7 Tips For Buying Closed Terrarium Plants
- Check humidity tolerance: Select plants that thrive in high humidity without rot. Closed terrariums maintain moist air, which suits certain species.
- Match light levels: Choose plants that tolerate low to medium indirect light common in enclosed containers. Bright direct sun can scorch leaves.
- Choose slow growers: Fast‑growing plants overwhelm small spaces quickly. Beginners benefit from plants that maintain manageable size.
- Size compatibility: Select plants that match your terrarium’s interior space. Avoid overcrowding that leads to competition and poor airflow.
- Pair plant needs: Combine plants with similar water and light requirements to keep maintenance consistent. This ensures balanced ecosystems.
- Inspect roots before planting: Healthy roots prevent future stress and reduce transplant shock. Look for firm, white roots when available.
- Avoid chemically treated plants: Residual pesticides can stress terrarium systems. Choose untreated plants to support miniature ecosystem health.
Frequently Asked Questions (FAQs)
