Large flowered clematis prefer a good quality soil with high nutrient levels and a soil which is moist but free-draining. Improve planting holes with at least 2 forkfuls of well rotted manure or garden compost and if you don't have these use a 'Soil Improver' compost. The Improvement material added should be placed under the root of the plant not around it. This encourages the roots to grow downwards and remain deep and cool during summer. If your clematis flowers in May-June(late spring), cut the dead flower heads when they have finished to encourage a second set of flowers to be produced in the late summer and autumn. Be prepared to wait for a couple of years before they will be at their best - Our saying is - 1st year = Roots, 2nd year = Shoots, 3rd year = Flowers!

The good Doctor
This is a simply marvellous plant in my garden and has become a favourite in the family.
My daughter remembers mine so bought one, my ex wife loved it and bought one and when I moved I couldn’t bare to be without ‘The Good Doctor’ in my new garden.
A consistent performer, flowers well a second time if lightly pruned after the first flowers finish.
Likes Tomato Maxicrop.
