Place it in a location with low to moderate indirect light, avoiding direct sunlight which can scorch the leaves. Water thoroughly only when the soil is dry to the touch, usually every 2-4 weeks. Ensure good drainage to prevent root rot.

How do I propagate Cast Iron Plant?

The Cast Iron Plant can be propagated through division, stem cuttings, or air layering, though division is the most common and reliable method. To propagate by division, carefully remove the plant from its pot and gently separate the rhizomes, ensuring each division has roots and leaves. Plant each division in its own pot with well-draining potting mix.

Creeping Jenny

What are the light requirements for Creeping Jenny?

Creeping Jenny prefers bright, indirect light, but it can tolerate partial shade. In brighter light, the foliage will be more vibrant and the growth will be more vigorous.
