Lots of factors can cause root suffocation. Tree roots frequently suffocate which negatively impacts the health of the tree. I’d like to bring awareness to this issue, so that you can make smart decisions. Tree roots usually don’t get much attention. However, I find them fascinating. Just think, tree roots not only provide nutrients for the tree, but they also hold it upright through all sorts of weather. Read more about some simple things that can help tree roots remain healthy.
Basic Premise for Tree Root Survival
Tree roots need oxygen to survive. Once you understand that simple concept, all of this makes perfect sense.
Soggy Ground Suffocates Roots
Over time, poorly drained soil can cause root suffocation. Tree roots don’t like to be under water. Soggy ground causes a few problems. First, soggy ground fills up the air spaces in the ground. This prevents oxygen from getting to the roots. Second, it causes root rot. We all know that rotting plants do not grow well. Finally, poorly drained soil can cause major shifts in the amount of water available to the tree. Drought may cause more stress to trees who are used to living in a wetter environment. Keeping areas well drained around trees prevents several major problems.
The Impact of Excessive Mulching & Raising the Grade
Excessive mulching can cause root suffocation. Building a thick barrier of mulch may ultimately suffocate roots by blocking air and nutrients from reaching the roots. It is important to be mindful of how much mulch is used to maintain beds under and around trees.
Like excessive mulching, raising the grade under and around trees can cause significant damage. Small feeder roots usually grow close to the top of the soil. If they are covered with a layer of thick soil, you will decrease their ability to get oxygen and nutrients and suffocate them. Be mindful of tree roots when installing new landscape features.
Compacted Ground Does More than Just Suffocate Roots
Finally, compacted soil also suffocates roots. Roots need air pockets in the soil to survive and thrive. Compacted soil removes the air pockets, robs the roots of nutrients, and can destroy fragile surface roots. Plan before starting an addition or landscape project that requires driving under and around tree drip lines. This is especially important for older, mature trees that usually are of value to your landscape. Once the soil is compacted, it is very hard to undo the damage.
