I've recently planted several small (9cm) clematis in my garden with the hopes I can eventually get them to cover and cascade over a big ugly wall. The varieties I decided on are Montana, Cirrhosa and Armandii (tried to go for year round interest). When I planted them, I gave them all a generous couple of handfuls of vitax organic clematis feed and watered them in with some liquid seaweed.
I wondering what feeding regime I should go with to encourage them to grow quickly and healthy? TIA
