This is a special pot where the ferilizer can be tied.
I usually use osmocote as a fertilizer, since it allows me to have the plant for 6 months with fertilizer.
The jar comes with a space to tie the jar to the plant.
this type of procedure is used especially with orchids
the best thing is you dont need supports
Plase if you made and use please put a photo, and put like.
thanks a lot
