Essential Tips for Growing Small Cactus Plants in Pots
While cacti are famous for being hands-off, a few best practices will keep your miniature collection thriving year-round:
- Potting Soil: Use a fast-draining cactus or succulent mix to prevent sogginess and root rot.
- Pots with Drainage: Always choose containers with drainage holes; standing water is the enemy of cacti.
- Sunlight: Most small cacti need bright, direct light. South or west-facing windows are ideal.
- Watering: Allow the soil to dry completely between waterings. Water sparingly, especially in winter when growth slows.
- Feeding: Fertilize lightly with a diluted cactus fertilizer during the growing season (spring and summer).
- Air Circulation: Good airflow helps prevent fungal diseases, especially in humid homes.
- Repotting: Small cacti rarely need frequent repotting. Only move to a larger pot when they outgrow their container.
