How to Grow Clematis
Clematis has a rich history traced as far back as the 17th century when they were first introduced from China to Japanese Gardens.
In time, selected clematis varieties journeyed to European gardens in the 18th century. They have long been prized for their showy flower displays and are wonderful climbers for trellises, arbors, and companion plants.
There are varieties that naturally work well for groundcovers, carpeting banks, or growing up trees.
Picking a Variety of Clematis
Clematis plants can generally be grouped into two different types; deciduous, those that drop their leaves in fall/winter or evergreen that keep most of their greenery all year long.
In dreary areas of the landscape, evergreen adds an interesting feature come winter.
Deciduous types lend themselves to being paired with great fall colored trees/bark. When selecting varieties eventual size and flower color should be kept in mind.
Choosing the Right Location
Most clematis prefer full sun, however their stems near the ground like some shade. Consider planting some shorter plantings near the base to protect the stems from sun scorch in the summer time. Clematis can flower throughout the spring or summer depending on the one selected.
Garden areas needing color at specific times of the year can benefit from the flower timing chosen. Clematis do best in well drained rich soils and can tolerate a decent range of soil pH.
Planting and Soil Preparation
When planting dig a hole as deep and twice as wide as the pot the plant is in. Additional organic matter can be dug into the soil at this time.
Firm the soil around the clematis and make sure to plant at the same height as in the pot. Use a few fingers to brush extra soil away from the stems.
A 2-3 inch layer of coarse mulch such as bark or wood chips can surround the new plant a few inches away from the center of the plant. Organic nutrients can be supplied once or twice a year for healthy measure.
Clematis can create an attractive low growing sprawl but for upright appeal a strong trellis, arbor, or living structure such as tree trunk need to be nearby.
Clematis vines will naturally wrap their adapted leaves around structures and climb as they go. They can be assisted to wrap around objects as well for desired results.

Most vigorous or early flowering hybrids need very little pruning. In certain situations removing tangled growth is all that is required on C. armandii, C. montana, and C. tangutica species. Early summer, large flowering hybrids that flower on the previous years growth can quickly be pruned for shape when all is dormant. Late flowering hybrid varieties, blooming on the current year’s growth can be pruned back to a set of buds in the fall or winter.
