Trees, Shrubs and Conifers: Sulpher coated Urea, Fertilizing Liquidambar Tree, 1 by cnswift

Hi,

I have several liquidambar trees and two are not as healthy as I'd like. I had a consulting arborist come to my home to diagnose what might improve the trees, and he suggested backing off the water and to add fertilizer. He reccommended fertilizing with a product called grow-power plus (5-3-1) which very mild mixed with sulpher coated urea nitrogen. I since have had several people sternly warn against using the nitrogen! Does anyone have any experience with using this on trees? I don't want to burn them, but a nice growth spurt would be great.

The photo is of two trees. The left is in distress, and the right is healthy.

Thanks, Christina
