I don’t know. The cut ends weren’t sticky, as suggested for bacterial wilt, didn’t pull out sticky threads when pressed together and pulled apart. So next I tried the definitive test for tomato bacterial wilt: I cut a length of stem, stabbed it through with a knife and suspended it in a jar of water to watch for milky bacterial ooze streaming from the cut. Initially a small amount of something gently fell from the cut end. Then stopped. I watched for 5 minutes (some sites said it took several minutes for the ooze to leave). Nothing more happened. I’ve decided they were drowning, so we’re back to string-weaving.

We transplanted these around May 5, and tomorrow we’ll do our first harvest (about 66 days from transplanting). These are listed in Southern Exposure Seed Exchange catalog as 75 days from transplanting to harvest. We grow these Virginia Select Romas here in our garden and sell the seed to SESE. I’ve been selecting for earliness (as well as good yields and tolerance to Septoria leaf spot) and I’ve been wondering what impact I’m having on the “earliness” part of the equation. Seems like it’s working well.
Meanwhile, the plants are recovering from near-drowning and assaults by all manner of other disease organisms that like warm damp weather. I see some Septoria, some early blight, but abundant healthy foliage too.I think they will outgrow the current issues.
Trimming garlic. Photo Brittany Lewis
We have been making great progress trimming and sorting our garlic. We’ve trimmed it all! In just a couple of weeks! Yay for us!
But as soon as the tomato trouble gets resolved, another problem arises. Some of our softneck garlic bulbs have onion maggots! What to do? We also had a problem with helpers bagging up garlic before it was fully cured, so we’ve spread the trimmed bulbs back out on racks to finish drying. Is there anything we can do about the maggots? If you have suggestions, please add a comment! I know what to do to reduce our chances of getting them in future: pay attention to rotations, practice good sanitation by removing all allium bits from the plot when we harvest, control weeds ahead of planting garlic (and of course while it’s growing!).
My understanding of the life-cycle of the onion maggot is that pupae overwinter in the soil, adults emerge in spring. 9 days later they lay eggs at the base of plants. Eggs hatch in a week, maggots burrow into the roots of the plants, spending 2 or 3 weeks up to no good. Then they leave the bulbs and head back into the soil to pupate. If we leave our garlic on racks for three weeks, will the larvae just drop to the ground below the racks? Can we then sort the good bulbs from the bad? Will they all be infested by then? It seems biologically determined that the larvae leave after about 3 weeks. How much damage will they do while we wait?
Or can we try sorting good bulbs from bad now? We’ll need to take a closer look at the crop and see what we can do. We also wanted to save stock for replanting, and obviously don’t want to replant infested cloves. Any there any garlic experts reading this?

Sort Potato Onions 6/20-6/30 (without breaking clusters), starting with the biggest, and remove rotting ones. Remove ones >2” for eating, or refrigerate for September planting; or sell to Southern Exposure Seed Exchange before 7/31. Continue to cure small and medium ones for 2 months or more in total, with fans. Use Worksheet and Log Book. Be sure to write down where you store them!
Store any seeds not needed until fall (okra, nightshades, peanuts, melons) in basement
Snip, sort and store garlic after curing 2-4 weeks. Store at 60-70°F (basement), never 40-50°F. Seed garlic is best stored in garden shed (or 32-35°F).

At last we are getting our warm weather crops transplanted! We finished our 530 Roma paste tomatoes and I’ve just seen this afternoon’s crew of two go past the office window with watermelon starts on a cart. We’re late, but we’re getting there! We have about 260 Crimson Sweet watermelons to go in, and cover to keep the bugs off. This morning, working with the large crew, we set out the ropes and the sticks to hold down the rowcover. Our method is to use the big morning crews to harvest and to get ready whatever will be needed for the small late afternoon transplanting shift, so all they have to do is plant, water and cover. This makes best use of the cooling temperatures later in the day.
After the watermelons, we’ll still have peppers, eggplants, muskmelons (cantaloupes), okra and lots of sweet potatoes to go in. And more lettuce every week.
