Tree and shrub fertilization provide some of the 17 nutrients all plants need, including nitrogen, phosphorous and potassium. Nitrogen promotes plant growth and is required for virtually every process including photosynthesis. Phosphorous helps the plant transfer energy to different parts of itself, essential for root development and flowering. Potassium works all-around, even increasing stress tolerance. It sounds complicated, but the shrub and tree fertilization experts at Lawn Doctor in Thornton will find the correct combination and ratio of fertilizer nutrients for your plants.
Your landscape has different fertilization needs than even those of your closest Thornton neighbors, so we insist on writing a shrub and tree fertilization service specific to your landscape, which starts with our initial visit. We look at your soil, how much shade or sun it receives, signs of insects or diseases, the types of trees and shrubs, and a wide range of other factors to determine what your property needs and design tree and shrub fertilization program for them.
For most of our tree and shrub fertilization around Thornton, we use a four-visit fertilization process. In late winter, we spray an eco-friendly, non-pesticide targeting insect eggs. In early summer, we spray for mites and aphids that would alternately stunt early season growth. In late summer we spray for insects that are otherwise competing with your plants for nutrients during the hottest part of summer. In late fall, we nourish your plants and provide micronutrients not present in the soil.
