vines require an area that will have at least 6 hours or more of direct
sunlight. The plant, depending on the variety, will grow upright six to
twelve feet. However, clematis can only grow as tall as the trellis
arbor or support that you have given it. For example, if your trellis
is eight feet tall and the clematis you choose grows twelve feet, it
would simply hang over and grow down the other side. Clematis roots
need shade to prevent the roots from drying out. Mulching the base of
the plant not only helps to keep the weeds down but more importantly
will keep the moisture in, especially in a hot dry summer.
Moist, well-drained soil is needed. Prepare your hole at least one foot
deep and mix the soil with 50% peat moss or well-rotted manure.
Backfill the hole with the amended soil and plant your clematis or
climbing vine so the top of the root ball is just below ground level
covering the first set of eyes. The plant should be mulched and kept
moist, not wet, especially during the first growing season. Fertilize
every four weeks during the growing season with a well-balanced liquid
main stem of the climbing vine must have firm support, otherwise wind
damage may occur. As the newly planted plant produces new growth, it
should be carefully trained and tied into position.
first year: All newly planted vines should be pruned down to at least
twelve inches the first April-May after planting. This is very
important, and you will be rewarded with a more bushy, compact plant,
full of flowers. If no pruning is done, the plant will still grow and
flower, but you will not enjoy the same display you would if pruning
was done properly.
is a disease that affects large flowering hybrid clematis. It usually
occurs when plants are under extreme stress like hot, dry weather
conditions. Once disease symptoms show (yellowing of the foliage) the
plant will wilt to the ground. Usually, within two weeks, new shoots
appear and the plant will continue to grow. There is no control for
clematis wilt, however it rarely kills the plant. If clematis wilt
occurs, cut back the plant to within twelve inches of the soil and
discard the infected plant material. This disease will spread from
plant to plant so it is very important to discard all infected plant
material. Phyton 27 applied as a drench and reapplied every two to
three weeks as a heavy spray, has been effective in stopping the spread
of the disease. Spraying every two weeks with an all purpose fungicide
such as Clearys or 2Yban are also effective in disease prevention.
is another disease that affects clematis. It is most prevalent in
August when the days are hot and sunny and nights cool and clear.
Spraying plants every two weeks with a fungicide labeled for mildew or
Daconil and 2Yban, will easily control the disease. It may also help to
avoid watering late in the day. Under severe infestations, one spray of
Pipron, followed three days later with Rubigan will clean up the
is another disease that can attack the base of the plant. It occurs
when the foliage remains wet for long periods of time. If foliage is
really dense, it will attack the main stems and the symptoms will
resemble those of clematis wilt. Spraying the base of the plant with a
fungicide labeled for botrytis every two weeks will help in controlling
