February prune for late summer blossom

It is a month which at times can show signs of spring and entice one to partake in some gardening. Indeed, if the weather is genial then February is the ideal month to prune those plants which belong to the RHS category of Group Six pruning.
Essentially, these are the plants which flower late summer to autumn and on the current new seasons stems and growth. 
Examples of plants which adhere to Group Six pruning are:
​

• Spiraea Japonica
• Fuschia
• Caryopteris
• Perovskia
• Buddleja Davidii

​
As these shrubs flower on the same years growth a hard prune is required during the month of February and as in the case of the hardy Fuschias almost down to ground level, this can be extremely therapeutic too for the person who is doing the pruning. Perovskia ‘Blue Spire’ which exhibits a wonderful display of blue-lilac flowers, also known as Russian Sage, will benefit immensely from a hard prune back to its basal shoots. Perovskia thrives in many coastal areas and in many soil types and with aromatic leaves akin to sage and an appearance similar to lavender it makes an excellent low lying hedgerow.

Buddleja Davidii also known as the ‘Butterfly Bush’ can be cut down, using large pruners, to approximately half a metre from the ground, this will encourage upright shoots with a slight arching habit and will be greatly appreciated by the butterflies.

As a rule of thumb for shrubs which adhere to Group Six pruning, cut back the previous years flowering stems to one or two buds from the older framework.

Certain types of Clematis will also be required to have a hard prune in February, this is particularly the case for Herbaceous Clematis, Gypsy Queen and Clematis Viticella. They all flower on the current seasons growth in late summer and if they are not pruned annually the stems will be devoid of flowers and only up high will the flowers grow and most often amongst a tangled mass of growth. It must be noted that Clematis has its own pruning group classification, those which flower in late summer fall into Clematis Group 3, whereas, those which flower in early summer and on older wood or the previous years growth fall into Clematis Group 2. If unsure when to prune, then observe the time of year the Clematis will come into flower.

For the kitchen gardeners, autumn raspberries will fall into Pruning Group Six.

All old canes should be cut back down to ground level in February and the new canes will start to grow in spring and then fruit in late summer. It is important not to mistake summer raspberries for the autumn variety, as they fruit on the previous years canes, which would result in a loss of crop.
