Cooking Greens in June
Summer has arrived here in central Virginia, and most of the spring-planted cooking greens have bolted and been cleared to make way for warm weather crops. And it’s already time to start work on the fall greens, sowing most of them this month. We have no cooking greens to transplant this month (it’s going to be too hot!).
See the chapter Other Greens: Chard and Other Summer Cooking Greens in Sustainable Market Farming for more about chard relatives and amaranths.
Cooking Greens to Harvest in Central Virginia in June
Chard is our queen of summer cooking greens! Because it is a biennial it will not bolt in the summer heat. We can eat it whenever we get the urge, until winter. Apart from the flavor, this is why I value chard: it is always there, always harvestable, from late May to late December. It’s so easy to care for, and nothing bad happens if we ignore it. Some years it even survives our winters. This year we have planted two beds instead of our usual one. We have Bright Lights multicolored chard and Fordhook Giant green chard. We also planted some Lucullus this year, to try. Some years we grow Perpetual Spinach/Leaf Beet, a chard with thin green stems and more moderate-sized leaves. This crop is the closest hot-weather alternative to actual spinach that I have found.
In addition to chard, we are harvesting beet greens as we pull our biggest spring-sown beets. By the end of June we will have harvested all the beets, putting the excess into cool storage over the summer. And so the beet greens harvest will end then too. Some years, the quality of the beet greens does not hold up as late as the end of June. We’ll see.
We continue to have broccoli until the end of June or early July, when we expect it to get bitter, and to only have tiny side-shoots left. We have started harvesting our early cabbage. This year we grew Early Jersey Wakefield, a pointed 2-3 pound (1-1.5 kg) OP cabbage that matures in 63 days. We sowed this in our greenhouse in late January and transplanted it around March 10.
Later we will harvest Farao (F1, 60d, 3lbs, 1.5 kg), more Early Jersey Wakefield, and flat, mid-sized, Tendersweet (F1 71d) from our April 1 transplanting. We store cabbage beyond our immediate needs in net bags in the refrigerator. None of these spring varieties are long-storers, but they should see us through the summer until mid-October when we have fresh outdoor fall cooking greens.
We do still have two beds of collards, Georgia Green and Lottie’s, which we bare-root transplanted from our hoophouse in mid-March. We also have two beds of kale, but these are past their prime and due to be clear-cut any day. June 5 is our usual end-date for kale.
Cooking Greens to Sow in Central Virginia in June
Sow the fall brassicas – see the Special Topic below for all the details.
Early Purple Sprouting Broccoli, is one of the broccoli staples in the UK, and is hardy down to 10°F (–12°C). I’m not sure it would survive in our winter-hardiness zone 7 climate, but one of these years I want to try it, as it’s a wonderful crop.
Early Purple Sprouting broccoli has an extremely long growing season, needing 220-250 days to reach maturity. It is grown overwinter for late winter/early spring harvest. Late spring/early summer is about the right time to be sowing it. If you decide to try it, know what to expect. These are big tall plants, and they produce florets, not big heads.
Other Cooking Greens Tasks
Maybe bushhog the spring broccoli (after harvest is finished) to reduce the habitat for harlequin bugs, our worst brassica pest. The cabbage will continue to grow and mature until mid-July, so we cannot disk up the plot until it is all harvested. We often sow a short-term cover crop such as buckwheat after clearing our spring brassicas.
Special Cooking Greens Topic for June: fall brassica sowing, field planning and preparation
In May, I described our planning for our fall brassica nursery seedbeds. In the third week of June we start the weekly sowings, hooping, netting, watering and weeding. We sow around a foot (15 cm) of seed row for every 12′-15′ (4-5 m) of crop row, aiming for 3-4 seeds per inch (2.5 cm). When I’ve been responsible for this job, I set aside an afternoon a week on a regular day. It takes a surprisingly long time to get all the details right. It is important to be timely, because a one-day delay in sowings for fall can lead to a one week (or longer) delay in harvest date. The shortening daylight slows down the growth.
In Week 1, we sow the fall cabbages – this year Tendersweet F1 71d; Tribute F1 83-103d, 10-12lbs (4.5-5.5 kg); Ruby Perfection F1 85d, 4-7lbs (2-3 kg); and Storage #4 F1 80-90d, 4-8lbs (2-3.5 kg). In Week 2, we repeat the cabbage sowings and sow the first broccoli. Weeks 3-6 fall in July, so I’ll tell you more next month. Weeks 7 and 8 are in August. See the schedule in May’s Cooking Greens post.
In summer weather, brassicas are the right size for transplanting (5 true leaves) in just three weeks, so we need to have the field ready for July 14. We disk in the winter cover crops, and if we didn’t have enough legumes in the mix, we spread compost. Or we spread some anyway, for the micro-organisms more than the plant nutrients. Then a week later, when the cover crops have started to break down, we disk again. Then we measure and flag the rows, and out up stakes and ropes to mark the rows. This helps us get the plants in a straight line (better for quick efficient cultivation), plus the ropes can support the netting we need to use for the first 4 weeks to keep the bugs off.
Next we make a fall brassica transplanting map, or field map, to show where we intend the various varieties to grow. We plan to have the broccoli varieties planted out in order of days to maturity, to make harvesting easy. We make the maps to scale so that if we switch variety in the middle of the row, we can show where the transition happens. Here I have chopped off some row length (extra bare space) at the right, so you can read the text.
Our map for 2016 shows rows of 265′, except for cabbage in rows 3 and 4. This is because the garden edge curved round and there was less space for those rows.