Meanwhile the brood II 17-year cicadas are in good form. So loud. The ground around the trees is riddled with holes from the emerging juniors. The cast-off shells/exoskeletons are crunchy underfoot. Someone here saw squirrels eating cicadas but I haven’t seen it yet myself.
The other thing I want to write about is our blueberry netting and its seasonal hooped structure. I think this is a good method that more people might like to use. Our older blueberry patch has a rectangular framework made of posts with wires joining the tops. the netting is a fairly rigid square plastic type that is a challenge to put up. This new type is a big improvement – easy to put up and get the netting over, and removable so we don’t have to look at the framework all year.
Our new blueberry area is 16′ x 65′ approx. The height of the netting supports needs to be 7′ or more for most of the space. The 20 blueberry bushes are 66″ apart, in two rows.
We looked at these options, then found a few more:
3/4″ PVC water pipe,
20′ rebar inside PVC piping
Fiberglass poles fixed to T-posts
Galvanized steel tubing, as sold for small hoophouses.
Metal electrical conduit bent into a curve, connected at the ridge.
Other tubing, such as chainlink fence top-rail, metal water pipe, curved.
“Spider-House” temporary framework
Wood-framed structure
Bamboo
We chose PVC Electrical conduit. Plastic electrical conduit, unlike water pipe, is UV-inhibited for outdoor use. Lengths have swaged (flanged) ends, so can be joined without any separate connectors. Lightweight, no bending tools needed (unlike for metal conduit or fencing top-rail). Packs flat for out-of-season storage. Relatively cheap.
We use a “Spider-House” temporary framework – an idea used for temporary “field hoophouses”. It consists of pairs of bows fastened together at the apex, in a way that spreads out into a 4-legged structure. A row of these make up the frame. An advantage is that the spiders are stronger than simple bows, and that the whole thing can be dismantled relatively easily. Helps add strength to lightweight bows.
I’ll tell you how we did it, then talk about the options we didn’t choose.
We bought very nice flexible nylon netting from Lee Valley. We chose the 12’ x 117’ ½” mesh, and I stitched two lengths together using nylon thread, making a piece 24’ wide. It should last a long time. It isn’t cheap. It does not ravel when cut, or snag on itself. At the end of the season it can be stuffed in a bag, with just one end poking out of the neck of the bag. Then next year, drop the bag at one end, pull the free end of the netting up over the piping and along the length of the berry patch. Our netting is longer than the patch, but we plan to extend the patch one day. . .
For our 16’ x 65’ patch, we decided on three “spiders.” Our calculation was that 30’ hooped into a half circle would have a diameter of 19’ (divide circumference by pi to get radius, then multiply by two). So we reckoned having the ends of each pipe 19’ apart, crosswise across the patch. A bit of Pythagoras leads to a spacing along the length of the patch of just over 10’ for a width of 16’ and a diagonal of 19’. We don’t need perfect half-circles, but we did need a rough idea of a workable length.
We bought 18 pieces of 3/4” PVC electrical conduit in 10’ lengths with swaged (belled) ends.
We glued them in threes to make 30’ lengths.
We marked the center point of each length, matched centers of two lengths, then tied a pair of lengths together to form a cross shape. If you were in the scouts, square lashing is the type of knot you need.
We got 12 4’ lengths of rebar and hammered them halfway in the ground along the long edges of the plot, 12’ 6” apart (six rebars, 5 spaces of 12’ 6” equals 62’ 6”). Close enough.
We popped the spider legs over the rebar, making sure all the lumpy knots were on the underside of the tubing crossovers, to make it easier to pull the netting.
When we had all three four-legged spiders in position, we pulled over the netting, and pinned it down every 18” round the edges with 1” wide sod staples/landscape pins.
We have a doorway along the central seam, simply held closed with clothes pins.
