Why you need to plant Clematis in early spring

Clematis are the vertical stars of the garden and there's good reason why you need to plant them within the next two weeks

Spring is Clematis time! These versatile climbers are bursting into growth and most are showing new shoots, even though you might not have noticed. Why is this the best time to plant some of these spectacular climbing plants? Because roots will become established relatively quickly in the warming temperatures, meaning you’ll benefit from a whole season’s growth and flowers this year. Plant now and allow your Clematis to become established as the soil warms. It will then be able to give you the full benefit of its imminent beauty. Why wait?

Are Clematis difficult to grow?

A Clematis’ needs are simple. It likes damp, fertile soil and won’t be very happy in anything that resembles a desert. This isn’t difficult and can be achieved by adding organic matter into the hole before planting, then giving everything a good soak. Unlike trees, which can suffer high mortality rates as a result of deep planting, some Clematis like to be planted quite deeply. This applies particularly to the large flowered cultivars that flower on new growth. In Clematis terms this is ‘Pruning Group 3’. Deep planting, maybe with a couple of leaf nodes below the soil level, will encourage lots of stems to be produced, which means more of those large and luscious flowers.

Species vs Hybrids

The species  are those which occur naturally, having not been crossed with other species or hybrids.  They tend to have have smaller, nodding bell-shaped flowers rather than the large and showy hybrids. Having quite a different, fibrous root system, these don't require the deep planting treatment. But all of them appreciate their roots to be in the shade and this can be achieved by using pebbles, mulch or shade-giving materials around the roots on top of the soil. shade the roots, clematis, planting clematis, roots in the shade, gardening, Those Clematis roots need to be kept in the shade. Cover them with pebbles, rocks or mulch after planting

Covering walls, pergolas and trees

If you want your climbers to scramble up pergolas, trellises or trees, make sure you plant in areas of soil that allow rainfall to reach the roots. Avoid planting too close to the base of structures such as walls, or other plants. They will struggle to find enough moisture if they are in competition. Instead, plant about 70cm or so from the tree or structure and train your climber using a cane until it reaches the point where you wish it to climb. clematis, planting a clematis, gardening, Warwickshire Rose, garden, climber, pink flower, Clematis 'Warwickshire Rose' is a great plant for scrambling over a pergola or trellis. But be sure not to plant the roots of any Clematis too close to a wall or tree.

Planting Clematis in pots

You can plant smaller varieties  in pots but use a large container which is at least 45cms in diameter. Root space is vital, and it will need to be fed and watered regularly for prolific blooming. All newly planted Clematis need to be watered regularly until they establish good root systems. A feed is also valuable, choosing a fertiliser specifically to promote flower production and health which will help flower growth.

Pruning groups explained

It’s really not complicated and once you get to know your Clematis you will soon understand why it needs pruning at a certain time. There are three main groups: Group 1: They are early flowering and it stands to reason that the winter and spring flowers appear on last year’s or older growth. These don’t need pruning, except to tidy up damaged stems. These are the species type plants. pruning, clematis pruning, pruning group 1, gardening, pruning, clematis, The species type Clematis with their nodding and bell-shaped flowers generally fall into the Pruning group 1 category.   Group 2: The large, showy Clematis with big blooms need pruning around February. Prune to a pair of healthy shoots and trim away any weak or damaged stems. They should also be pruned again after the first flush of flowers, taking the stems down to the next healthy buds. This will encourage further blooms later in the summer. Alternatively, plants in this group can be left unpruned, then pruned as per Group 3 every three or four years. Clematis 'Multiblue' clematis, climber, pruning group, group 2, gardening, pruning, C. 'Multiblue' is a hybrid with big blooms that falls into pruning group 2. Group 3: These Clematis really do need to be cut back hard in February. This is because they are late-flowering plants that can end up a congested tangle. Cutting back to a strong pair of buds about 30cm from the ground at the beginning of the growing season will encourage lots of fresh new growth. The plant will flower on this new growth later in the year. Clematis Bill MacKenzie, clematis, pruning group 3, gardening, climber, C. 'Bill MacKenzie' will become quite tangled unless it is pruned back near the ground each February. It's a member of Group 3 pruning regime.
