I undersatnd most plants need space between each other - say 30 - 50 cms for Clematis, Roses, Jasmine etc.
I would like to have a bit denser coverage. Would putting a potted clematis for example in between other plants that are in the ground have any problems?
It would surely be using it's own soil from it's own pot so not fighting for nutrients etc?
This would be at the back of a border along a wall where I am trying to screen but the existing coverage is too sparse.
