Dogwood half dead
Just purchased this property, in the front yard is a substantial dogwood tree. Meaning years of growth. Seems that half meaning one side branch appears to be dead. One side had beautiful blooms and the other nothing, now in leaf. I pinched several stems and they broke off easily. Down on the lower part of the trunk it has developed what I'll call suckers. Was going to trim off the dead side but seeing these stems develope not sure if I should wait. The bark on some of the branches is pealing away on the suspected dead side has moss and the white scaly looking algae. Not sure of planting date or care this specimen has received. Knownthe property was vacant for over a year. Any advice beyond amended soil and fertilizer would be appreciated
Thanks for your response to my ailing dogwood. Is it okay to trim off the dead side of the tree at this time, or should I wait till the fall season. If I remember correctly the tree sap is moving upwards feeding the foliage. Your help is greatly appreciated. Thanks in advance. D. Adkins
This time of year (mid-May) is the peak forthe flight time for the female dogwood borer. If you prune the dead branches out of the tree between now and mid-August you should treat the cut surface with an insecticide. The synthetic pyrethroides (or the natural pyrethiums) are the recommended product. Lindane and Dursbane are no longer available but if you still have some you can still legally use these products. They have a longer protection period. Fall and winter are also good times to prune because the borer is not in flight.
William, thanks for you advice, your expertise is greatly appreciated. D Adkins
You are welcome. It is my pleasure.
