Yellowing Leyland Cypress
I have some young Leyland Cypress that I put in the ground a year ago. They were teeny tiny (due to limited budget) but grew over a foot in their first year. Just recently (the past two weeks) they started to yellow! I have planted them alternately with Emerald Green Arborvitae which have also slightly yellowed, but not as much as the Cypress. I have looked for signs of canker, but cannot seem to find any - although I might not be entirely sure what I am trying to find. I am wondering if this has anything to do with the ice storm we had in late March. The plants have received adequate water but have not been fertilized. Is there anything I can do to help out my trees? I don't want to lose my growing privacy screen! Help!
