How to Grow Clematis
by Marilyn Pokorney
Description: How to grow and care for clematis vines.
Clematis is easy to grow and care for and can live for 25
years or more. Clematis is a hardy vining plant that can be
grown from zone 3 to 10.
Clematis should be planted as dormant plants in the spring.
If planting in the autumn do so no later than September so
the plants have a chance to get established before winter.
Clematis should be placed in full sun but a little shade
during the hottest part of the afternoon is appreciated.
To prevent wilt allow for air movement around the plant.
Dig the soil 24 inches deep and two to three feet wide where
the clematis plants are going to be planted. The area
should have good drainage.
Soak bare root plants in water for one hour before planting
to rehydrate them. Plant the roots with the crown one to
two inches below soil level.
Clematis like to have their roots cool. Plant low growing
flowers or a cover crop around them. Mulching can help but
the plants are more susceptible to wilt with mulch than if
partnered with other plants.
Space plants 24"-36" apart. When planting near a fence or
trellis place the plant 12 inches from the base. If
planting by a tree, place the plant three feet from the tree
on the north side. The tree will help to shade the roots.
Clematis needs a deep watering once a week.
Prune clematis plants in the spring or fall. If the
clematis blooms on year old wood, then prune after blooming.
If the plant blooms on new wood, then cut the plant back in
the spring.
New plants can be propagated by cuttings or layering.
Cuttings can take up to 3 or 4 months to form roots.
Layered vines usually produce a new plant after one year.
Clematis can be attacked by a fungus called Ascochyta
clematidina. This causes a wilting of the stem and leaf
spots. Cut back the affected stem below the diseased area.
A new stem will grow from buds on the healthy part of the
plant and the crown underground. Powdery mildew can be
treated with a fungicide as soon as it's noticed.
Slugs, earwigs, and aphids are the only insects that attack
clematis. If rabbits are a problem put a wire fence around
the plant especially for the winter.
