Provide cascade palms with indirect light. Direct sunlight can scorch the leaves and cause rapid moisture loss. Locations that receive bright but indirect sunlight for at least half the day are preferred.
Maintain a temperature above 60 degrees Fahrenheit, and preferably between 70 and 80 degrees, at all times. Select locations away from air conditioner vents or drafts because cooler air can damage the palm.
Water cascade palms one to two times a week, or when the soil surface begins to dry but before the soil feels dry beneath the surface. These palms require soil that remains evenly moist with no drying around the root system.
Mist the fronds with water every one to two days to keep the fronds clean and raise the humidity level around the plants. A humidifier may be necessary during dry winter conditions. Grouping several plants together also helps raise the moisture level in the air surrounding the palm..
Apply a soluble tropical houseplant fertilizer monthly during the spring and summer growing season. Apply the fertilizer at half the package recommended rate.
