Clematis Pruning: Nelly Moser (Group 2)

Plants in this pruning group are typically large flowering deciduous hybrids that will flower twice in the year. the first of the flowers will be on the previous season's growth in early summer and the second flush will be late in the summer/autumn on the shoots produced from the current season's growth. If the pruning as carefully carried out the plants can be provide virtually overlapping flowering from early to late summer.

When do they need pruning?

Prune in late winter or possibly in early spring but if the latter, ensure that you do it before the new growth starts.

How should they to be training?

Ideally, the plants should be given a strong trellis or wires to grow up.

How should I prune them?

By pinching out the growing tips of the plant. Be careful though as the new growth is brittle so you need to be careful when tieing the plants in place. As the plant matures, it is desirable to try and create a framework of older stems whilst trying to stimulate new shoots in essence, creating the maximum amount of flowers. The season can be lengthened even further by staggering the pruning of some shoots back to healthy buds later than others.

Generally, these plants can be grown with minimal amounts of pruning however, cutting the plant back every three or four years. If the plant is heavily congested, it can be thinned out by firstly cutting out any damaged or weak growth to healthy buds to the base, or to the base after flowering and secondly thin the stems where there the stems are dense or excessive cutting back to an individual stem or to the point where they appear from the main stem.

If this is done, then the first flush of flowers will be lost but the next flush will generally be increased.
