Mid- to late-August is often an excellent time to plant fall flowers, as long as the weather isn't still so hot that the plants will suffer heat stress. But don't wait too late to plant, or you'll have a very short window to enjoy your flowers. Check the growing requirements for each plant.
It's not too late to plant in your garden! In much of the country, summer still is full steam ahead in August. In other regions, the hint of cooler evenings mean the growing season is beginning to slow down. But regardless of where you live, there's plenty of time left in the season left for growing things!
Some good candidates to plant now include hydrangeas, daylilies, lilies, sedums, ornamental grasses, peonies, and bearded iris. Just be sure you keep your new plants well watered if the weather is hot and dry. Mulching the beds also helps preserve soil moisture.

August is the perfect time to plant those flowers for a beautiful fall harvest. There are many varieties that can be planted this fall and start blooming early spring.
Vegetables that can be planted in August include leafy greens such as lettuce, spinach, collards, kale and mustard. Radishes, turnips, beets and carrots can all be started from seeds in August.
In fact, many plants — such as spring bulbs and perennials — need to be planted in the late summer or early fall months, depending on your zone, in order to generate enough energy to bloom in the spring. Not to mention, it's never too late to add some colorful annuals to your outdoor space!
You can defy the heat of August and dig in some new garden space for late summer planting. You will certainly appreciate the additional space next spring. Some gardeners may choose container-friendly vegetables for August planting.
Tip. Mid- to late-August is often an excellent time to plant fall flowers, as long as the weather isn't still so hot that the plants will suffer heat stress. But don't wait too late to plant, or you'll have a very short window to enjoy your flowers. Check the growing requirements for each plant.
Answer: Late summer (late August to mid-September) is an excellent time to plant many perennials. It is also a good time to move or divide perennials, such as peony, daylily, garden phlox, and oriental poppy.
Starting too soon can result in a weak, lanky plant, while starting too late can give you one that is just not ready for the outside world—both will struggle to survive!
While spring may be the most common season to tend to your flower garden, that doesn't mean you can't grow something beautiful this fall! August is often the perfect time to start planting because it encourages root growth in the soil before things start freezing, giving your garden a head start for the spring.
Late summer or early fall is an excellent time to plant mums, one of the symbolic flowers of the season. Practically any time in September that strikes your fancy is a good bet, so long as it's at least six weeks before the year's first frost.
Personally I think fall is a terrific time to plant roses. The exception may be if you live well up north where bitter winters come on quick and early, but for most of us it's a good time. Here in our zone 7/6 foothills of the Blue Ridge I start planting in late August when the nights turn cooler.
Meanwhile, summer planting is also not ideal because of the high heat during this season. In San Diego, for instance, the temperature in August can hit 78°F. That's why the best time to plant roses in Southern California is either in spring or fall.
A number of fast-growing summer veggies and herbs can still be planted in July and August. If you have an open spot in your garden due to a lost crop or the end of a spring harvest, there are a few fast growers that you can plant in the heat of the summer.
Adding new plants to your garden area during hot and dry conditions is not ideal, but it can be successful. The number one thing to remember during hot weather is WATER! Frequent watering will need to be done until the new plants are established.
Late summer and early fall, such as September, is the best time to plant chrysanthemums which are hardy perennials that will grow back each and every year with the proper care. Peonies are also perennials, so after you plant them once in September, they'll come back year after year with the proper care.
Most flowers should be planted after your region's last frost date. Planting flowers in spring is the most popular time, but perennials do fine if planted in early fall in the North and late fall in the South.
The latest time to plant for most vegetables would be the second week in June with a short harvest time. If planting crops that mature within 50 days, you could plant those as late as the last week in June, but keep in mind the weather will be turning cooler, especially at night. Cool crops are best for late plantings.
Planting a Late-Season Garden
But does that mean you've missed your gardening window for the year? Probably not! There are many crops you can plant well into summer (as late as mid-late August) and still harvest a sizable amount of food.
Late summer planting
Choose quick-maturing crops. Spinach, lettuce and greens, beets, carrots, peas, and beans can be sown now. Most seeds will readily germinate in the garden now because the soil holds heat well into autumn; warm soil (in the 70°s) is ideal for seed starting, as long as the weather is not too hot.
