Place your Barrel cactus in full sun near a south-facing, sunny window. More sun exposure encourages indoor blooming.
Water the Barrel cactus once every two weeks during the spring and summer. Reduce watering in the fall to once every four weeks as the plant’s growing season comes to an end.
Keep the indoor temperature for your Barrel cactus between 50 and 80 degrees Fahrenheit ( 10 to 26.6 degrees Celsius). Growth will be optimal if the temperature is kept on the high end of this scale.
Allow the soil to dry completely between waterings to avoid root rot. This cactus requires a well-draining soil.
Propagation of the Golden Barrel cactus is achieved through both seed and cuttings.
Root rot is the most common disease of the Golden Barrel cactus and is caused by overwatering the plant. Cut back on the amount of water given immediately and allow the soil to dry.
