Easy to grow and so many varieties to choose from!
Before you get started…
Clematis are one of the most popular garden plants as there are so many different species and cultivars to choose from. To find the right one for you, consider the following:
- Size & habitat
- Planting position
- Flowers- size, colour and time of year
Planting your Clematis
The best times for planting are either Spring (March to the end of May), or early to mid Autumn (end of August to mid-November).
- Before planting, soak your new plant in a bucket of water for about 10 minutes
- Dig a hole that is roughly 45cms in both width & depth
- Lightly fork the sides and base of the hole- this will encourage good root growth
- Back fill the planting hole with a mix of topsoil, a handful of bone meal and multi-purpose compost
- Dig a hole in the planting mix, deep enough to allow the top of the root ball to be 5cms below the soil surface
- Place the plant into the hole, back fill with the planting mix and firm down
Clematis in Containers
Clematis may be grown in containers as long as certain points are adhered to. The most important being the choice of Clematis.
- Choose your Clematis-it needs to be a compact, bushy and free flowering variety. The early large flowered hybrids are ideal for this (i.e group 2)
- Pick your pot- Plastic pots will not be able to keep the roots cool in summer or warm in winter, therefore it is best to stick with wood, stone or terracotta. Also consider size-ideally it should be no less than 45cm deep and 40cm across as well as having good drainage holes
- Place 6cm of pebbles over the drainage holes, then cover this with a thin layer of pea gravel
- Raise the pot off the ground by using pot feet
- Fill the pot with a 50/50 mix of John Innes No.3 and Multi-purpose compost- each Spring replace he top 6cm with fresh compost
- Plant the Clematis into the pot as described earlier
If plants are to be grown up a wall, a cane is required to support the stems to the trellis or wires. Alternatively, for a free standing plant, use 1.8m canes as wigwam. New shoots need to be trained around the wigwam, not straight up the canes. By starting as low as possible this will ensure flowers all over and not just at the top.
Watering & Feed
Lots of water will be required during the growing and flowering season. If not enough water is given, flower buds will not develop.
Liquid feed with ‘Miracle-Gro’ up to and after flowering. Never liquid feed a dry plant as this will burn the roots!
For containers- use an obelisk as the support and train the stems around it rather than straight up, the resulting display will be much bolder.
Don’t feed with liquid fertiliser when it is flowering as this will shorten the flowering period.
