Salt, herbicide, light deprivation, boiling water, and burning can all help dissolve a tree stump. You can also bury the tree stump in soil or mulch to help it rot naturally. Killing a tree stump prevents future regrowth, but you may also remove it by digging it out or grinding it.

Yes, cutting a tree's roots can cause it to fall, particularly if major support roots are severed. In extreme cases, trimming roots can affect the tree's structure and stability. Many crucial roots are located just below the soil's surface. If you make severe cuts to roots more than 2 inches in diameter, you risk impacting the tree's water flow and its ability to withstand severe winds or storms. Even cutting roots less than half an inch in diameter under or outside the tree's canopy can cut off its water supply, causing it to decline, die, and eventually topple.

You should avoid cutting off the top of mature cherry trees. This process is called tree topping, and it’s not recommended for cherry trees—or any trees, for that matter. Tree topping removes between one-third to half of the length of the tree trunk, resulting in structurally unsound, fruitless suckers. The only exception is for saplings. Young pie, sour, and tart cherry trees that are over 30 inches tall in the fall or winter before the tree blooms can benefit from heading cuts.

In most cases, you should not use a pruning seal on trees after trimming. Applying a sealant can interfere with the tree's natural healing process, and it does not guarantee protection from pathogens. Instead of sealing the cut, the best practice is to support the tree's natural recovery by providing it with plenty of water and a dormant-style fertilizer. However, there are exceptions. Pruning seals may be recommended for very vulnerable species, like elm trees, in areas where dangerous diseases such as Dutch elm disease are prevalent. In these specific situations, the protection offered by a sealant can outweigh its downsides. For advice tailored to your situation, especially after cutting large branches, it is best to consult a local tree trimming professional.
