I inherited a very large glass rounded blown glass bottle with a thin neck / opening from my grandmother who was a keen gardener. It's about 2ft diameter and knee high.
I think it's called a carboy?
It's been sitting in the middle of one of my beds and is quite a nice decorative feature, however someone did mention to me that I might be able to grow a bottle garden
Does anyone have any experience or suggestions please?
I'd rather keep the bottle outdoors and I have no plug for the bottle but could make one I'm sure
