Feed Trees and Shrubs

Fertilizing trees and shrubs is a necessity, and that includes fruit trees. One of the most significant benefits of fertilizing trees is the preventative maintenance they provide. Landscape shrubs and trees require sufficient energy stores to remain healthy to survive insect and environmental stress. Trees and shrubs are a valuable part of your property, and it is essential to protect your investment. Established trees and shrubs can be easily fed by homeowners using tree food spikes or granular tree food applications. For best results, provide your trees twice yearly, once in early spring and once mid-fall.

What are Tree Food Spikes?

Tree food spikes are the easiest method for feeding established trees. Tree food spikes are compressed cylinders of slow-release fertilizers. Gradually dissolving, tree spikes release nutrients evenly throughout the season. A mallet or hammer can drive These compressed spikes into the ground. In a dry season, using an auger attachment for a drill makes installation more convenient. Once the quantity of tree spikes needed has been determined, drive the spikes into the soil, spacing them evenly near the tree’s drip line. The drip line is the imaginary ring on the ground directly below the outer circumference of the tree’s branches. For small trees and shrubs requiring only one or two spikes, break spikes in half to allow for a uniform distribution pattern.

How Many Tree Food Spikes?

Measure your tree trunk diameter 18 inches from the ground for the most accurate measurement. Bring your tree measurements to the Grass Pad, and our Green Team can help you determine how many spikes or tablets are required for your landscape. Fertilizer formulas are available for evergreen, shade, ornamental, and fruit trees. Also, there are formulas fortified with iron for plants needing iron supplements, such as azaleas, rhododendrons, or chlorotic pin oaks.

Uncle’s Tip: Do not use tree food spikes on newly installed trees or shrubs. Spikes contain fertilizers in amounts not recommended for new trees or shrubs. Use Uncle’s Root Accelerator for the first 12 months for newly planted trees. 


Granular Application Tree Food

Uncle’s Green Love is specifically suitable for trees such as oak that thrive with iron in their diet. Spread granulated tree food over the feeder root zone using a push or hand spreader, or use an auger to drill holes and fill. Green Love is a non-burning bio-solid fertilizer that slowly releases nutrients to feed trees and shrubs for up to ten weeks. Green Love contains a low nitrogen, slow-release fertilizer formula to enhance root establishment, disease resistance, and plant vigor. Use five pounds of Green Love per inch of trunk diameter for established trees.

Also available is Uncle’s Tree Food, a multi-purpose granule tree food. Uncle’s Tree Food is formulated to feed ornamental trees, shrubs, and large shade trees.

How to Fertilize Newly Planted Trees and Shrubs

If you are planting new landscapes, avoid using fertilizer spikes until the plant has been established for at least one year. New plantings require a unique fertilizer formulation to accelerate root development. Uncle’s Root Accelerator is intended for new plantings and is recommended for all trees and shrubs at installation. Applied once per month for the first year, Root Accelerator will ensure transplanting success. Uncle’s Root Accelerator is a liquid-concentrated plant starter fertilizer mixed with water and then poured around the tree’s base or shrub. The liquid is immediately available to the plant, encouraging healthy root growth.
