Do Your Trees and Shrubs Need Fertilizer?

You can tell if your trees and shrubs need fertilizer by looking for signs of nutrient deficiency. If your plants have slow or stunted growth or yellowing or pale leaves, they may not be getting enough essential nutrients. You should also evaluate your soil. If the surrounding soil is sandy or compacted, it may lack the necessary nutrients for healthy plant growth. Performing a soil test can confirm deficiencies and help determine the right type of fertilizer to use.

Tree & Shrub Fertilizer FAQs

Do tree and shrub fertilizers work on other plants?

Tree and shrub fertilizers can sometimes work on other plants, but their effectiveness depends on the nutrient composition and the specific needs of the plants you’re fertilizing. For example, general-purpose fertilizers can be used for lawns, vegetables, flowers, and trees. However, slow-release tree fertilizers may take too long to break down for some of these plants.

Why do trees and shrubs need fertilizer?

Trees sometimes need fertilizer to grow strong roots and resist pests and diseases. While they can survive without fertilization, tree and shrub food will help them along in areas where soil nutrients are depleted. Unlike forest environments, landscaped areas often have nutrient-poor soil.

How often should I fertilize my trees and shrubs?

In most cases, trees and shrubs should be fertilized once or twice a year, but some fast-growing or nutrient-demanding plants may need more frequent feeding. Young trees also need more frequent feeding to establish roots, while mature trees need less. Slow-release fertilizers are great for trees and shrubs, as they’ll last for months without further application.