Here’s our thoughts about the ideas we didn’t take up:
PVC water pipe. A small experimental structure at Twin Oaks, made from 3/4″ pipe collapsed in the winter, (but need not have). Cheap, easy to bend, easy to replace. Can install for seasonal use on rebar pieces in the ground (which could be an off-season hazard….). Using PVC glue is smelly and unhealthy. Not cheaper than PVC electrical conduit. See Constructing a Simple PVC High Tunnel by Jim Hail, Robbins Hail, Katherine Kelly, and Ted Carey for a 30’ x 18’ hoophouse from 1” PVC.
There is a smaller design “Portable Field Hoophouse”, using 3/4″ rigid white schedule 40 pvc in 18′ lengths to give a 10′ wide frame for an 18-42′ length hoophouse with no ridgepole.
PEX water pipe tubing: Too bendy
Metal electrical conduit bent into a curve, connected at the ridge. Conduit is cheap and readily available. It can be bent with purchased pipebenders (if the right shape is available), or on a wooden jig, or round stakes hammered into the ground. Lost Creek sells pipebenders. Johnnys sells Quick Hoops Benders but they make 12’ x 7’ high tunnel or caterpillar tunnel hoops only. They have a video on the site.
Other metal tubing, such as chainlink fence top-rail, or metal water-pipe, bent into a curve. Either use the commercially available pipebenders, as above, or make your own jig. There are good plans by Jamie and Tod Hanley using square tubing, and a home-made bending jig. Square is easier to bend without twisting, but that might not be important for this project.
More plastic tubing (1” x 20’) hoophouse frames and a metal tubing frame as well as photos and details of a bending jig for metal water piping, on the New Farm website, using 3/4″ galvanised piping in 21′ lengths. Their jig consists of 20 short pieces of 2×4 lumber screwed down on the bed of a hay wagon.
Pre-curved galvanized steel tubing, as sold for small hoophouses. Farmtek has a wide range of ready-made hoop parts, including tall, round-topped styles. Shipping adds to the cost. More expensive than other options.
20′ rebar inside PVC piping. Idea from Cindy Connor for small hoophouses. Stronger than PVC pipe alone. 5/8″ rebar could be used alone (but hard to pull fabrics over).
Fiberglass poles fixed to T-posts. T-posts would stay all year, fiberglass poles stored out of season. Straightforward to do. Splinters from fiberglass could be a problem long-term.
Wood-framed structure. A lot of work, but cheap. Clunky. Might take too long to make.
Bamboo. Free if you have invasive bamboo, but a bit of work. The nodes would snag on the netting. Saw then sand them off? Duct tape?

What a week! With the forecast for low temperatures on Sunday and Monday nights this past week, we back-pedaled on our transplanting plans. The tomato plants in our coldframe were very tall. In order to cover them we extended the cold-frame height by balancing plastic crates on top of the blockwork walls. Setting the lids on top of this construction was a bit precarious, but it worked well. Only a few of the taller tomatoes got nipped at the very top on Monday night when the temperature plummeted to 30F. 5/14 is very late for a last frost for us. Our average for the past ten years is 4/30, but in 2009 it was 5/19. In 2011 it was 4/14. Farming is full of surprises!

On Tuesday we started transplanting tomatoes. Hot dry windy weather. On Wednesday 5/15 it reached 90F. On Thursday afternoon we planned to continue the big transplanting of our Roma paste tomatoes. Three rows are in mowed no-till rye, vetch and winter peas cover crop and one row is on black biodegradable plastic mulch. (Here’s an interesting link to a comparison of the two biggest brands of biodegradable plastic mulch. http://extension.udel.edu/ag/files/2012/03/2012DegradableMulchWM.pdf) But Thursday’s shift was inauspicious. We started with only 5 of us (we plan for 7). One person had to leave at 4pm. One person was called away to bale hay. Another person agreed to provide childcare for the person baling hay, from 4-6pm. Then another person started to feel ill, and left the scene. The 3 of us still working at 3pm started to sow our second zucchini and summer squash. We each used two dowels to make holes every 6″ in the biodegradable plastic mulch. We got the holes popped through, but then another community member cycled by and warned us of a strong thunderstorm heading right for us. Discretion being the better part of valor, we retired for a tea-break and to consult the local radar on Wunderground. An intense “red and yellow” storm, not very wide (ie not very long-lasting), was due any minute. Once it started to rain we decided to quit trying to garden for the day. good thing too. We got an inch of rain in an hour. Too bad the soil hadn’t dried out enough for us to do a second hilling of the potatoes before this new rain. or make ridges for sweet potatoes. Now we’ll have to wait another week, during which there is 20-80% chance of some rain every day except Monday, when it is forecast to be foggy. So I’m getting closer to finishing reading my library book. . .
