On this page of our FAQ section to Animal Crossing New Horizons we explain how to cut down a tree and also how to avoid such action.
How to cut down a tree?
If you want to get rid of a tree on your island, then there are two ways of doing it. The first solution is to use an axe. You can make by using the flimsy axe. This sharp tool will cut down every tree after three hits.
The second way to cut down a tree, available almost from the beginning of the game (because the recipe for an axe can be obtained after some time) is to use a combo in the form of a fruit and flimsy axe. First, you have to eat any fruit (the effect can be seen in the game interface), and then hit the tree with your flimsy axe. The tree will fall. Also, you will lose the super strength provided by the fruit.
How to remove a tree trunk?
After a tree is cut down, it leaves a trunk - it's worth leaving a couple of those because insects like to sit on them, but if you want to remove such a trunk, you have to equip a shovel and dig it out. Whatever.
How to replant a tree?
Cutting down a tree is not the only solution. You can even replant a full grown trees. All you have to do is eat one fruit of your choice and then dig out a tree by using a shovel. A lucky tree will be stored in your inventory. You can plant it anywhere you want or sell it in the store.
