Early fall is nature's planting time - so when deciding what to plant in September look to evergreen trees and shrubs. If planted at this time, trees and shrubs will require minimal attention as the roots should take well and establish while the soil is still warm and moist.
Vegetables to plant in September: Beets, broccoli, bush beans, pole beans, carrots, cauliflower, collards, cucumbers, kale, kohlrabi, lettuce, onions (seed & sets), radishes, summer squash and turnips.
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.
Some fast growing fall crops like lettuce and radishes can be planted into late September, but many desirable fall crops like broccoli and carrots need several months of prime-growing conditions to mature before frost and low light levels set in. When in doubt, plant your fall crops a little early.
Why 'September Is the New May' When It Comes to Planting Flowers. Your garden may not be looking Instagram ready at the moment, but don't give up: There's time for more color before the first frost.
Flowers to plant in September
English marigold (Calendula) has deep orange petals, which are perfect for a hot border or for cutting. It's easy to grow – from an autumn sowing it should flower from May. Sow direct into shallow drills or on the surface of moist peat-free compost, in pots.
Think about ways to add color and draw beneficial insects to your fall gardens. Consider planting nasturtiums, marigolds, asters, cosmos, mums, and anemones. Plan out your fall pots and planters. Summer blooms are fading, but there are many opportunities to add color and visual interest to your landscape.
Mid-August to mid-October is an ideal time of year to plant new trees, though, that time frame can be stretched into November and December. To be 100% sure, measure soil temperature early in the morning for a few, consecutive days. If your soil is consistently 50° F or higher, you're good to plant.
You may think it's too late to grow all your favorite vegetables from seeds, but warm May temperatures have made the soil perfect for sowing seeds. Warm soil will allow for fast germination and growing plants! Good choices are summertime kitchen garden staples like squash, beans, cucumbers and melons.
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.
Plants in the Cole or Brassica family are perfect crops you can plant in August. Broccoli, cabbage, cauliflower, kohlrabi, and Brussels sprouts all do very well in the fall.
Planting Trees and Shrubs
September is a good time of year for planting evergreens and conifers. Because the ground still warm after the summer, but also quite moist, which encourages early root growth and, therefore, quick establishment.
Planting these bulbs in fall gives them time to establish roots before they go dormant for the winter. The bulbs can be planted anytime from late September through December, though this varies by location and the type of bulbs you are growing.
Plants like chrysanthemums, nasturtiums and asters are wonderful choices for seasonal planting arrangements. While perennials that will survive the winter are great choices, autumn is also a great time to explore new ideas will short-season annuals too.
From early fall through most of November is one of the best times of year to plant spring-blooming bulbs, cool-season annuals and vegetables, as well as many trees, shrubs, and perennials.
Spirea has summer bloom types that bloom from July to September. It produces clusters of raspberry-rose flowers. Many varieties, such as 'Goldmound,' also offer attractive golden or lime-green foliage. These attractive shrubs are fast-growing and should be grown in full sun for the best flowering results.
The answer is: yes! Roses are particularly well suited to fall planting. They tend to benefit immensely, and you can pay a quarter of the price for plants that you might be charged during the spring.
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.
Spring-blooming perennials, especially in the bare root form, are best planted early in the fall. Planting in the fall while the soil is still warm will give the roots enough time establish properly. This allows the plants to emerge from well established roots, with a stronger start, the following spring.
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.
