Miracle-Gro® Tree & Shrub Plant Food Spikes (15-5-10) are plant fertilizer spikes designed to help trees and shrubs grow plenty of foliage and vibrant colours while promoting strong, healthy growth. These spikes contain essential nutrients that nourish plants both above and below the ground, creating a double feeding action that supports root strength and overall plant health.
The slow-release formula delivers nutrients directly into the root zone over time, helping deciduous and flowering trees and shrubs grow strong throughout the season. Easy to use with no mixing or measuring required, they should be applied once per season in early spring and mid-fall when soil is soft and moist to support consistent feeding.
