Do not fertilize your trees during the summer, as weak tissue growth will occur and the plant will not harden off properly in the fall. Only fertilize trees if a soil test from a reliable lab indicates a need and then only apply in the spring. Plan to water your trees every two weeks in the fall and every three weeks in the winter unless there is snow on the ground. For more information on tree care visit the section Trees and Shrubs: Maintenance on the public eXtension website.
