About This Article
The right way to save a dying cactus depends on its symptoms. If your cactus is shrunken, wrinkled, or wilting, it likely needs more water. Just thoroughly water the cactus until the excess water drains out of the bottom of the pot. Alternatively, if your cactus has segments that are turning brown or black, it could be rotting from overwatering. Check if the soil feels soaked—if it does, remove the cactus from the pot and repot it with fresh, dry soil. If the soil isn’t soaked, let the cactus dry out completely before watering it again, and water it less frequently in the future. Either way, use clean gardening shears or scissors to cut away any rotting segments. If your cactus has pointy tops or stringy stems, that could be a sign that it’s not getting enough sunlight. Move it to a southern- or western-facing window so it gets more light each day. On the other hand, if your cactus is developing yellow or brown spots on the side that’s facing the sun, it could be getting too much direct light. Move it to a shadier spot with indirect sunlight and see if that helps. It’s always a good idea to check your cactus for pests as well whenever it starts to go downhill. Look for mealybugs and spider mites in particular. If you find insects, apply rubbing alcohol to the infested segments with a cotton swab to kill them.
