Can I use Peters Professional 20-20-20 General Purpose on my evergreen trees?

My 13 evergreen spruce are 10-15' tall and 4 have struggled with rhizophora the last 3 years. I have been using milorganite on them but my arborist suggested a spring application of 20-20-20. Is this appropriate for evergreens and at what percentage? I don't want to do any damage.


Peters Professional 20-20-20 General Purpose Fertilizer is labeled to be used on lawns, platn, shrubs & trees. The label does not specify if Evergreens are included or not. We would suggest contacting the manufacturer directly. Everris can be reached at (843) 760-0679.
