August Planting

August is generally thought of as harvest season. Many gardeners are busy canning tomatoes, curing winter squash, and trying to figure out exactly how to use all that zucchini. No matter where you live you can also plant in Agust. Exactly what you can plant when varies depending on your climate.

Below you’ll find a few great varieties for August planting. To find out more specific about your climate and when you should plant check out The Farmer’s Almanac First and Last Frost Date Calculator, our post Everything You Need to Know About Plant Hardiness Zones, or this handy Frost Zone Map from The Spruce.

Cool Climates

In cool climates, August planting can be a challenge. Your area may still be experiencing hot temperatures but won’t be for very long. You’ll need to select varieties with short seasons and some cold tolerance. If it’s still hot in your area these cool-season crops may need extra care to germinate and get started. Be sure to keep them moist and use shade cloth and/or mulch to keep the soil cool if needed. Those in cool climates may also want to consider some form of season extension which is discussed later in this post. Here are just a few good varieties to plant this August.

Warm Climates

Those who live in warmer climates (especially zone 8 and farther south) will be able to plant more heat-loving vegetables in August than you could further north. However, some fall crops like spinach and radishes that are great for cool climates will have trouble germinating in the heat and may need to be planted later. Here are just a few good varieties to plant this August.

Other Plants

There are many other varieties that can be planted in August. Root crops like carrots, beets, turnips and rutabagas are all great choices. You can also look at cold hardy brassicas and greens.

You can also plant or begin planning to add perennials to your garden. Perennials like fruit trees and rhubarb transplants are an excellent way to add to your garden this fall. They should be planted several weeks before the ground freezes so they can get established. Be sure too keep them watered even though it’s cool.

Season Extension

August is also a good time to think about season extension. You’ll be able to grow crops farther into the winter if you can provide them some protection. Depending on your budget you may consider setting up cold frames, low tunnels, or even a hoop house. Cold frames and low tunnels tend to be the quickest and most budget-friendly options. Cold frames can be made from simple materials and like straw bales and old windows and may help you grow cold-hardy greens right through the winter.

Planning and Planting for an Abundant Fall and Winter Harvest

Who wouldn’t want a fall garden abundantly producing cabbages, broccoli, carrots, turnips, parsnips, radishes, bok choi, Brussels sprouts, a wide variety of greens, and even peas? The trick to growing a cool season garden, and setting up the fall garden to continue through winter, is planning and preparation.

Check your understanding of cool-season. When grown for fall, many “cool-season” plants actually need to be sown and transplanted in high summer heat, and some as early as June.

Make room! We start our winter crops in August and September, and those plantings will need to supply us through February! We need lots of space for these plantings, so planning ahead is critical.

Below are our tips for getting the most out of your fall garden.

Choosing the Best Fall Crops for Your Garden

Look for storage varieties: these varieties have been bred to be grown in the fall and harvested for winter storage, or left in the ground to be harvested during thaws. Storage tomatoes can be harvested green to ripen slowly wrapped in newspaper in cardboard boxes; storage beets and radishes grow very large and keep well in the ground or root cellar.

Of course, be sure to choose the crops that you and your family enjoy and that are well-suited to your climate!

Calculating Time to Plant or Sow

Calculate back from your average first fall frost date to determine when to plant fall crops. Add 14 days to the listed days to maturity for your variety to account for the “fall effect” of shortening days and cooler temperatures. For plants with a long harvest period, like a broccoli that will make side shoots for 3 weeks after the central crown is gone, add that time in as well. (This may be as long as a month or more.) Add an additional 14 to 28 days if you will be starting transplants from seed, to account for transplant shock and setback.

For us, this means sowing most broccoli and cabbage in late June, with a second sowing 2 weeks later and often a third that we plan to keep growing under row cover until Thanksgiving or later if the weather is with us.

Sowing seedlings in pots or flats for transplanting out later lets you start your fall garden before space is available in your outdoor garden. Use benches or tables high enough off the ground (at least 3 feet) to deter flea beetles or use an enclosed shade structure.

We sow our fall crops in outdoor seedling beds well-supplied with compost in a location shaded from the harsh afternoon sun. The north side of a stand of corn, caged tomatoes or pole bean trellis makes an excellent choice. Outdoor seedling beds should be covered with thin spun polyester row cover or the newer Protek net row cover to guard against flea beetles and other insects. Summer broccoli and cabbage seedlings are ready to transplant in 4 weeks during the summer. Lettuce and Oriental greens in 2-3 weeks.

Making Space in your Summer Garden

Come summer, it can be tempting to fill every inch of the garden with summer tomatoes, peppers, squash, melons, and more. But even the most densely planted garden will still afford room to plant fall crops. Summer lettuce, green beans, radishes, greens, and root vegetables all yield space by late summer for the fall garden. Beds that were once filled with spring cool-season crops, like peas and fava beans, often rotate best into fall cool-season crops (if they’re not used for late summer successions). Plan for summer cover crops to be ready to turn under in time for fall crops.

When will each spring and early summer crop be finished harvest? You can calculate using the listed days to maturity, but we find that a mid-point check allows us to adjust for weather, later-than-planned planting, early bolting, or unexpectedly extended harvests.

Preparing the Ground for Fall Crops

Caring for the soil is even more important when growing 2 or 3 crops a year in the same area. Generously add compost and any other needed amendments before planting your fall crops. Keep plants growing fast and reduce risk of disease by providing regular and adequate moisture (at least 1 inch each week).

Season Extension

If you’ll be planting in cold frames, under row cover, or in a greenhouse, you can adjust your average last frost date backwards by two weeks or longer when calculating when to plant fall crops.
