Frequently Asked Questions
How often should I water my indoor cactus?
During the growing season, water only when the top two inches of soil are completely dry. In the winter, you can often go several weeks without giving them a drop. When in doubt, it is safer to underwater than to overwater.
Why is my cactus turning yellow or mushy at the base?
This is a classic sign of overwatering. The roots have likely begun to decay because they cannot breathe in waterlogged soil. You should check the roots immediately and repot the plant in fresh, dry soil if there is still healthy tissue left.
Do indoor cacti need fertilizer to grow?
Cacti grow slowly, so they only need a dilute fertilizer during the active spring and summer months. Use a low-nitrogen formula once a month to support their health. Do not fertilize during the dormant winter period.
Can I keep my cactus in a room without windows?
No, a windowless room is a death sentence for a cactus. If you lack natural light, you must use a full-spectrum grow light to mimic the sun. Without a strong light source, the plant will eventually wither and die.
Should I be worried about the spines on my cactus?
Spines are a natural defense mechanism, but they require careful handling. Use thick gardening gloves or a folded newspaper to grip the plant when repotting. Keep them away from small children and curious pets to avoid painful accidents.
