Deep-root fertilization is beneficial for mature trees, young trees, and shrubs. A comprehensive plant health care program should include tree and shrub fertilization, as it helps promote healthy, resilient plants with improved resistance to pests and diseases. Fertilizing ensures that tree roots have access to adequate nutrients, but these roots must be healthy to absorb the nutrients effectively. 

Several factors can damage tree roots, leading to stress: 

Our typical tree fertilization pattern.

Research and expert opinions agree that maintaining soil fertility is crucial for tree and shrub health. Fertilization improves plant health, often visible in the normal size and color of the tree's leaves. Deep-root fertilization naturally strengthens trees, enhancing their ability to defend against pests and diseases. 

At Owen Tree Service, our ISA Certified Arborists can assess when fertilization is necessary for your landscape. While leaf size or color are clear indicators of plant stress, there are also more subtle signs that suggest a need for fertilization. In areas like Michigan soil pH can be too high for species like Red Maples and Pin Oaks. If you're considering planting these trees, we can perform a soil analysis to determine if adjustments are needed before planting. 

Fertilization benefits a variety of plants in urban landscapes, including shade and ornamental trees, flowering shrubs, fruit trees, as well as deciduous and evergreen plants. Fertilizing before or after pruning can also help trees recover more quickly from pruning cuts. 

Some believe that lawn fertilization will nourish their trees, but this is often not the case. Lawn fertilizers are typically absorbed by the grass and do not reach tree roots.  

Owen Tree Service provides fertilization for individual plants or entire landscapes. We also offer mycorrhizae and root stimulant treatments to support stressed or recently transplanted trees. If soil analysis shows that adjustments are necessary, we can modify soil pH to help Red Maples and Pin Oaks develop healthy, vibrant leaves.
