Product Description
Whether it's a majestic oak, birch or maple providing shade on a summer's day, or a fragrant lilac bush adding colour and scent to your borders, healthy trees and shrubs are the backbone of any beautiful garden — and Devonia's Large Spikes help keep them that way.
Each solid slow-release spike delivers a steady, targeted supply of nutrients straight to the root zone, supporting the structure and seasonal interest that established trees and shrubs bring to a garden.
How to use:
Water well before application and refer to the dosage chart. Using a hammer and a flat surface item, drive the spikes below and level with the soil surface, continue hammering the spike at least two more inches below the surface. Space spikes evenly around the dripline, at least 30 inches from the trunk. Water as usual and repeat every 8 weeks.
