They might also be obtained by pickpocketing master farmers, purchasing or stealing them from Olivia's seed stall in Draynor Village, purchasing them from Head Farmer Jones, or occasionally as a reward when running favours for the Wise Old Man. You can purchase up to 500 potato seeds every 4 hours on the Grand Exchange. A nearby gardener will ask for 2 buckets of compost to watch over your growing potatoes. White lilies, which are obtained from full completion of the hard Falador Tasks, will prevent potato disease.
