Plant these in August for a delicious fall harvest and colorful flowers
With high soil and air temperatures and abundant sunshine, August is a key time to plant. Now that spring plantings have largely been harvested, it’s the last chance to plant many herbs, vegetables and flowers to enjoy before temperatures start to drop. Prepare your garden by clearing out spent plants and restoring soil nutrients with compost, then start looking forward to an abundant and delicious harvest in fall and winter. If you’re wondering what to plant in August, we’ve got you covered with a variety of recommendations.

What to plant in August
To ensure success for your crops, direct-sow seeds as early as possible in August. If your frost date is rapidly approaching, look for fast-maturing crops or plant starts instead of sowing seeds. It also helps to choose semi-hardy vegetables that can withstand a light early frost.
Depending on what you’re planting and what U.S. Department of Agriculture growing region you live in, August plantings may be more successful in containers, which can easily be moved between shady and sunny spots as needed. Wherever you’re planting, be sure to spread a thin layer of mulch over freshly turned and watered soil to prevent it from forming a crust, which can stunt sprouting plants and lose valuable water.
Vegetables to plant in August
Warm soil temperatures in much of the country allow for lots of different vegetables to succeed in August. Cucumbers, beets, beans, and leafy greens such as lettuces, spinach and kale can all be started in August to enjoy in fall or even into winter.
If you live in a cooler northern climate, try planting a last round of spinach, carrots or sugar snap peas. Fast-growing vegetables such as radishes are also a good choice if you live in a region where the frost date could occur as early as late August.
Many parts of the country can successfully plant cilantro throughout the summer, while warmer regions can plant basil and dill in August. If you started seeds for Brussels sprouts, broccoli or cauliflower earlier in the year, August is the right time to transplant the seedlings to your vegetable garden.
Flowers to plant in August
Many summer annuals tend to go on sale in August, but that’s because the growing window is closing fast. If you don’t mind only enjoying these flowers for a short time, stock up on petunias, cosmos or geraniums and plant away.
Mums are a popular flower for fall gardening, with blooms starting in September. Marigolds are another popular addition to a home garden, especially if you routinely deadhead them to encourage flowering. Nasturtium, New England asters, snapdragons and sunflowers are all great picks for August planting.
Cover crops to plant in August
If you’re ready to put away the gardening tools and relax for the rest of the summer, consider signing off on your growing season by planting cover crops. These plants, usually a mix of certain legumes and grasses, are great for replenishing nutrients such as phosphorus and nitrogen that have been depleted by the spring and summer growing seasons. They also prevent erosion and weeds.
Depending on your region and your soil needs, try cover crops such as field peas, crimson clover, buckwheat or hairy vetch. Edible cover crops can be eaten, but it’s more common to simply leave them, then mix the dead plants into the soil next spring.
