[ b][/b] I have had my Arborvitae trees for about 25 years --Now they are turning brown and DYEING --Please help me do not know to do to save the rest of my trees--
Why don't you give us some background. Is this a sudden decline or has something been amiss a little at a time? Has anything changed in the location where it's planted? Digging, construction, flooding, drought... removal of nearby tree, fast-growing nearby tree creating more shade, etc. Have you changed the way you care for them -- applied fertilizer, NOT applied fertilizer, sprayed for bugs, herbicided the surrounding....?
