We planted a 30 foot high Nootkatensis in October and it did fine over the winter. However, now (May), it is showing signs of being in distress. Several lower branches have turned totally brown and there are brown ends to many other branches. The leader is drooping a bit more than normal. There are some branches pointing out towards the sun but most are drooping vertically. I am concerned the tree is dieing. Not sure if I should water more or let it follow the natural cycle for May in the lower mainland. Also not sure if I should feed it and if so what, nitrogen, root starter, etc. I guess we were too ambitious transplanting such a big tree. Help!