April 2013 Growing for Market
Meanwhile, in the Mental Gardening Department, I found I had made mistakes in my Growing for Market articles on parsnips and fennel, about which plants can cross-pollinate each other. So I wrote an apology and correction. One of these mistakes is in my book. In case you are reading my former, deluded, beliefs, here is the correction: On parsnips, the facts are that parsnips can cross with wild parsnip, but not with carrots or Queen Anne’s Lace, as I wrongly claimed.
On fennel, the facts are that fennel does not cross with anything except other fennel. It is widely said (even by some seed companies!) that dill and fennel cross, and some even describe the terrible flavor of the resulting crosses. Clearly this is a superstitious belief that continues because acting on the belief produces good fennel (or dill) seed. Similar to how someone might snap their fingers to keep away tigers – no tigers – complete success! I’ve long believed dill and fennel crossed. It’s good to know I don’t need to worry about that any more.
This is the first error I’ve found in my book. Soon New Society wants a list of corrections from me, for when they do a reprint. I’ve only found this and one formatting glitch so far. Embarrassing, but I repeat my Mantra for Consolation: “The only people who never make mistakes are those who don’t do anything.” On Monday I did an interview for Lightly on the Ground Radio on wrir.org (Richmond Independent Radio) with Sunny Gardener. I’m learning how to find and download the podcast (so many technical skills to learn!) I’m working on a powerpoint presentation on Planning Fall Vegetable Production, for Virginia State University’s Summer Vegetable and Berry Field Day on June 27 at Randolph Farm. This will lead nicely to my Last Chance Sowings article for the August Growing for Market and a Cold-Hardy Winter Vegetables presentation for the Mother Earth News Fair in September
Here’s my list of upcoming presentations and workshops:
June 27 VSU Randolph Farm. Planning Fall Vegetable Production
Here’s our list of tasks for October. If you garden in zone 6 or 7, your list might be similar. If you live in a very different climate zone, leave a comment about your list for October, and how many weeks different your area is from ours.
During the month
Weed and thin fall crops in raised beds, especially spinach and kale. Thin carrots to 3”, kale to 12”.
Lettuce Factory: Transplant sowing #37 to fill cold frames; #38, 39, 40, 41, 42 in Greenhouse beds (9″ spacing).
Frost Alert:
Watch the forecast and if frost is expected that night
When frost threatens, harvest all peppers exposed to the sky. Corona is one of our favorite orange peppers. Photo credit Kathryn Simmons
Harvest peppers facing the sky, tomatoes, cauliflowers, corn, cowpeas, limas, eggplant, melons, cukes, okra, winter squash, Blues cabbage (hardy to 25°F), if not already done.
Double hoop and cover: lettuce, celery (hardy to 16°F with row cover).
Spring hoop and cover: squash, cucumbers.
Cover celery to extend the harvest into mid-winter. We like Ventura. Photo credit Kathryn Simmons
Rowcover (no hoops): beans, Chinese cabbage, pak choy, Tokyo bekana, seedlings for hoophouse, collards (hardy to 10°F, but cover keeps quality).
Cold frames: Row cover between 32-28°F. Add lids between 28-15°F. Add quilts below 15°F.
Foliar spray greens with seaweed a few days before frost, to toughen them up.
Use overhead irrigation on peppers & tomatoes at night and some raised beds with tender crops.
Early Oct: Finish sowing spinach, kale by 7th for overwintering (last chance).
