HOT DAYS, BUT PREPARING FOR FALL

Ignoring My Gut

Like other parents, I don’t hold back preparing for fall just because of hot, sun-drenched sunny days. But my preparations don’t entail trips to the store for notebooks, pencils, rulers, and other school gear. My daughter is old enough to gear up for herself. Instead, I’m preparing for a garden that becomes lush with ”cool weather” vegetables just as tomatoes, peppers, okra, and other warm weather vegetables are fading OUT.
    Much of gardening entails NOT going with your gut. If I went with my gut, I’d be planting more tomatoes and sweet corn and, perhaps, if I was really going with my gut, even banana trees on today’s ninety plus degree, bright, sunny, humid day.

Sprouting seedlings, planting seeds, and transplants

Sprouting seedlings, planting seeds, and transplants

    Although tomatoes, peppers, and cucumbers presently have more appeal, fall vegetables will have their day. I have to remind myself how a lowering sun and cooler weather make more appealing the lush green leaves of cabbages, brussels sprouts, endive, lettuce, kale, celery, and, below ground, radishes, turnips, carrots, and celeriac. And anyway, I’ll have no choice because summer vegetables will have waned by then.
    That lush fall garden, almost like a whole new garden, comes about only if I do something about it now!

To Every Thing There is a Season, a Time to Plant, A Time to…

    Timing is (almost) everything for a productive fall garden. Planted too early, some leafy fall vegetables bolt — send up tough seed stalks — because of heat and long days. Right now, I’m sowing turnips and winter radishes, the especially tasty varieties Hakurei and Watermelon respectively. Among leafy, salad vegetables, lettuce, mustard (the variety Mizuna), and endive, with repeated sowing of lettuce every weeks until early September.
    It’s still a too early for spinach, arugula, mâche, short season Chinese cabbages, and spring radishes. Some time later this month would be about right for these vegetables. My book, Weedless Gardening, gives a detailed schedule for when to plant what vegetables for specific regions.
    For a truly bountiful fall garden, more advance planning was needed. For instance, I won’t be harvesting brussels sprouts until October, but for sprouts lining stalks three to four foot tall, I sowed those seeds indoors in March. Celery and celeriac seed got sprinkled in mini-furrows in seed flats way back in early February.

Zero Tolerance for Weeds, Almost

    Almost as important as timing for my fall garden is weeding. The enthusiasm of many gardeners peaks in spring and then slowly wanes as summer heats up. Not mine.
    Every time I see a lambsquarters weed, the thought of the eventual 100,000 seeds it might sow prompts be to bend down and yank it out. Same goes for purslane plants, whose seeds remain viable in the soil for decades. And spotted spurge; each plant not only spreads thousands of seeds, but those seeds sprout quickly to mature new plants that make even more baby, then adult, spotted spurges. How could I bring myself not to pull these weeds. (Yes, I know, lambsquarters and purslane are edible — if you like their flavor.)
    With weeds kept in check through June, much less effort has been needed to maintain the status quo. Mostly, this is because drier weather has limited weed growth and seed germination, and because any watering in my garden is with drip irrigation. Rather than coaxing weed growth in pathways (and also wasting water), as do sprinklers, drip irrigation pinpoints water to garden plants.

Fresh Figs Bring Me back to Summer

    Back to enjoying summer . . . we’ve been enjoying the first crop, known as the breba crop, of figs from the ‘Rabbi Samuel’ fig tree espaliered in the greenhouse.

   Most fruit plants bear fruits on one-year-old, or older, stems. Figs, depending on the variety, can bear on one-year-old stems, on new, growing shoots, or on both one-year-old stems and on new, growing shoots. ‘Rabbi Samuel’, I have found, bears on both.
    The tree is trained to a T, with two horizontal arms growing in either direction from atop an 18” high trunk. New shoots spring up vertically at about 6 inch spacing along the arms. Late each fall, I cut all those shoots almost back to the arms to make room for and coax new fruiting shoots for the following year.

       The stubs left after cutting back the season’s shoots are one year old, and that’s where brebas have been borne. This fall, I’ll leave some a few inches long, for a larger breba crop next July; the next year I’ll shorten them more drastically and leave others a few inches long; and so on, year after year.
    The main crop, on new, growing shoots, should begin ripening not to long after the  last of the brebas have been harvested. With sufficient sunlight and a bit of supplemental heat in the greenhouse, harvest of the main crop will continue until November’s days grow too short, soothing the transition from the summer to the fall garden.

