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.
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.
Include plenty of late summer flowers in your planting plans to continue the display of colorful blooms well into fall. Often gardens can start to look a little lacklustre later in the summer months when the riot of late spring and early summer choices have faded.
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.
Generally speaking, spring-flowering bulbs should be planted in the fall (a few weeks before first frost), while summer-flowering bulbs should be planted in the spring (a few weeks after last frost).
The hardiest of flowers can be planted as soon as the soil in your garden can be worked, even if it's several weeks before the last frost of the season. For half-hardy flowers, hold off until a couple weeks before the final frost, and for tender flowers, plant when there's no chance of frost for the rest of the season.
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.
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.
October is the season to plant spring-blooming bulbs, wildflowers, and many standard gardening favorites. The flowers that don't blossom this winter can spend the cold season in the ground, strengthening their root systems in preparation for a springtime bloom.
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.
Many perennials are grown from tiny plugs that reach salable size while growing in a pot. Generally, these container-grown plants are excellent candidates for late summer and fall planting in your garden. It's usually best to divide plants shortly after they have finished flowering.
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!
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.
Although each plant's needs may vary and some will be more winter-hardy than others, in general about a month before the last fall frost is sufficient in giving the plant enough time to establish itself and take root.
Gardening in the fall provides a longer period with more 'good' days, as compared to the often tumultuous spring season. Plus, if you plant in fall you'll end up ahead of the game and won't have to rush to get everything done after winter. In fact, a good strategy is to plant perennials when you plant your fall bulbs.
Plant wallflowers, forget-me-not, Bellis, Primula, Viola (including winter pansies) and other spring bedding plants in prepared ground or pots.
Autumn is a great season for annuals, perennials and evergreen shrubs to shine. In fact, some of the most popular flowers, like colorful mums, roses, dahlias, purple pansies and yes, even bright yellow sunflowers all bloom around September and October.
Plant Flowers and Vegetables
If you live in a frost-free region, October is a great time to plant cool-weather flowers and vegetables in your garden. Crops such as kale, cabbage, collards, lettuce, carrots, mustard, onions, Brussels sprouts, cauliflower, beets, and garlic can all be planted in early to late October.
' Waiting until fall can be an issue too. 'If you plant a garden late into the fall, the biggest risk is that the plant won't root into the surrounding soil before winter and will be subject to frost-heaving,' Lindsay explains, 'when the rootball slowly works its way out of the ground due to freeze-thaw cycles.
The general advice for gardeners is to get their crops in the ground by the end of June at the latest, but that doesn't mean you should give up hope now that it's July. There's some wiggle room for planting late in the season, depending on your hardiness zone and how strategic you are about what goes in the ground.
The two major planting periods, however, are spring (March to May) and fall (mid-July to September). The spring plantings are harvested in June and July, while the fall plantings are harvested from October to December.
