If you don’t prune the buddleia back every year, it will get out of control and look untidy. In addition, the flowers are becoming fewer and smaller. With a correct pruning, which is also carried out at the right time, the plant gets strong, upright shoots, which then become arched. Namely, they produce the gorgeous buds that are purple, pink, rose, or white in color. Buddleia should be pruned back in early spring. Late March/early April is probably the best time for pruning. The new shoots that will soon grow on your buddleia are very hardy and usually not susceptible to frost damage. It is generally better if you prune the buddleia before growth really begins. However, once the new leaves have formed, you can still perform the pruning required.

Cut back the buddleia to about 30 cm from the ground. In a mild spring, shoots can already sprout on the bush. This isn’t a problem, it just means you should prune it back heavily. This will cause the Buddleia to grow many new arching branches that will have larger flowers.

Don’t be afraid to give the buddleia a radical pruning in spring!

Within a few weeks you will have a beautiful arching shrub that will soon grow to around 2 meters in a few months with fresh foliage and lush flowers. Its branches will cascade as mentioned above, making for a pleasant arch. The new main shoots will also send out some side shoots, which will also bloom but have smaller flowers than the main spikes.

Extra tip:

Buddleia bushes behind a large bed can simply be cut back to around 60 cm each year. This has the advantage that flowering stems start higher and you can plant other shrubs and perennials under or near the base.

A rather light pruning in spring will probably not have optimal results
