Raw potatoes can be picked from fields across RuneScape. Players with level 1 Farming can grow them from seeds. Three potato seeds are needed per allotment. They take 40 minutes to grow, grant 8 experience for planting and 9 experience for harvesting. Up to 10 raw potatoes can be stored in a sack making a sack of potatoes.
There is a potato field northeast of the chicken farm (on the eastern side of the River Lum) and north of Ardougne (north west of the Ardougne lodestone) from which potatoes may be picked, occasionally yielding a potato seed instead.
The farming shops will pay players only a starting payment of 4 coins per potato when none are in inventory, with the price paid gradually decreasing as the store's inventory increases.
Raw potatoes are not edible. However, members can cook them, gaining 15 Cooking experience per potato, and then add various toppings on a buttered baked potato to make it heal much more. Potatoes can only be cooked successfully on a range or in a clay oven. Players can also use the raw potato as an ingredient in stew.
Raw potatoes cannot be eaten anymore after the Troll Warzone update. They were renamed from simply "potato" after the update.
Before the update, if a player attempted to cook a potato on a fire or at the sulphur pit, the potatoes would always burn regardless of Cooking level, resulting in a burnt potato. Attempting to cook a potato with these methods now gives the message "You can't cook that in a fire."
However, it can still be fed to the starving adventurers in the Temple Trekking minigame.
