After planting the sapling in a hardwood tree patch and waiting for it to fully grow, which takes 4,480 minutes (74.6 hours), the plant will grow into a teak tree which can be cut to yield teak logs (and grant Woodcutting experience). Planting the teak sapling yields 35 experience, and checking the health gives you 7,290. When cut down, the tree will automatically regrow after a period of time. A squirrel will look after a player's teak tree in exchange for 15 limpwurt roots. Teak seeds are also a drop from the Windertodt supply crates.
