Best place for plants

Clematis root 'internodal', they don't root below a leaf joint. I think the idea is you take a long piece (60cm) and wrap it around your hand so that it has multiple breaks, you then set it in compost..................Or, as has already been mentioned, Morrisons can be a good source of plants. I always have a snoop around the plant section when there and usually come away with a couple of 'yellow sticker' jobbies to revive at home.
