|When and how do you prune back Weigela|
Named after the German scientist Christian Ehrenfried Weigel (1748 – 1831), Weigela species and cultivars are a genus of hardy deciduous flowering shrubs. Most notable of these are Weigela florida 'Foliis purpureis',Weigela florida 'Variegata' and Weigela praecox 'Variegata', all of which have gained the Royal Horticultural Society's Award of Garden Merit (AGM).

Weigela should be pruned each year directly after flowering. Remove just one or two of the old stems on younger plants and between 10-20% of the old growth on larger specimens. When pruning your chosen stems, remove each one back to ground level.
Under favourable conditions, mature specimens can reach a approximate height and spread of between 2-3 metres. So if you are just want to control their size then cut back by one-third each season. Again this should be addressed immediately after flowering.
On old specimens that are losing their ornamental value, remove no more than one-third of the old woody growth. Repeat this over the next couple of years to effectively rejuvenate the plant. Be aware that such drastic pruning can cause your Weigela to not flower the following year.
