Fall is an ideal time for a number of garden projects. It’s an great time to assess the garden and make any necessary changes. Restoring perennial gardens is a great fall project, particularly when invasive weeds take over or when perennials begin to outgrow their space in the garden. Dividing perennial flowers in to smaller plants can help with overcrowding and help maintain the health of your plants. Fall is also an ideal time for transplanting trees and shrubs.
