Miracle-Gro Tree and Shrub Plant Food Spikes are designed to promote vibrant color and foliage in various trees and shrubs, including arborvitae. These spikes are easy to use, as they are inserted directly into the soil around the tree’s drip line, delivering nutrients straight to the roots. This ensures efficient feed and minimizes wastage.

The recommended application is twice a year, in spring and fall, making it a low-maintenance option for busy gardeners. The product is suitable for deciduous, flowering, and evergreen trees, and it’s especially beneficial for acid-loving plants. This versatility makes it a good choice for a range of gardening needs.

The fertilizer is synthetic, which could be a consideration for those preferring organic options. Additionally, using spikes requires proper spacing to avoid over-fertilizing, which may be tricky for some users. With a package of 12 spikes, it is sufficient for feeding multiple trees or shrubs. This product would particularly benefit gardeners looking for an easy, effective way to nourish their evergreen and other types of trees without frequent applications.

It is also easy to apply, with fine granules that spread evenly across the soil for maximum absorption, which is beneficial for even coverage in larger garden areas.

While it is marketed as suitable for a variety of plants, including evergreens like arborvitae, understanding your soil’s pH is crucial as it does not detail specific pH compatibility.
