How to Care for Tetragonia Expansa?
Caring for Tetragonia Expansa is relatively straightforward. Here’s a breakdown of what I’ve learned:
- Sunlight: This plant prefers full sun. It thrives with at least 6 to 8 hours of direct sunlight per day. If growing indoors, place it in a south-facing window where it can get ample light.
- Soil: It’s not too picky about soil but performs best in well-draining soil. A sandy or loamy soil mix works well. Ensure good drainage to prevent root rot.
- Watering: Tetragonia Expansa is drought-tolerant once established. Water it when the top inch of soil feels dry. Avoid overwatering, as it can lead to root issues.
- Temperature: This plant enjoys warm temperatures. It’s hardy in USDA zones 9-11. Protect it from frost, as it can’t handle freezing temperatures.
How to Propagate Tetragonia Expansa?
Propagation of Tetragonia Expansa can be done either through seeds or cuttings:
- Seeds: Start seeds indoors 6-8 weeks before the last frost date. Sow them in a seed-starting mix and keep them warm. Transplant seedlings outdoors once they’re sturdy and after the risk of frost has passed.
- Cuttings: You can also propagate from stem cuttings. Take 4-6 inch cuttings from a healthy plant, remove the lower leaves, and dip the cut end in rooting hormone. Plant the cutting in a moist potting mix and keep it in a warm, bright location until roots develop.
