drought stressed apple tree managment?
got some trees (3 year olds) that are dropping leaves presumably due to drought stress. condition is inconsistent with some trees still looking lush and others with dropped leaves. trees are in same area and all have been watered and mulched the same way since planting. no obvious difference (to me, at least) between lush and stressed trees.
1. is such inconsistent response to drought stress typical.
2. will watering after some dropped leaves matter much or are stressed trees done growing for the year?
3. anything I should be doing besides watering.
As always thx in advance for help and advice. Next year (barring another late and untimely frost) I should finally get some apples from my 1st planting in 2009.
