Cactus seed

Cactus seeds are a farming seed that can be used to grow cacti. They can only be planted in the cactus patch found in Al Kharid. They require level 55 Farming to plant. Growth time is approximately 9 hours. Players can harvest cactus spines from the mature plant.

As of 21 August 2012 update, Ayesha will look after your seed for 6 cadava berries. After the completion of the hard Desert Tasks, the cactus patch will always be looked after.

Cactus seeds are dropped by aberrant spectres, cockroach soldiers, Dagannoth (Lighthouse), desert strykewyrms, ice giants, moss giants, ogres, cave horrors and other monsters. They may be a reward for cremating vyre corpses, obtained by pickpocketing a master farmer or bought from the Vinesweeper minigame for 1200 points each.
