Q.What is the normal or average life span of Junipers
Behind our condo there is a row of mature Junipers some may be 6-7 feet tall. They were planted in a tight row to form a barrier to a busy 4 lane road. The one directly behind our condo is about 100 feet from the road. Many are developing brown or dead areas. Is there a way to analyze what is wrong and any possible treatments? They were planted approx in the mid 1980’S. Thanks.
Well cared for Juniper Trees can live 20 years.
Your trees may be nearing the end of their lifespan.
