Bearded flower is cut back in the spring, after the end of permafrost. The end of March – beginning of April, when night temperatures are above 0° Celsius, is the right time for pruning. This promotes new sprouting. The bush forms its flowers in late summer and blooms on this year’s wood. Flower formation is therefore encouraged by a vigorous pruning.

Cut back the bearded flower as early as spring, as long as the weather permits. To do this, follow these steps:

  1. Remove frostbitten branches. Bearded flower can poorly tolerate sub-zero temperatures. Therefore, it may happen that the old shoots freeze in the winter. Cut off the dead parts of the plant down to the green wood.
  2. Check the plant for pests and diseases. If you see signs of infestation, remove all diseased shoots and leaves.
  3. Shorten the other shoots to 20 cm (for particularly fast-growing varieties) and to 15 cm (for slow-growing varieties).
  4. Use sharp and clean pruning shears.

Pruning in March and April will help the plant grow. Pruning in the fall, on the other hand, can harm the plant. It will not have time to recover and may freeze. If you missed the right time in spring, you can only thin out the bearded flower and cut off dead or frostbitten shoots. You can also shorten shoots that have not yet formed flowers to 20 cm above the ground.

Radical pruning in the spring is only an option if the plant is diseased.

The bearded flower is a low-maintenance garden plant with purple-blue flowers. Pruning in spring encourages growth and regular thinning can extend the flowering period. The semi-shrub is then not only pleasing to the eye, but also provides plenty of nectar and pollen for bees in late summer and fall. So if you want to do something good for the environment, you can include the bush in the planting plan for the next garden season. In this way, you create habitat for insects.
