Fertilize Lawns, Trees, Shrubs

Established lawns, trees, and shrubs will appreciate fertilizer while they are making their new spring growth. I have learned from experience that trees and shrubs do very well with lawn fertilizer, so I use the same fertilizer for all of them. However, if you have broadleaf weeds in your lawn, use weed and feed. Do not apply weed and feed to trees and shrubs, and be careful to keep it off the leaves of all ornamental plants because it will damage or kill them, just like the weeds. I like to use lawn fertilizer which contains some coated or slow release nitrogen because its effect lasts much longer. Organic fertilizers are also long lasting.
