Most types of cactus plants naturally grow in super-dry desert conditions with lots of hot sunshine and low moisture. There are some types of cactus plants that grow in humid rainforests, though. It’s always worth checking what conditions your favourite cactus likes before you buy.

Looking After Cacti

Cacti are low-maintenance. They are adapted to survive on very little water in the harsh heat of a desert. They will be perfectly happy living indoors, as long as they get enough light. They grow slowly, so they won’t need re-potting every five minutes.

To help your cactus plants to thrive, you can buy cacti compost from garden centers. Or make your own, with a mixture of compost and grit or fine gravel (30% grit to 70% compost).
