Old Man Cactus Care 101
Water
The Old Man Cactus requires minimal water. Water sparingly and let the soil dry out completely between watering sessions. Overwatering can lead to root rot. During the dormant winter months, reduce the watering frequency significantly. Ensure the cactus is planted in a well-draining soil mix and a pot with adequate drainage holes.
Light
This cactus thrives in full sun. When grown indoors, it should be placed in a location that receives bright, direct sunlight for several hours a day. If the cactus starts to appear stretched or pale, it might be receiving insufficient light. Consider moving it to a sunnier location or providing supplemental light if necessary.
Temperature
The Old Man Cactus prefers temperatures between 70-100°F (21-37°C). It's heat-tolerant but should be protected from frost. Low humidity levels are ideal, and the plant does not require misting. If kept outdoors in colder zones, consider bringing it inside during the winter or when frost is anticipated.
Fertilizer
During the active growing season (spring and summer), feed the Old Man Cactus with a diluted cactus fertilizer every 4-6 weeks. Avoid over-fertilizing, which can lead to excessive growth and potential nutrient imbalances. Always water the cactus before applying fertilizer to avoid root burn. During the dormant winter months, you can skip feeding.
