How to Grow Cacti Indoors

Cacti are typically desert-dwelling plants that thrive in dry and hot conditions, but these plants also make excellent indoor houseplants. Cacti are quite low-maintenance and need less care than many other houseplants, making them an ideal plant for new gardeners and a great housewarming gift. The secrets to growing healthy cacti indoors include providing them with plenty of sunlight, not overwatering, and using the right soil.

1. Take a cutting from a healthy cactus. You can grow new cacti from a pup that shoots off of a healthy mother plant. Choose a pup that’s plump, unblemished, and healthy. Gently cut or break off an entire pup from the plant. You can also buy cacti at local nurseries, home stores, and garden centers.

2. Let the wound heal. Transfer the cutting to a sunny windowsill. Lay the cutting down flat and leave it for about two days. This will give the wound time to form a callous. If you don’t let the wound heal before planting, the cutting will likely rot.

3. Select a pot for the cactus. The most important thing to remember when choosing a pot for a cactus is drainage. Find a pot with drainage holes in the bottom that will allow excess water to drain out. Cacti also do well in smaller pots, so choose a pot that’s about twice the size of the plant. You can use clay or plastic pots for cacti. Plastic pots are lighter and cheaper, but heavier clay pots are better for large or top-heavy plants.



4. Fill the pot with a cactus-specific potting soil. Cacti need soil that drains very quickly, so choose a medium that’s specific for these types of plants. For even better drainage, mix two parts of the cactus potting soil with one part lava rock pebbles or pearlite.Cacti that sit in wet soil are prone to fungal and bacterial growth.

5. Plant the cutting in the soil. Place the stem or leaf cutting callous-down in the potting soil. Push the cutting in just deep enough so that it will stand up on its own. Use your hands to gently firm the soil around the cutting to stabilize it.

6. Mist the soil. Moisten the soil to provide the cactus with extra water, but don’t soak the soil. Until roots and new growth start to form, only mist the cutting lightly when the soil feels dry. Otherwise, the cutting may rot.

7. Keep the cutting in a bright location. Transfer the cutting to a windowsill or other area that gets lots of bright but indirect sunlight. Too much direct sun can damage a new cutting. Leave the cutting in this location for a month or two, until new growth starts to appear.
