Yes, when a stump is removed, the roots cannot grow anymore because they need the nutrients supplied by the leaves of the tree. Without the leaves, the roots die. Any stump left on the ground can be fired again after being cut, but an important difference between both processes is that removing the stump from the tree removes both the root and the stump, creating a big hole. On the other hand, when grinding a stump, it is ground and the root is allowed to decay. A cut tree doesn't necessarily mean a dead tree.
Even when the trunk and branches are cut off, many tree species can remain alive in their root systems. These roots send new shoots called root suckers that can perform photosynthesis, carry carbohydrates to the roots and keep the tree alive. To completely kill the roots and prevent future growth of piglets, additional measures must be taken through chemical or mechanical methods. You may not believe it, but a tree can grow back from a stump and become a complete tree. It happens because the roots are still present there.
The only thing is that they are not active. But there may be enough nutrients in them to regrow the tree because of the shoots that stick to the ground. Gradually, tree trunks will begin to recover, depending on how healthy the sprouts are. If left to rot naturally, a large tree stump can take decades to die and decay. In the meantime, it can cause a variety of difficulties, from unsightly suction to trip hazards, sinks and more.
To get rid of this problem, you have three solid and effective options: pulling out the stump with tools; shredding stumps with an easy and quick solution for large stumps; or grinding stumps with a stump grinder. When grinding stumps, it is important to note that some of the root system may remain intact “not visible” under the surface of the lawn. For some trees, this is fine as is and saves you from breaking up an area that is about the size of the treetop. An ancient method of accelerating decomposition of stumps is to cut grooves in them, stack soil on top and cover them with a canvas to promote growth of microbes. If you are thinking of removing a stump on your own, you can rent a stump shredder to break up wood and cut roots. Professional arborists and tree removal companies also have insurance against accidental property damage from tree removal and stump grinding.
If you have removed a diseased or pest-riddled tree, grinding a stump can help ensure that disease or pests do not spread. For those who choose to clean up the mess of stump grinding themselves, it is important that they understand exactly what they agree on. Most problems arise because people misunderstood the nature of equipment used for grinding stumps, process by which it would be removed, disorder of process, volume of debris created or potential post-grinding problems (such as root suckers) that can take years to remedy. To ensure that no new shoots appear even after grinding stumps, use a pruning saw or scissors to cut roots around base of stump. Systemic herbicides can also be absorbed into stumps and travel to roots through vascular transport system located in cambium layer between bark and inner wood of stump. Covering stump with mound of earth and applying nitrogen-based fertilizer can accelerate decomposition of remaining stump and root wood. Many complaints people have with stump grinding are due to fact that they had imprecise or unrealistic expectations of how process would work.
Factors such as diameter of stump, age of tree, type of soil, root system and number of stumps determine cost of digging up stump.
