Welcome Spring!! (At least we hope its spring by now!) I have been looking forward to this since that early snow hit in October last year!
It is time to think about protecting the landscape plants and trees in your yard. If you would like a free evaluation of what trees and shrubs on your property need protected, give me a call! I would love to hear from you. The first application is a Horticultural Oil spray that smothers the pesky overwintering pests and their eggs on your evergreens. This will benefit the Rhododendrons, Spruce trees, Hollies, Pine trees, and Azaleas. Depending on the weather this takes place generally from mid-March through mid-April. Everything is going to be running a bit behind this year though, thanks to Mother Nature!
The next applications should be applied between April and May. These are fungicide applications for the control of apple scab, mildew, rust, and other fungal diseases. As with all things horticultural, the timing depends on the weather and generally requires 2 to 3 treatments for good control. The trees and shrubs that will benefit are crab apples, lilacs, hawthorns, dogwoods, and magnolias.
Another disease that we need to be keeping tabs on is Dutch Elm Disease. With the wet springs and hot & humid summers this disease is making a comeback! If you have an American Elm Tree, I would recommend treating yours to preserve it. The treatment is a trunk injection that stays in the trees system for 2-3 years of control depending on the rate of treatment.
Even though the weather has been harsh this winter, there are some benefits that have come from the extreme temperatures. While some of our pests are resistant to cold, there are others that have felt its effect. Some of the bugs that should be less of a problem are gypsy moths, honey locust, ash tree plant bugs, and eastern tent caterpillar! Unfortunately the Emerald Ash Borer is cold tolerant to about negative 30 degrees, so these destructive little pests will still be going strong. Emerald Ash Borer treatments are becoming more urgent every year as the pest pressure continues to grow; these treatments are done after the soil temperature reaches 45 degrees and continue through about July. Mortality rates in ash trees will be 100% for any trees not treated with insecticide.
If you have Ash or Elm trees on your property or aren’t sure if you do, please contact Independent Tree Service at 440-564-1374, or firstname.lastname@example.org and I would be more than happy to come out and give you a free evaluation.
