When it comes to landscaping, newly planted trees should be fertilized lightly until they are well established. This usually takes place after their first growing season. Fast-growing young trees should be fertilized annually to promote rapid establishment. The type of fertilizer is not particularly critical, but it is important to avoid weed and feed products that contain post-emergency herbicides that could harm trees.
For the first few years, it is recommended to not fertilize the tree as the roots need time to stretch and establish themselves first. Fertilizer generally won't help the roots for the first few years. Using mulch is also a great idea when planting trees, as it not only reduces water evaporation from the soil, but it prevents grass from competing with the developing root system of trees and keeps mowers and weeders away from the tender bark of young trees. It is important to eliminate minor branch defects when planting, but to postpone pruning young trees for at least a year.
The best time to fertilize newly planted or more established trees is in late April or early May. As the young tree matures, its roots develop an association with fungi called mycorrhizae that help the tree use minerals in the soil. Trees need nutrients to live and thrive, so soil deficient in one or more nutrients needed for the tree to reach its full potential will be more susceptible to diseases, insect problems and a shorter life than a similar, well-fertilized tree. While plants absorb some nutrients through their leaves, large shade trees are not fertilized with this method. The macronutrients needed by plants to grow include nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and sulfur (S). The need to fertilize a newly planted or more mature tree should only be considered if the growth of the shoots is less than 2 inches or if soil tests reveal a specific nutrient deficiency.
After making sure that the location really works for your type of tree, make sure to plant it at the right depth. The tree's root system can extend a great distance over time, and the tree continues to absorb nutrients when the area around it is fertilized. Fertilizing newly planted trees is an important part of landscaping and can help ensure that your trees reach their full potential. When done correctly, fertilizing can provide your trees with essential nutrients that will help them grow strong and healthy. It's important to remember that fertilizing should only be done after your tree has had time to establish itself in its new environment and should be done in late April or early May.
When fertilizing your newly planted trees, make sure you use a fertilizer specifically designed for trees and avoid weed and feed products that contain post-emergency herbicides that could harm them. Additionally, make sure you mulch around your tree to reduce water evaporation from the soil and prevent grass from competing with your tree's root system. By following these tips, you can ensure that your newly planted trees get off to a great start and reach their full potential!.
