Clematis   

Clematis are vines that need a structure to support them, although type 3 may meander on the ground.  They have colourful, interesting blossoms and feathery seed heads.

Types

There are three types, differentiated by what part of the vine their flower stems grow from.  The type of clematis will determine when the plant can be pruned and when to expect flowers. 

Type 1

These early bloomers flower on stems growing directly from the old vines, hence prune after bloom.  This preserves current season's flowers while encouraging growth,which will bear flowers next season.   Simply remove dead and damaged material, and trim back if necessary.

Type 2

These are also relatively early blooming.  The flowers grow on new branches that sprout from the old vines.  Prune in dormancy, very early spring.  Remove dead and damaged material, old flower stems and old leaves.  Trim back as necessary, making cuts just above the side buds.

Type 3

These are late blooming because the flowers grow on entirely new vines.  Like type 2, prune late in the dormant season.  Cut down drastically to a foot or half a foot above the ground.

Favoured growing conditions

Clematis like part sun or sun, organically rich soil that is moist and well drained (adding plenty of compost or manure will take care of  both moisture and drainage), and shading for the roots.  A warmer spot will produce darker coloured flowers than the same plant in a cooler position!

Pests

Clematis are vulnerable to mildew, so try to enjoy the greying of the leaves as a neat garden effect if it happens to yours.

Aphids are ladybugs' favourite food.  You can buy ladybugs at the garden centre and release them.  Lady bug larvae, which look like black and orange aligators eat even more aphids.

Another great way to reduce aphid numbers is to squish them with your fingers, or gently shower them off the plant with a hose.
