Propagating for terrariums means cheaper restocking, matched genetics to a case that already works, and less pest risk than random shop plants if mother stock is clean.
Best beginner candidates include Fittonia, many Peperomia, Tradescantia (mind vigour), Pilea depressa-types, and some fernlets — avoid slow woody cuttings for first tries.
Do not propagate pest-ridden mothers. Still quarantine if the mother plant’s pest status is uncertain. Some plants are toxic if chewed by pets — label household hazards.
