Whiteberry seeds require 59 Farming to plant, take 2 hours and 40 minutes to grow and yield 78 experience points when planted, 437.5 experience points from checking the health, and 29 experience points per berry picked. The bush can be protected for a payment of 8 bittercap mushrooms. After harvesting the berries, a player can make a very good profit. Each set of berries takes approximately 20 minutes to grow. Profits can be further boosted by the ability of a wolpertinger familiar, using the Summoning skill.
Players are able to get them as a reward from Soul Wars by using the "Gamble" option. This will give them white berries in quantities of fourteen. It is not suggested players use this function to get berries, because it is unlikely you will receive many berries at a time.
Filling a compost bin with 15 white berries will yield 15 buckets of supercompost. However, this is not recommended as pineapples are far cheaper and have the same effect.
