JANUARY
January is when climbers, shrubs and trees are leafless and in their dormant period and one of the best gardening months for pruning any garden subjects that could cause problems during winter storms and high winds. Wisteria is a good example of a climber that can be pruned now. After flowering the previous season and given a summer pruning it produces long wispy new growths that need to be controlled by cutting back. Either summer or winter pruning and whichever plant or shrub you are pruning the first step is to remove any dead or damaged branches.

Pruning Weigelia
Pruning in January - February
If your Weigela has become too large or too old, rejuvenation pruning is a good option. The best time to do this is January – February, although not in freezing weather.
Rejuvenation pruning completely renews the old shrub over a period of three to five years. This should be done methodically. Decide in advance which branches you want to remove in which year. Start pruning in the heart of the shrub, not on the outside. Select branches divided evenly over the entire shrub and cut these down to a height of about 30 - 40 cm, preferably to just above an outward facing eye.
If you decide to rejuvenate the Weigela in three years, you should remove about one third of the branches in the first year. In the second year, you then remove half the branches that were left the last time, and in the third year the remaining branches can be tackled. In the second year, too, you should in principle prune from the inside of the bush, leaving the outermost branches until the last year.

Pruning in June - July
If you wish, any branches that protrude too far can be cut back in June – July, directly after the Weigela has flowered. This is known as shaping or modelling.
