Granular and liquid fertilizers each have their advantages and application methods. Granular fertilizers, such as fertilizer spikes or slow-release granules, are typically applied around the base of the tree or shrub, allowing nutrients to seep into the soil as they dissolve. This method is particularly effective for deep root fertilization, as it can reach feeder roots located several inches deep. In contrast, liquid fertilizers can be injected directly into the root zone or applied as a foliar spray for quick absorption. While both types can be effective, the choice between granular and liquid fertilizers may depend on the specific needs of your plants and the timing of the fertilizer application.
Choosing the Right Fertilizer for Your Landscape Plants
When it comes to selecting the right fertilizer for your landscape plants, understanding the unique requirements of each tree and shrub is essential. For instance, nitrogen fertilizer is often favored for promoting new growth in deciduous trees, while evergreen species may benefit from a balanced tree and shrub fertilizer that includes micronutrients. The timing of your fertilizer application is also crucial; early spring and early summer are optimal for fertilizing trees and shrubs as they enter their active growth phases. By aligning your fertilization practices with the growth cycles of your plants, you can ensure that they receive the necessary nutrients to thrive and contribute to the overall health of your lawn.
