Chemical stump removal is a process through which you will be able to deal with the part of a tree that remains after it has been cut down. The stump can be one of the hardest parts of a tree to get rid of, especially when it is a mature tree. Often, the roots of the tree have formed quite a network underneath the surface. If some of these roots are left to sit in the ground, they can create health hazards, especially if they are popping out from the ground in some place. Determining which mode of removal to use is one of the most difficult decisions that you will have to make.
When to Use Chemicals
Let me start off this discussion by pointing out that there removal of tree stumps by using chemicals should only be done by a professional tree removal expert or arborist as they are also known. The chemicals that are used are quite toxic and may be hazardous to you if mishandled. If a professional is not available, then you will need to do it on your own but under strict instructions from the consultant.
Chemicals are usually used in cases where the tree has extensive root systems. For instance, if a tree has a tap root that makes it difficult to dig it up or pull it out using a backhoe. In such a case, using a grinder will only kill the protruding part of the stump but will not remove the root of the tree from the ground. In such a case, you can burn the tree down to its roots, however, you will find that most of the areas have restrictions when it comes to burning. The other option would be to let the tree naturally decompose, which may take up to ten years depending on the size of the tree. In such a case, when the other mores of stump removal would not work properly, then you may choose to use chemicals in the removal of the tree stump.
How Chemicals Work
The chemicals usually work by accelerating the rate of rotting that the stump. The method itself is not a quick fix for the removal of the stumps. The process may take a few weeks and will require some patience on your part as the chemicals continue working. The chemicals themselves are available commercially and range from sulfuric acid to nitric acid and potassium nitrate. These acids usually eat up the wood up ensuring that it rots a lot faster than it would in normal cases. On the other hand, potassium nitrate acts as a fertilizer that will feed the fungi eating the wood. In fact, any of the fertilizers that are high in nitrates would work well in this case.
How to Apply
To start with, the stump itself has to be dead for at least one year. Using the chemical methods on freshly cut stumps may result in an undesired result. First the stump is cut s close to the ground as possible. The stump should be dead for at least a year. Do not attempt to use chemicals on freshly cut stumps. After that you will drill some holes into the remaining part of the stump and pour the sulfuric acid in the holes.
