Sowing Seeds Mid-August For A Winter Harvest

de cicco broccoli

It’s mid-August already, but there’s still time to sow a number of different vegetables for a winter harvest. If you’re growing your own food for your family or for market, you’ll want to take advantage of the remaining season and get these crops in the ground right away. If you haven’t tried it yet, seize the opportunity and overwinter a bed of vegetables for fresh harvesting all winter. If I can do it, you certainly can!

Aside from temperature, the most important thing to consider when planning your winter garden is day-length. Most plants need at least 10 hours of daylight for active growth to occur. Eliot Coleman dubbed this the “Persephone Days” after the Greek vegetation goddess.

The key is to schedule your plantings so that your crops will be 75% mature by the time the Persephone Period begins. Your day-length will vary depending on where you are, so the point at which your Persephone Period begins will likely be different from mine.

Note: To determine your own Persephone Period check out Johnny’s Winter Growing Guide, where they walk you through how to figure it all out.

Plan Ahead

First you have to decide where you’re going to put these crops. Are they for harvesting throughout the winter? Or are you trying to overwinter them for an early spring harvest? Do you now have empty beds where your spring crops formerly sat? Which beds could be freed up? and which ones will be available once the summer crops have been harvested?

Think about how you’ll protect them from the cold. Do you have a high-tunnel or hoop-house, or are you using low-tunnels? Do you have all the supplies you’ll need? You don’t want to be scrambling for row-cover in the event of an unexpected frost-warning; take advantage of the fall season-extension sale going on right now at Johnny’s Selected Seeds.

If you don’t have a high-tunnel or hoop-house, the low-tunnels are a super easy and affordable option for gardeners and commercial growers. Learn more about using Agribon in the Garden in this article I wrote!

9 crops you can sow mid-August

Now you’re gung-ho to grow! Boo-yeah! But what can you plant this late in the season?

Quite a lot as it turns out.

From Seed:

  1. Beets
  2. Turnips
  3. Carrots
  4. Leeks
  5. Broccoli raab (this is a little different from your typical heading broccoli)
  6. Radishes
  7. Parsley
  8. GREENS: spinach, pac choi, mache, lettuces, mustards, etc.

From Transplants:

I can’t get fall transplants in my area because most folks still garden primarily through the summer around here. If I had started these myself back in July I could have put them in, but by mid-August it’s just too late to try growing these crops from seed. However if you can get them where you are, or if you know a local farmer who grows fall transplants you should totally jump on that and get these crops in the ground. Often people have less trouble with them in the fall because the pest pressure is all but gone and these plants really do like the cool temperatures.

  1. BRASSICAS: broccoli, cauliflower, cabbage (brussel sprouts have a 110 day maturity, so even from a transplant there’s just not time to produce a crop).

Just sow it!

At this point in the season we’re beginning to get worn out, tired from long days toiling in the sun and late evenings in the kitchen preserving the harvest. Yet I know that if you make the effort to get these crops in─come January when you’re harvesting fresh greens for salad or a side of fresh steamed greens─you’ll be glad you did.

Whatever the reason for growing your own food─whether it’s to save money, eat better (as in fewer preservatives, less sugar, less salt, and to avoid cancer-causing pesticides), or to promote a more sustainable food system─you can extend your growing season to extend into the fall and even through the winter with a little strategic planning, and some initiative. So get out there and get those seeds in the ground!

8 tips for growing a fall garden

If you’re as serious as I am about growing your own food you might be considering extending your season with a fall garden. Maybe you’ve never heard of fall gardening or season extension; maybe you think the whole idea is absurd? Here in Maine, many old-school gardeners don’t plant til Memorial Day; they spend their summers in a flurry of harvesting and canning, are done with the garden by October and eat canned or frozen vegetables the rest of the year. If that’s the case you’re missing 3 seasons worth of gardening when you could potentially be producing fresh vegetables to feed yourself and your family. That’s right, you can garden through ALL the seasons with just a little strategic planning.

Extending your season simply allows you to grow more food. It allows you to eat fresh vegetables longer, which is healthier for you because they’re higher in nutrition than canned or frozen foods.  Whether you’re striving to stretch your food budget or working to increase your own self-reliance, a fall garden is going to offer you the opportunity to grow fresh vegetables later into the fall and winter.

Fall Gardening Tips

#1 Know your expected first-frost date: Knowing when to expect that first frost in the fall allows you to determine when to plant a crop─or even if there’s time for a particular crop. If you’ve been gardening for a few years you may already know when to expect frost, but if you’re new to gardening you can ask a fellow gardener or use this free online calculator from the Old Farmers’ Almanac.

It’s important to know the number of days it takes for each vegetable to mature.

#2 Look for days-to-maturity on seed packets: Most seed companies include growing information specific to the breed and variety on the back of the seed packet.  Knowing the days-to-maturity of the crop you are planting allows you to time the sowing of your fall crop. If you can’t find that info on the packet you can usually find it on the seed-company’s website or you can even google the crop to get an idea of when to expect to be able to harvest the crop.

#3 Use a calendar to count back: Take the number of days-to-maturity and beginning on your first expected fall-frost date, count back on a calendar to find out when you should sow the crop.

#4 Utilize free online sowing calculators: There are a number of online calculators you can use to help with scheduling the sowing of your fall garden, including the Fall Harvest Planting Calculator available in the Planning Tools & Calculators section on the Johnny’s Selected Seeds website. These kinds of tools make planning easy and they’re free to use.

These hakeuri turnips are easy to grow and have a short number of days to maturity. One of my favorites!

#5 Select cold-tolerant crops: Some crops thrive in the heat of summer (tomatoes, peppers, squash, etc.), while  others do better in the cooler temperatures of the spring and fall. Typically that’s the roots and greens family, brassicas and peas; that’s a lot of different kinds of vegetables that you could be growing. Check out the selection of recommended varieties for Summer Planting for Fall Harvest at Johnny’s.

#6 Think long-term: Plan your garden strategically, with the intention of following a spring or summer crop with a crop for the fall. For example: I have a bed of lettuces, radishes and turnips I had planted first thing in the spring that is now finished producing those crops. I’ll sow my winter storage carrots there and I can cover them with agribon to grow them late into November.

#7 Keep it moist: Getting some of these cool-weather loving crops to germinate in the heat of high summer can be tricky even to the most experienced growers. Don’t let those beds dry out─maintain consistent moisture levels─and timing a watering around 10 or 11 in the morning can help to keep the soil temperatures low enough that those seeds can take root.

#8 Employ season-extension tools: You can grow so much with just a few wire hoops and a length of Ag-19 row cover for frost protection that it’s well worth the investment. To learn more about using row-cover to extend your growing season check out this article I wrote called: Agribon in the Garden. Watch for Johnny’s annual sale on season-extension supplies to catch a break on the price of the row-cover itself; they usually run that sale beginning in September.

Give it a try!

Just imagine how much more food you could be growing with a fall garden! Whatever the motive behind your garden, it’s easy enough to continue growing fresh vegetables later into the cold season. Why not give it a try and see for yourself?
