Keep moist at all times, even newly potted plants. Use large amount of water each time you water.
Intermediate temperatures. Night temperatures for mottled leaf type 65º – green leaf type 60º. The plants can stand temps in the 40’s if necessary (if humidity is kept low and no moisture on leaves) and up to 90º in the daytime if protected against burning. Air movement is essential.
FOOD AND LIGHT
Use a high-nitrogen fertilizer (20-20-20) when potted in fir bark – flush pots once a month with clear water. Need shading from direct sunlight. Medium shade for greenhouse; filtered shade for outdoor culture.
WHEN TO POT
Repot after flowering. Some potting materials good for two years, others only one. Don’t wait until the mix becomes muck.
Use 1/4 inch bark, osmunda or a mixture of leaf mold and redwood fiber. Don’t use crock in bottom of pot. Do not overpot plants – use 4″ to 6″ pots.
