How Much Water Does a Coral Cactus Need?

This depends on the season and the size of the plant. Your cactus will need more water during the spring and summer months and less water during the colder winter and fall months. Only water the plant if the soil at the top of the plant is dry.

It is best to water the coral cactus from the bottom and avoid watering the plant directly. Pour the soil onto the soil until it is fully saturated and begins to overflow.

The coral cactus produces a thick white latex sap that is toxic. It may cause skin irritation when touched. Always wear gloves to avoid getting contact dermatitis from the sap. It can also cause nausea and vomiting if ingested. To avoid any potential accidents, place the plant at a height that is unreachable to kids and pets.
