Torch Cactus Care Guide

Taking care of torch cacti is pretty easy once they’ve settled into their environment. Here’s a complete guide to keeping your torch cactus healthy and vibrant:


Give your torch cactus the right amount of sunlight. They like about 6-8 hours of direct sunlight per day. If you’re growing them indoors, a window facing east or south is perfect. If they need a little extra light, you can use fluorescent lights too.


Torch cacti can handle dry conditions, so only water them when the top 2 inches of soil are dry. Make sure not to overwater, as that can cause root rot. Water your torch cactus in the morning so it can dry off before nightfall. When in doubt, it’s better to underwater them. Torch cacti are tough and can handle longer periods of dryness.


Torch cacti don’t need a lot of fertilizer, but it can help them grow and bloom. Use a water-soluble, low-nitrogen fertilizer once a month during the growing season. Be careful not to overdo it, as too much nitrogen can damage the leaves.


Torch cacti prefer well-drained, sandy soil that’s slightly alkaline. A mix of coarse sand, potting soil, and perlite or pumice works well. Make sure the soil doesn’t retain too much moisture to prevent root rot.

Temperature and Humidity

Torch cacti like warm, dry climates. They do best in temperatures between 65°F and 85°F. During winter, keep them around 55-60°F, but not lower than 45°F. Indoors, make sure they’re not exposed to temperatures below 50°F. Torch cacti can handle low humidity, so don’t worry too much about it. Just keep them away from humid places like bathrooms.

Pests and Diseases

Torch cacti are usually resistant to pests and diseases, but they can get mealybugs, aphids, or scale. Check for signs of pests regularly, like yellowing leaves or stunted growth. If you spot any, remove the affected parts and use an appropriate fungicide if needed. Taking good care of your torch cactus will help prevent pests and diseases.


Pruning is important to maintain the shape and size of your torch cactus. Use sharp, sterilized scissors or pruning shears to remove dead, damaged, or diseased parts. You can also do some light pruning to encourage growth and health. Just be careful not to prune too much, as it can shock the plant and slow its growth.

Potting and Repotting

Choose a slightly larger pot when potting your torch cactus to allow for drainage and root growth. Use the well-draining soil mix mentioned earlier. Repot your torch cactus every two to three years to provide fresh nutrients and improve its health. Do this in late fall or early winter while the plant is dormant to minimize shock.

How To Propagate Torch Cacti

You can propagate torch cacti with seeds, cuttings, or offsets.

Seed Propagation

In spring, soak the seeds in lukewarm water for 24 hours. Plant them in shallow trays filled with sandy, well-draining soil. Keep the trays in a warm area, away from direct sunlight, and keep the soil moist. After about four weeks, the seedlings will sprout, and you can transplant them into individual pots.

Offset Propagation

To propagate with cuttings, use sterile scissors to clip a healthy stem from an existing torch cactus. Let the cutting air dry for a few days, then plant it in a well-draining soil mix. For offsets, carefully cut the base of the torch cactus and separate the halves to reveal new offsets. Plant them in individual pots.

No matter which method you choose, make sure your torch cacti get indirect sunlight and well-draining soil. Water them sparingly to avoid root rot.
