Spoiler alert: Denver is in a desert climate.
We know, it may not seem like Denver is in the desert because there’s limited sand in the Denver area. However, Denver is classified as a high-altitude desert that makes it hard for trees to get all their essential nutrients to thrive. That’s where tree fertilization can help your trees stay healthy and happy.
Types of tree fertilization
Tree fertilization injects a high level of vitamins near the base of a tree’s root system. There are three main practices for applying tree fertilization:
- Root feeding fertilizer – This is where you have seen an arborist hammer a short fertilizer peg into the ground near the base of a tree. This type of tree fertilization of typically applied below the soil surface and often near or beyond the drip line.
- Granular fertilizer – A grain-type fertilizer can be spread on top of the soil around the base of a tree. Granular fertilization typically works best for trees with little to no ground cover or grass. If a tree is more mature, we recommend spreading the granular fertilizer approximately ten feet or farther past the edge of the tree’s canopy.
- Foliar fertilizer – If the name “foliar fertilization” reminds you of the word ‘foliage,’ you’re right! This is a water-based fertilizer that you can spray on a tree or bush’s foliage. One of the common concerns of the foliar fertilization method is that a poorly diluted fertilizer mix that’s too strong or applied too generously can burn a plant’s foliage. Also, if you apply fertilizer in a high level of heat, it can also cause damage to the plant or tree as it sits in the sun.
