Root vegetables and hearty greens are the stars of the late summer garden, if, of course, you know how and when to plant them. To help you have the most bountiful (and delicious) garden possible, we’re presenting a few tips for eight of our favorite seasonal foods. With this guide, you’ll make the most of your cool-weather growing season, and hopefully have a great fall harvest! For more information, check out websites such as The Old Farmer’s Almanac, which is a great resource to find your region’s frost date, which vegetables like your growing zone, growing needs soil types for different plants, and to help you lay out your garden. In the meantime, read on to get your garden growing!
Broccoli is a go-to cool weather crop. Hearty, easy to transplant, and with the ability to handle a range of climates, this green vegetable produces the biggest and best-tasting crop in crisp spring and cool fall temperatures. The fall season is the best for temperate climates to transplant month-old starter plants, as broccoli likes three months before the first frost to get up to full speed. Broccoli will happily survive the first few frosts of the season and will continue to produce small florets long after you harvest the main head. The yellow flowers from the broccoli are edible and make an attractive addition to your plate.
Similar to many leafy greens, kale is one of the most generous and prolific growers in any garden. While kale can grow over the summer, it tends to shrivel during the hottest months and grow to staggering heights in cooler ones. Like broccoli, kale can tolerate some frost and will grow until the ground freezes. In fact, rumor has it that kale tastes sweeter after living through a couple of fall frosts.
Beets are another crop that can be grown almost anytime but love cold weather the most. As soon as you’re confident the temperature won’t go above 75, start planting beets, but if you start from seed, make sure to soak them for approximately two days before planting. Beets grow fast, and the amount of nitrogen in your soil can determine whether you get leafier or rootier crops (both parts of the plant are edible). Plant them in offset rows, replant every three weeks, and enjoy growing them until your first full day below 32 degrees Fahrenheit.
Mid-September is the ideal time for chard … as long as you’re careful to keep it separated from your beets (because above the ground they look alike)! Clip the leaves once they start to approach a foot tall, starting with the biggest leaves on the outside. Chard will produce more leaves after cutting and will keep your salad bowls and stir-fries interesting all season long.
Radishes are the most prolific root crop in a fall garden. They grow fast, can be crowded together, and can be replanted immediately, even as late as October 1 in some regions. Radishes don’t do well in heat, so waiting until September is ideal. After a hefty radish crop, it is best to wait a couple of years before planting them again in the same spot in the garden.
If patience is your virtue, fall-planting garlic will give you an enviable crop next summer. Garlic is grown from garlic seed or from large sprouting garlic bulbs and will hunker down during winter, freeze in place, and when the ground starts to soften, it will send up shoots, maturing as the days get longer. The best garlic gets a jumpstart in the fall rather than waiting for a spring planting.
Cool soil conditions are the trick for spinach, the most temperamental of all salad greens. Spinach resists transplanting, so it’s best to sow directly into cooler soil, around mid-September, (or early September if you’re in a colder region). Six weeks before serious frost is all it takes for a hefty spinach crop, but spinach will start bearing bountiful leaves before then.
Before it gets too late, sow your carrot seeds directly into the ground. Carrots are best planted by mid-late September and do not transplant well, so sow your seeds directly into the ground immediately! You can get more life out of your carrot season by using a soil cover, which will keep them warm longer, and protect them from the possibility of an invasive carrot-fly attack.
