Preservation Tree Services uses Arborjet to Heal Chlorotic Trees: Before & After

We’ve been talking a lot lately about how the heavy rains have depleted soils of important nutrients; heavy rainfall has resulted in many trees becoming chlorotic. Chlorosis is a condition that results from both iron and nitrogen deficiencies in the soil. Plant leaves will turn yellow, often with green mid-veins. The plants then cannot photosynthesize properly and can go into decline or even die. We’ve been seeing trees all over Dallas and Fort Worth in this very situation.

Dallas Baptist University was seeing chlorosis and other problems on some of their campus trees so they called us in to take a look. The campus trees are an important part of creating a more healthy and beautiful environment for students, so it’s important to keep those trees healthy.

Before and after nutrient injections.

In order to address the specific needs of the trees on the DBU, we asked if we could experiment with some new higher-concentration micro-injections of specific nutrients; DBU agreed. We used the Arborjet injection system to administer the direct injections into their stressed trees. Properly injecting nutrients or treatments into a tree’s vascular system is a much faster way to address a severe disease, pest or nutrient deficiency problem than using a spray or drench. It’s also more environmentally responsible, as no products are applied to the surrounding environment.

We make sure our staff is kept up-to-date on the latest Arborjet treatments.

As you can see in these before and after photos, the trees are responding very well so far to the new customized nutrient injections. Existing foliage has been rejuvenated and the trees have been able to push out new foliage where they’d previously dropped many leaves. We will continue monitoring the trees on the DBU Campus to make sure they are returned to optimum health and beauty.

Because of the continual heavy rains, nutrient leaching from the soil, overly-saturated soil and soil heaving, you should pay close attention to your trees. If you notice heavy defoliation or yellowing foliage in your trees, please call us immediately for a diagnosis and treatment. The earlier we can treat your trees, the better chance they have to thrive. For more information about how this rain soaked spring could be harming your trees, visit last week’s blog post here.