Transplantlettuce #37 to fill cold frames; #38, 39 in Greenhouse (9″ spacing).
Roll updrip tape from winter squash and sweet potatoes.
It’s time to roll up the drip tape from the watermelon, winter squash and sweet potato patches, in preparation for disking and sowing winter cover crops. Photo credit Kathryn Simmons
Movestored garlic from basement to fridge – store below 40°F or above 56°F, never 40-50°F.
Mid Oct: Till finished raised beds and sow wheat or rye before the end of the month.
Garlic Beds: Compost (5-6 tractor buckets), till and prepare beds.
Transplant lettuce #40, 41, 42, 43 in Greenhouse as needed, filling any gaps.
Get soil tests done, when soil is not too wet.
5thfall disking: By mid-month disk and sow cover crops where possible. Sow wheat or rye as covercrops – too late for oats or most clovers (Austrian Winter Peas Sept 15-Oct 24). Could sow winter wheat mid-Sept to early Nov (good for small plots that are hard to reach with the tractor) and after sweet potatoes).
Harvestpeanuts mid-late Oct after a light frost. Wash, dry, cure 6 days in solar dryer facing east (don’t heat over 85°F), store.
A well-covered sweet potato patch. Photo credit Kathryn Simmons
Harvest sweet potatoes before soil temps go much below 55°F, or night air goes below 50°F: on 3 mild days – generally in the week that first frost usually occurs (10/7-14). Even a few hours exposed to temps below 50°F will cause chilling injury. (Frost on the leaves does not of itself damage the roots). Clip vines, dig carefully, set tubers in plant-clusters to dry on the soil. Select seed tubers (med-size tubers from high-yielding plants). Save 100 Georgia Jet, 100 Beauregard, 20 each White and Jubilee. Cure in boxes with wood spacers and cover with newspaper, in basement with furnace going full time, for 7-10 days (85-90°F, 80-90% humidity). Use fans. Splash water on floor. Curing is complete when skin is undamaged after rubbing two together. Restack boxes in storage cage.
Harvest white potatoes before the first frost (average Oct 14) if possible. Cure in root cellar at 60-75°F for 2 weeks, with good ventilation, then cool the cellar to lower temperatures: 50°F by 10/31, then 40°F for the winter.
Late Oct:Transplant lettuce #44, 45, 46 as filler in Greenhouse. Double hoop and cover spinach.
Planning: List successes & failures from labels. Prepare Garden Planning Schedule, Crop Review Sheets. Clean labels after info is recorded. Pray for a killing frost. File crop record info. Audit labor budget and plan endgame. Plan main garden layout. Hold Crop Review meeting.
Clearwinter squash, tomatoes and peppers in order to sow cover crops, by 10/24 if possible. Sow rye alone or with crimson clover or winter peas. Crimson clover by 10/14; AWP, wheat by 11/8
6th fall disking: After the killing frost, or end of Oct if no frost: pull up tomato stakes and roll up drip tape, disk nightshades, melons, winter squash, sweet potato and white potato patches.
Check through veg in storage, squash once a week, white potatoes two weeks after harvest.
Perennials:Last mowing of clover in grapes in early Oct, not too short, and not too late in the year. Weed & mulch strawberry beds, and remove extra runners. Renovate if not already done. Start weeding, fertilizing and mulching the blueberries, raspberries, rhubarb and grapes.
Time to say goodbye to the rhubarb until April. Photo credit Kathryn Simmons
October Harvests: Asparagus beans, beans, beets and beet greens, broccoli, cabbage, cantaloupes, carrots, cauliflower, celeriac, celery, chard, Chinese cabbage, collards, corn, cow peas, cukes, edamame, eggplant, horseradish, hot peppers, kohlrabi, komatsuna, leeks, lettuce, limas, maruba santoh, okra, pak choy, peppers, radishes, Roma paste tomatoes, scallions, senposai, spinach, tatsoi, tokyo bekana, tomatoes, turnips and turnip greens, winter radishes, winter squash, yukina savoy, zucchini. Could lightly harvest rhubarb before frost.
