Autumn is an excellent time for planting. The soil temperature remains warm, allowing roots to establish themselves before cold weather arrives. Since the roots don’t have to support new leaves, they concentrate on building their root systems. Roots continue to grow until the soil temperature reaches 40 degrees.
Fall planting also means less watering as the rains begin. And because the soil is usually moist, plants can weather a warm day.
Cooler air also means less moisture loss through the leaves.
The key to successful fall planting, as it is any time of the year, is to keep the roots watered deeply. Dipping the nursery container in a tub of fertilizer water ensures the roots are well hydrated and the fertilizer will provide a healthy start.
