You can remove trees, rocks and plants by:
- Pressing once on the tree, rock or plant which you want to remove.
- Drag the tool to the tree, rock or plant to remove.
- If the tool count shows as 0 then you need to wait until you have collected the tool.
If you can not wait to collect the tool you need you can:
- Buy the tool for the required amount of gems.
- Head to the Social Market and see if another player is selling the tool.
