Caring for indoor cacti is all about finding the right balance. You need to provide the right light, soil, and water. To keep your indoor cacti thriving, follow these essential tips:

- In winter, water them less, every 2-3 weeks, as they are dormant.
- Don’t let your cacti sit in water, as it can cause root rot and other problems.
Pruning is usually not needed for most indoor cacti. They grow slowly and stay compact. But, if your cactus gets too big or becomes lopsided, you can trim it. Cut off any offsets or excess growth to keep it in shape.
| Cactus Care Essentials | Recommendations |
|---|---|
| Light | Place in the sunniest spot, 3-4 hours of direct sunlight per day |
| Soil | Well-draining cactus-specific potting mix or DIY blend |
| Watering | Water only when soil is completely dry, reduce frequency in winter |
| Pruning | Minimal pruning needed, trim if plant becomes too large or lopsided |

| Facing south for optimal light exposure | Careful management of distance between light source and plants |
“Natural light is beneficial for cacti growth, and light penetration is essential for proper development, especially in terms of spination and flowering.”
