September is a great time to think about planting new shrubs and trees in your landscape.

Many experts agree that in the fall, tree and shrub roots are naturally growing aggressively, aided by warm soil and cooler, wetter weather. The cooler temps that fall brings are best for new root growth. Keep newly planted trees or shrubs watered until the ground freezes so they get a good start before going into full dormancy during winter.

Midwest Gardening gives us a few points to keep in mind regarding planting shrubs or trees in September: It is important to allow about six weeks for roots to establish before the ground freezes. For evergreens, allow about eight weeks to establish roots and soak in plenty of water to sustain the needles through winter.

Make sure to water trees and shrubs thoroughly and deeply each week for the first 3 or 4 weeks. Then, back off so the plant can start its’ natural dormancy process. Water evergreens right up until the ground freezes. Evergreens will continue to supply the needles with water until the roots are frozen. If you do plant a bit too late, mulch heavily to keep the soil warm longer. The roots will continue to grow until the ground freezes.

Container grown plants will establish quickly because they have not had their roots disturbed. Balled and burlapped or transplanted shrubs and trees will go through the stress of their roots being cut shortly before the stress of the transplant.

Proper planting and watering are critical if you want healthy, vigorously growing trees and shrubs.

When you plant make sure you add compost, peat and/or composted manure to replace approximately 1/3 of the original soil volume. Never replace all the original soil with black dirt, compost or sand because different soils drain unevenly. For proper drainage, it is important that the soil you use for backfill consists mostly of original soil. Incorporate a root stimulator and a slow release fertilizer at the time of planting as it will help the plant establish quickly and be ready to flourish in the spring.
