We planted our Prunus Subhirtella Autumnalis tree about eight years ago and its now 15 feet tall. Suddenly this summer the leaves have all turned brown. Can't see any evidence of pests. Is this due to the drought? All other plants, shrubs and trees still look healthy. What should we do? We've started pouring water around the base of the tree. Will it recover?
