Yellowing Leyland Cypress

Posted by monkton_green MD (My Page) on

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!

Hi up there in Monkton. My guess would be the freeze also if it happened when plants were starting to put out new growth. You might send a foliage sample to UMD ext service. Their number is 800-342-2507. Steve in Baltimore County.

Thanks - I'll see how they manage through May and if they continue to deteriorate I'll send off to UMD. I'm hoping it was just the ice and freezing wind storms!!
