Dappled sunlight will keep your Rhaphidophora Tetrasperma a happy chappy. This guy doesn’t mind the sun one bit so a nice window will do the trick. Just watch out for scorching on the leaves.
So chill when it comes to watering this kid would rather be under-watered than over watered.
If you’ve ever been to Thailand you will know how humid it is there. The homeland of your Rhaphidophora Tetrasperma means your hardy plant is fine without any extra humidity but would thoroughly enjoy some time in the bathroom, in a gang with some other plants or a right good misting.
Back to Thailand, it’s pretty hot there… so keep him warm. Your house is probably warm enough, just keep him above 10 degrees.
Honestly, this guy will be so fine without feeding but if you want him to grow at an astronomical rate and take over your whole house then monthly waterings are fine in spring and summer. Don’t feed him in the winter.
Keep the little beings in your household away from your Rhaphidophora Tetrasperma especially the cats.
