HOW NOT TO KILL IT
Location – It is a rainforest plant, so keep it in a warm room (60-68F / 16-20C). It needs humidity, so a bathroom can be ideal. Avoid rooms with sudden temperature fluctuations.
Light – Put it in partial shade or bright light. Keep It away from direct sun.
Watering + Feeding – From spring to fall, keep the potting mix (but not wet) at all times. Use distilled, filtered, or rainwater as these plants are sensitive to chemicals added to tap water. Make sure the pot drains well. Water more sparingly in winter. Feed once in spring, summer, and fall.
Care – To maintain humidity, set it on a pebble-filled tray of water, and mist daily. Grouping with other plants will also improve humidity. Wipe the leaves occasionally to keep them free of dust. Repot in spring.
This could be a sign of overwatering. Alternatively, your plant may be too cold or exposed to drafts.
SAVE IT – The potting mix should be moist, but not wet. Water sparingly in winter. Try moving your plant to a warmer, sheltered spot.
