carnivorous plant soil

Use distilled or rain water rather than tap water. To mimic their boggy habitat, bottom-water by placing pots in a shallow saucer of standing water so the soil can wick moisture up.

Horticultural rice hulls are cited as a sustainable alternative to perlite or vermiculite. These coarse amendments improve drainage and aeration while also contributing some moisture retention.

Closed-top terrariums favor compact, humidity-loving, low-light plants such as mosses, ferns, orchids, and bromeliads. The mixes described are suitable for both closed and open setups.

Thoroughly moisten the mix until it feels wet to the touch before planting. For repotting carnivorous species, use the carnivorous-plant–specific blends mentioned.

Common soilless ingredients include coconut coir (coco coir), pumice, horticultural charcoal, perlite, peat moss, and organic rice hulls. Different mixes combine these components in various proportions.

They combine coarse, soilless components (for example perlite, pumice, and rice hulls) with peat or coco coir so the mix drains quickly and stays well aerated while still holding appropriate moisture.

Moisture-holding ingredients cited include coconut coir (coco coir) and peat moss. These are used alongside drainage components to balance water retention and airflow.

The mixes are described as suitable for humidity-loving terrarium plants such as mosses and ferns and compact low-light species, as well as carnivorous plants like Venus flytraps, sundews, butterworts, cobra lily, dewy pine, and various pitcher plants.
