Cath likes
A sunny spot
Cath will love a partially sunny spot to show off her huge purple flowers.
Moist soil
Cath likes her gritty, well drained soil to stay moist, so give her a little drink if it hasn't rained in a while - just make sure her soil is dry first. Climbing walls is thirsty work.
Pruning
Cut her back to about 30cm in the spring so she can grow big and strong again.
