Fertilize in Fall for Healthy Trees

Why should you fertilize trees and shrubs? Improve the health and disease tolerance of your trees and shrubs each year by supplementing much-needed nutrients every fall using fertilizer spikes or a root feeder. Shrubs and trees require energy stores to survive the winter and maintain healthy vigor to defend against pests and diseases.

Feeding established trees and shrubs is idiot-proof. Fertilizer spikes are a combination of slow fertilizers compressed to form a spike. These hard spikes can be driven into the ground using a mallet or hammer or after a dry season, using an auger drill makes installation much easier. Do not use fertilizer spikes on newly installed trees or shrubs. Spikes contain fertilizers in amounts not recommended for new trees or shrubs.

A root feeder can also be used to fertilize established trees. Connecting to your garden hose, special water soluble tablets are inserted into the root feeder handle. The attached hollow metal probe is pushed deep into the soil. As water flows through the root feeder, fertilizer tablets dissolve quickly, and nutrients become readily available to the roots. These root feeders can be used for deep watering trees during drought periods.

For newly installed trees and shrubs use Uncle's Root Accelerator containing a special starter fertilizer formula. Uncle’s Root Accelerator is specifically formulated for new plantings and is recommended for all trees and shrubs that have been installed for less than 12 months. Promoting rapid root growth, Uncle’s Root Accelerator, applied once per month for the first year will improve your transplanting results. Uncle’s Root Accelerator concentrate is mixed with water and poured at the base of the tree or shrub.

How much fertilizer will you need? Bring your tree measurements with you and our sales staff can help you determine how many spikes or tablets required for your tree. Fertilizer formulas are available for shade, ornamental and fruit trees. Measure your tree trunk diameter about 18 inches from the base to get the most accurate measurement. Shrubs and multi-stem trees without a main trunk, just estimate their height.
