While you can plant a late planting to the first frost date, it's always best to allow as much growing time as possible. If you missed the spring planting, then calculate which vegetables you can grow now and still have a harvest before the first frost.
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.
Fall is Good for Root Growth
In the fall, the perfect combination of warm soils and milder weather create ideal conditions for newly planted trees, shrubs, and perennials. Warm soil temperatures encourage root growth – more so than in the spring when the soil is still warming up.
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.
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.
The date that your ground actually freezes varies from year to year, of course, and some areas won't have frozen ground at all. If you're unsure, mid-November is a safe planting deadline for nearly everyone. - Get everything in the ground before the ground freezes.
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.
In areas with cold winters, such as USDA Hardiness zones 5 and 6, you'll generally want to wrap up fall planting by late October, and by mid-October in zones 3 and 4. But better late than never!
You can transplant perennials anytime until the ground freezes in the fall, or wait to transplant them in the spring. Fall is an excellent time to transplant herbaceous perennials because your plants will then have three seasons to establish a good root system before hot summer weather sets in next year.
' 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.
Late winter is 4 to 6 weeks before spring thaw begins. This could be any time in January to May, depending on your climate. Use your average last frost date and count back.
It's never too late. It just matters what you put into that garden. It's too late to grow tomatoes in your Chicago garden in September because you'll be getting cold weather soon, but you could still grow carrots, radishes, and lettuce plants.
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.

"Planting trees and shrubs in November allows the plant to weather cooler temperatures while it is going through dormancy and allows some time for root growth before the ground freezes," Weber says. Pretty camillia is among those with "winter interest" that work well for November planting.
RADISHES
Along with carrots and beets, radishes grown in fall have better flavor than those grown in spring. They grow quickly, so you may even have time to succession plant 2 or 3 rounds, planting every 2 weeks.
Look for deals on spring-blooming bulbs, perennials, trees, and shrubs, which can all be planted in the fall, up until your area gets hit with a hard frost. And don't forget your lawn; cool-season turfgrass can be seeded this time of year, too.
