The Large Stump is a type of tree. To clear it, you will need to use a Copper or higher quality Axe. Once cleared, you will receive 2 Hardwood. You can find Large Stumps around the Farm and in the Secret Woods.
Six Large Stumps will respawn each day in the Secret Woods, and eight will respawn each day in the Forest Farm. This makes it possible to obtain up to 28 Hardwood each day.
