Barrel cacti are popular for their striking appearance and low maintenance. However, over time, they can become overgrown and may need dividing and repotting to stay healthy and look their best. Properly dividing and repotting these cacti ensures they continue to thrive and can even be propagated for new plants.
Tools and Materials Needed
- Sharp pruning shears or a saw
- Heavy-duty gloves
- New pot with drainage holes
- Well-draining cactus or succulent soil
- Talcum powder or cinnamon (for wound sealing)
- Watering can
- Trowel or small shovel
Preparing for Dividing and Repotting
Choose a dry day to work, and ensure all tools are sterilized to prevent infections. Wear gloves to protect your hands from spines. Carefully remove the cactus from its current pot by gently tipping it and loosening the soil around the roots.
Dividing the Cactus
If the cactus has developed offsets or pups, these can be separated from the main plant. Use sharp shears or a saw to cut through the root ball, ensuring each division has roots attached. Allow the cut surfaces to callus over for a few days in a dry, shaded area.
Repotting the Cactus
Fill the new pot with well-draining soil, leaving enough space for the root ball. Place the divided cactus or the main plant into the pot, ensuring it sits at the same depth as before. Fill in around the roots with soil and gently press down to eliminate air pockets.
Aftercare
Do not water the cactus immediately after repotting. Wait for about a week to allow any wounds to heal. When watering, do so sparingly, allowing the soil to dry out completely between waterings. Keep the cactus in a bright, sunny location.
Additional Tips
- Use clean, sharp tools to prevent infections.
- Handle the cactus carefully to avoid spines.
- Repot every 2-3 years or when the plant outgrows its container.
- Monitor for signs of pests or rot after repotting.
Dividing and repotting overgrown barrel cacti can be a rewarding process that promotes healthy growth and new plants. With patience and proper care, your cacti can thrive for many years to come.
