Boobie Cactus Care

The Japanese cultivar is an easy plant to care for. As succulent cacti, they can survive a little bit of neglect. But do ensure you meet its watering, soil, and lighting needs, for proper plant growth.

Boobie Cactus Light Requirements

Growing the boob plant in indirect but bright sunlight is ideal. They can grow well in full exposure to direct sunlight too. But do not keep them in direct sunlight for more than 5 hours. 

Over time, they might suffer scorched or yellow stems. Too little sunlight produces a very stunted plant growth. So consider moving them to a place with more light access.

A room with a south-facing window would be great. There it would receive all the sunlight it needs for proper growth. To provide some filter, use a light curtain or cloth. You can also consider moving the plant a few inches from the window.
