I have a small roof terrace where i would like to create a foliage screen for privacy.
People have suggested clematis as a good choice as it climbs well.
I am planning to buy the two troughs below
150cm x 15cm x 17cm to be placed against a fence of about 1m heigh on top of which a trelllis that will hopefull have the clematis climbing all over to create the screen.
My main question is will a trough like this be adequate to house a plant that will grow to 2m
Are clematis indeed the right plant, and what sort of spacing between each plant
Im a complete novice so any advice would be much appreciated!
thanks in advance
