Fall can be the perfect time to suggest the addition of new trees or shrubs to clients. There are a host of reasons contractors can cite to convince clients that fall may be the best season to plant, surpassing even the spring. January through March may be the most popular time for planting, but the fall months of September through December have distinct advantages. Plant roots grow anytime the soil temperature is 40 degrees or higher, which may occur all winter in the southern sates. During the winter months, the roots systems of the fall-planted specimens develop and become established. When spring arrives, this expanded root system can support and take advantage of the full surge of spring growth.
Fall Plants by Region
Fall Planting Advantages Contractors can state the following facts to help clients decide to hire now rather than to wait for spring.
Earlier Bloom Like fall-seeded lawns, fall-planted wildflower seed has a chance to "settle" into the landscape during the winter, and is all ready to burst into growth in early spring. This is why fall-planted wildflower seed is up and in bloom about two weeks earlier than spring-planted seed.
More Time In Fall In the fall, the contractor has far more time to get the work done. And this works in two ways. There is a longer period and far more "good days" for planting in the fall than during the tricky weather in spring. And secondly, contractor has more time during the fall than during the spring rush to get everything done after winter.
Easier Weed Control, Too Fall planting is done after the growing season has ended. That means any weed seed in the soil is dormant, unlike in spring when it's highly energized and just bursting to grow.
Time For Pre-Emergence Advise clients that now is the time to apply pre-emergence, as it must be applied before emergence of winter weeds. Pre-emergent herbicides provide control for: Carpet burweed, chickweed, henbit, clover and many more. For control of spring and summer weeds, a second herbicide application should be applied around February 15th.
