I took the coconut lining out of one basket – the basket that would serve as the “top half” of the sphere.
I left the lining in the other basket – the basket that would serve as the “bottom half.” (I did trim the lining down a bit as it seemed too large). This “bottom half” would contain soil and plants.
Then, just to help with water retention for the plants, I fitted the inside of the coconut lining with a layer of landscape fabric.
I covered the outside of the coconut lining with sheet moss.
