Author TreeNewal Staff

If you’re like most people, you probably think of fertilizing your lawn in the spring. However, did you know fertilizing your trees in the fall is just as important? In North Texas, trees prepare for winter dormancy in the late summer and fall months, meaning they are actively growing and absorbing nutrients from the soil. Fertilizing your fall tree landscape will help your plants stay strong, healthy, and better equipped to handle stressors like pests and diseases. In this blog post, we’ll dive into everything you need to know about fall tree fertilization for North Texas trees. Stay tuned!
TreeNewal’s ISA Certified Arborists specialize in tree fertilization and nutrition and understand how to maximize health benefits for Dallas trees. If you need help with plant health services, tree nutrition, or a tree health assessment, call (817) 592-6846.

Why Fertilize Trees in Fall?

Fall tree fertilization gives your trees essential nutrients to maintain health and vigor during winter. While you won’t see any new growth, tree roots continue absorbing nutrients from the soil, so it’s essential that they have enough resources to sustain them year-round. Trees in forests receive nutrients through fallen leaves and decaying matter, but as homeowners rake fallen leaves, they inadvertently take away organic nutrients gained from decomposition. That’s a big reason why fall tree fertilization is essential in North Texas.

When to Fertilize Flowering Trees

Flowering trees can be fertilized year-round, and some trees need it more than others. Applying a slow-release fertilizer in the fall will help your trees stay healthy during dormant seasons and prepare them for spring growth. Depending on the type of tree, level of maturity, and tree health condition, the fertilizer content, frequency, and timing can differ.
Generally, the best time to fertilize trees in fall is about two to three weeks before severe winter weather. To help determine the exact date for fertilizing shrubs and trees, contact your friendly ISA Certified Arborist at TreeNewal!

Do DFW Trees Need Fertilization?

Since most North Texas soil is alkaline, prone to compaction, and sits on a shallow bedrock of limestone, the competition for nutrients is extremely difficult for native trees. Most trees and shrubs in North Texas will benefit from routine fertilizer, nutrition, and soil conditioning to supplement missing nutrients and organic matter needed for healthy growth.
Additionally, the main element lacking in DFW soil is iron, making chlorosis a significant threat to all Dallas/Fort Worth trees. Iron chlorosis can quickly cause your tree to decline and die if left untreated. Fortunately, fall is the perfect time to treat iron chlorosis on trees!

Which Fertilizer is Best for My Tree?

While there isn’t a one-size-fits-all solution, understanding what micro and macronutrients are lacking from your soil and unavailable to your trees is the first step. An ISA Certified Arborist can conduct soil and foliar analysis to help you determine your tree’s health and recommend fertilizers or amendments that will achieve the best results for your landscape.

What Makes a High-Quality Fertilizer?

It goes without saying that high-quality fertilizers will be your best option compared to generic alternatives. The best fertilizer is one that’s specifically tailored to promote your tree’s health. It’s essential to use a fertilizer that is specifically designed for trees and shrubs rather than household or garden plants. This is because trees have different biological processes and require specific nutrients. TreeNewal’s blended fertilizer is made of the highest quality ingredients and guarantees your trees and shrubs will receive nutrients for up to six months with a single application. Our ISA Certified Arborists can test your soil to determine which nutrients and minerals are lacking or inaccessible to plant roots. After evaluating your soil, a Dallas tree care specialist will perform deep root fertilization using TreeNewal’s blended formula that will effectively promote and maintain the overall health of your tree.

Top tree question: what’s the best fertilizer for oak trees in North Texas?

For Dallas oak trees, fertilizers with nitrogen, phosphorous, and potassium in a ratio of 12-4-8 or 14-2-14 are generally recommended. However, liquid , slow-release fertilizers like TreeNewal blended fertilizer with MitoGrow will be your best option.
