BEST REVIEWED FERTILIZERS 2021 FOR YOUR TREES AND SHRUBS; BUYER’S GUIDE
There are a lot of methods of applying fertilizers to trees and shrubs. This application depends on soil characteristics, site factors, cost, and type of nutrients to be applied. The Liquid soil injection method most often used by professional arborists because it is quick, easy, and also leads to rapid uptake of nutrients. It utilizes high pressure injection of liquid fertilizer into the soil.
The Drill hole method requires drilling holes into the soil and distributing granular fertilizer evenly among the holes. In the Surface application method, fertilizer may be spread by hand or mechanical spreader over the surface of the soil around trees and shrubs.
The surface application method is proven effective in supplying nutrients to plant roots as other techniques. It is particularly appropriate for applying fertilizers to mulched areas and shrub borders. In Fertilizer spikes, solid rods of a pre-measured amount of fertilizer are placed in holes in the soil around woody plants. The rate and frequency of application depends on the general vigor and growth of the plant, with the exception of newly planted trees and shrubs.
Also note that root absorption of nutrients is very efficient in late summer and remains so until soil temperatures approach freezing, therefore trees and shrubs should not be fertilized during times of drought stress or when they are showing signs of water stress unless irrigation is available.
