Rejuvenate lavender - how to do it?

Lavender lignifies with age

Lavender bushes have to be cut back vigorously every year so that they keep their compact growth and continue to develop fresh shoots and flowers. If, on the other hand, the plants grow uncut, the lower - older - branches become lignified and the lavender becomes bald. In addition, the bushes literally fall apart and lose their beautiful, bushy shape. Branches that are already lignified do not naturally form new shoots and therefore no more new flowers, and they do not sprout as usual after pruning.

Rejuvenate lavender properly

The only way to prevent the lavender bushes from becoming lignified and thus blanched is to regularly prune the plants. This is especially important because old, poorly cared for lavender is very difficult to rejuvenate. Since it is a subshrub (and not, as some suspect, a perennial), radical pruning will only mean that the plant is very likely to die. Therefore, you should never cut into woody parts, because the bush will no longer sprout from it. All you can do is cut off soft branches and hope that the lavender will sprout again afterwards.

Cut lavender

When cutting the lignified lavender, do the following:

  • Using a sharp and clean tool, cut off any soft shoots by about two-thirds.
  • Never cut into old wood.
  • Exception: You have to remove sick or dead branches.
  • You can also remove individual branches to give the bush a regular shape.

The best time for such a topiary is early spring, before the first new shoots develop. You can do a second cut in summer as soon as the lavender has faded. Then cut the bush back about a third. However, this pruning should not be carried out later than the beginning / middle of August, otherwise the plant will lack the strength for winter.

Tips & Tricks

When pruning in spring, you should make sure that a few centimeters of the shoots including leaves from last year remain. This will make it easier for your lavender to drift through in the new growing season.
