WHERE & HOW TO FARM
Where to farm
Desert biome in Don’t Starve: Reign of Giants; cacti are natural plants and cannot be shovel-transplanted.
In Reign of Giants, use Desert Cacti as a seasonal food route that continues during winter. Cacti occur in the Desert biome and cannot be dug up, so the farm is a repeat harvest circuit rather than a transplanted bed. Harvesting costs health, which armor reduces, and the plants regrow after several days; the wiki gives four days normally and three in spring. Cactus Flesh is available in any season, while the flower is a summer-only drop. Keep a reserve of protection and health before harvesting, then collect from known cactus patches on return visits. This guide is RoG-specific: Cactus is not part of the original base game. It adds a named desert plant target to the existing farm and berry routes without promising that a planted plot will function in winter.
