Plant NOW for All Season Interest!
By Margy Pearl, Extension Master Gardener Volunteer
What do gardeners love about fall? Long comfortable gardening days and sales on a huge variety of attractive, interesting plants. But the most fun thing is adding new plants to our landscape during this season because Fall is the very BEST season to Plant!
Why plant now rather than in the spring? Especially for trees and shrubs, cooler ground temperatures encourage growth and allow time to establish a healthy root system. With a larger root system in the spring, more water can be taken up to survive high temperatures and drought stress. Cooler temperatures now also reduce watering needs and discourage insect pests, diseases, and weeds. No fertilizing is needed since we don’t want to encourage new upper plant growth that could be damaged by harsh winter winds.
What plants will create an interesting all season landscape? Focusing on only shrubs and trees, below is a list of suggestions with plants that are generally more insect and disease free, lower maintenance and includes many natives. Most are either in my yard or on my wish list!
