Cacti are the survivors of the plant world. Built to endure scorching deserts and long dry spells, these architectural beauties ask for very little and give back so much character. From tiny windowsill globes to towering columns, a cactus is one of the most rewarding plants you can grow, especially if you tend to forget to water.
Light, Water & Soil
Cacti are sun worshippers. Most want as much bright, direct light as you can give them, ideally four to six hours a day or more. A south-facing window is perfect. Without enough light, cacti grow pale and stretched, losing their compact shape.
Watering is where people get nervous, but the rule is refreshingly simple: water thoroughly, then let the soil dry out completely before watering again. During the warm growing season that might mean every two to three weeks. In winter, when cacti rest, you can cut back to once a month or even less.
Soil is critical. Use a fast-draining cactus mix, or amend regular potting soil with plenty of perlite, pumice, or coarse sand. A pot with a drainage hole is non-negotiable, as standing water is the quickest way to lose a cactus to rot.
Common Problems & Fixes
Soft, mushy, or discolored base signals rot from overwatering. Stop watering immediately and, if caught early, you may be able to cut above the rot and re-root the healthy top.
Pale or stretched growth (called etiolation) means too little light. Move your cactus somewhere brighter, though note that stretched growth won't reverse.
Wrinkling or shriveling is a thirst signal. A good soak will plump it back up within a day or two.

A Note on Pets
Cacti are generally non-toxic to cats and dogs, but their spines are the real hazard. A curious paw or nose can get a painful surprise. Place cacti well out of reach of playful pets, and handle them yourself with thick gloves or folded paper when repotting.
When in doubt, keep new plants out of reach of pets and consult your veterinarian.
