The ideal depth of a tree notch depends on the tree, but it should usually be between 20% and 25% of the tree’s depth. However, if the tree is leaning towards the direction of the notch, it can be cut more shallowly—at as little as 10% of the depth. When the tree is leaning away from the direction it needs to be felled, you can cut deeper, closer to 30%.

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.

You should plant trees at least 15 to 20 feet away from your house, and more if the tree will grow large and spread its limbs. Trees pose several dangers to houses when planted too close. They can litter the roof with leaves and branches, create fire hazards, make a ladder for larger pests, and even damage the foundation as their roots grow.
