I have a Bird's Nest Fern that came in a 4" round pot. I keep it inside, near but not close to a window. It's been craving water so I popped it out of the pot and saw that it had been potted in what I think is a soilless mix. Not sure if that's the true term, but it's what many florists use. (this was a gift and came for a florist) Could be peat.
So anyway, I want to repot it and have 3 questions.
Should I keep some of the current 'soil' while adding more in a bigger pot? Only thinking it might prevent some shock and my talent for being too rough on roots.
How big a pot can I put this in? (I have all sizes, shapes, etc) Can I use clay or ceramic or just stick with plastic?
What kind of mix should I use? I have good potting soil, perlite, a mix for cactus & succulents, and I think that's it. Also have supplements like earthworm castings, mycorrhizal fungi, etc. Also have compost but think it would be too 'heavy' for a small fern.
Any advice before I dive in and do this?
