Soil Injected Nutrients
On this portion of The Bark we are going to be discussing the benefits of soil-injected nutrients along with signs and symptoms that you should keep an eye out for on your property. Although pruning is most often thought of to be the best thing for your trees’ health, pruning actually removes live tissue, mildly wounding the tree, which can add stress to the tree. Plant health care and specifically, soil-injected nutrients is a great option for proactively caring for your tree by supplying necessary nutrients not always found, and easily depleted in our urban areas. Surviving and thriving are two very different things when it comes to trees and proactive care will always be better.
As can be seen in our first image below, a tree will have fibrous roots that extend far past the drip line of the tree. When we start to consider the areas we have trees planted in our own yards, it begs to question the feasible space we give our trees and their fragile root zones after we factor in flower beds, sidewalks, driveways, and all of the other hardscapes we have at our properties. Add in soil compaction, dry weather, and reduced root zone, we are handed the perfect storm for a stressed tree.
When our homes are built, we disturb the natural setting of the soil by removing the majority of the organic matter and topsoil. The area is then backfilled with less than desirable substrates and trees planted in these areas are left to fend on their own. Our main priority when supplementing soil-injected nutrients is to begin to fight the downward spiral in health. By supplying the trees and soil with much-needed nutrients directly into the fibrous root zone we can help combat these poor growing conditions and ease the stress burden for our trees and help condition the soil to its historical state. In the picture below, we have our soil injection probe that directly incorporates the nutrient-filled solution into the soil and fibrous roots. This solution of water and nutrients is injected down below the grass roots where it is injected in 4 directions under pressure, helping to alleviate soil compaction and deliver the much-needed nutrients.
Nutrient deficiencies can affect 90-year-old established trees in a residential neighborhood just as much as a recently installed tree on a commercial site. By studying the foliar and soil samples taken from the site, our arborists are able to determine which nutrients are sufficiently depleted from the soil and what to incorporate into the soil. Every tree and every situation can be different, and that requires a custom approach to all trees, using a wide array of organic and synthetic fertilizers instead of a “one size fits all” approach.
