We wouldn’t recommend it. Topping a tree is very harmful to it. Topping removes anywhere from 50% to 100% of it’s leaf bearing branches. This forces the tree into a state of crisis where it will try and force out new buds to grow leaves for it to photosynthesize. This process requires a large amount of energy and places great stress on the tree. If it doesn’t have enough energy reserves to finish this process, it will become severely weakened, be more vulnerable to pests and diseases, and may die.
We have other ways of making a tree appear smaller with selective pruning, canopy thinning and more which are much safer ways to make a tree appear less prominent.