Back to the Future

Time to jump into the future, again. It’s autumn of this year and tomatoes, peppers, cucumbers and other summer delicacies are on the wane. Does the vegetable garden appear melancholy and forlorn? No! It’s lush with savory greens that thrive in that cool, moist weather to come, vegetables such as kale, broccoli, cabbage, radishes, turnips, lettuce, and endive. (Right now I hunker more for tomatoes and peppers than cabbages and turnips but nippy temperatures and shorter days will, I know from experience, bring on the appeal of autumn vegetables.)
Planning and planting need to take place right now in order to realize my autumnal vision. First on the agenda will be sowing seeds of cabbage and broccoli, in early June, not right out in the garden but in seed flats from which, after about a week they’ll be pricked out into individual cells in plastic trays. A little more

than a month after that, the plants will be ready for their permanent home in the garden. That might be where early bush beans or summer squashes had been sown, harvested, and cleared out of the way. The point is that autumn’s broccoli and cabbage plants, although sown in early June, need not take up space in the garden until late in July.

—————————————-
As I wrote a few weeks ago, information on frost dates, both the last spring frost  and the first autumn frost dates — can be gleaned by choosing a state from the website http://cdo.ncdc.noaa.gov/climatenormals/clim20supp1/states/ and then finding weather data for a nearby location. That nearby location for me is Poughkeepsie, NY, for which there is a 50% chance of the temperature dropping to 32°F on October 9th.
I figure when to plant broccoli and cabbage by counting back the number of days these plants need to reach maturity from the average date for the first killing frost. And then I add more days because I don’t want to necessarily wait until that first frost date before I can start harvest.
Not that 32°F. would spell the death knell for broccoli and company. But growth slows dramatically as weather cools and days grow shorter so I like to have my plants pretty much fully grown and ready for harvest before the first frost date. With cooler temperatures, vegetables can sit out in the garden patiently awaiting harvest in good condition. (In warmer regions of the country, vegetable plants will actually grow through winter, making autumn a fine time to sow peas or set out cabbage transplants.)
——————————————
Other vegetables, with different numbers of days needed to reach maturity, need sowing on various dates through summer. Here’s the planting schedule for my zone 5 autumn garden having an early October first frost date (as well as additional planting dates for vegetables of summer); where frost dates occur earlier, push sowing and planting dates the same amount of time earlier, and vice versa for regions with later frost dates:
•June 1: sow broccoli and cabbage in seed flats; sow small amount of lettuce and cilantro in seed flats or in garden;
•June 7: 3rd sowing of corn and 2nd sowing of bush beans in garden;
•June 14: 2nd sowing of cucumbers in seed flats; sow small amount of lettuce and cilantro in seed flats or in garden;
•June 21: 4th sowing of sweet corn in garden; 2nd sowing of summer squash out in the garden; sow small amount of lettuce and cilantro in seed flats or in garden;
•July 1: sow endive and parsley in seed flats; 3rd sowing of beans in garden;
•July 15: sow beets, chard, turnips, kale, and winter radishes in garden; sow Napa-type Chinese cabbage in seed flats;
•August 1 – September 1: multiple sowings of spinach, small radish varieties, mâche, arugula, mustard greens, and pac choi type Chinese cabbage in garden (early sowing will likely bolt but later sowings will press on late into autumn); keep planting lettuce.
All plants growing in seed flats are transplanted out to the garden as soon as they begin to grow too big for the flats, which is typically four to six weeks after seeds are sown.

Multiple plantings of bush beans and cucumbers are ways to keep ahead of bean beetles (yellow, with dark spots) on the beans and striped cucumber beetles (yellow, with dark stripes) on the cukes. It takes awhile for new plantings to get attacked, and that attack is mitigated by whisking the old plants, with potential attackers still feasting, out of the garden to the innards of the compost pile. Multiple plantings also help with summer squashes’ squash vine borers, evident from wilting leaves and a sawdust-like frass that oozes out of stem, although I’m usually glad to be rescued from excess-squash-syndrome by the time the borers take plants down.
The above schedule omits a few vegetables. Carrots: I don’t grow them, but if you do, July 15th is the date to plant them around here. Some people have luck with autumn peas. I don’t because first it’s too hot for them and then it’s too cold for them. Still, if you want to take a chance, sow them August 1st.
And what about rutabaga, parsnip, and kohlrabi? All I can say is, “Yuk!”
