Prepare Materials:
- A sharp, sterilised knife or garden shears
- Gloves to protect hands
- Fresh potting mix
- Suitable pots for the new divisions
Division Process:
- Step 1: Gently remove the Cast Iron Plant from its pot to avoid damaging the fragile roots.
- Step 2: Identify the rhizomes—horizontal stems from which roots emerge.
- Step 3: With the knife, carefully separate the plant into smaller sections, each with at least one rhizome and several leaves.
- Step 4: Pot each division in its own container with fresh potting mix, firming gently around the roots.
Aftercare:
- Water the new divisions sparingly until they establish—avoid overwatering.
- Place the pots in a location with indirect light and maintain a consistent temperature, away from drafts.
