How do you trim and propagate Tropical Pitcher Plant (Nepenthes)?
Snip off pitchers and leaves once they have browned. Cut back long vines to push new basal shoots; the removed stem makes cuttings (the easiest way to propagate).
What problems affect Tropical Pitcher Plant (Nepenthes)?
New leaves without pitchers, or pitchers drying up, from low humidity or light; blackened leaf tips and dying roots from mineral-laden tap water or strong fertiliser; mould and fungal rot in stagnant air and soggy media; aphids, mealybugs, scale and thrips; fungus gnats around damp media.
How do you fix Tropical Pitcher Plant (Nepenthes) problems?
Use only low-mineral water (rain, distilled or RO) and flush the media if tap water was used. Avoid strong mineral fertiliser — growers use a sparse sprinkle of slow-release pellets in the media or occasional organic feed. Improve airflow and drainage; let the surface dry slightly and use sticky traps for gnats.
