Is my newly planted Quercus Ilex dying?
We recently purchased a Quercus Ilex Tree which was seven years old and grown in a pot. It is about 12ft tall. We planted the tree in a square hole and mixed the backfill with slow release fertiliser and bonemeal. We have kept it well watered or at least the rain has until last week when we are on holiday for a week (when it was very hot and suuny), our neighbour watered the tree for us but probably only once. In the seven days we were away about 80% of the trees leaves have turned brown and are falling off but during the same seven days it has produced a lot of very small catkin-type growths. Is the tree dying or will it recover? What can we do to help it?
