The following was received via email: Our back yard is blessed with a 40' to 50' (approx) native dogwood tree. This tree survived the building of our home and subsequent lot grading four years ago and has provided us with the most spectacular display of blooms each Spring and Fall since. This year however, all of the tree's leaves have turned brown at the tips and a lot of them have blown off in the wind. There is an unaffected dogwood tree at the opposite end of our back yard as well as several in the woods directly behind our fence. Could you please give us any information as to why the leaves are brown at the tips as well as any tips that we could use to keep our native dogwood trees healthy and happy? Thank you.
