Lavender pruning why is summer pruning necessary tips

Freshly planted lavender usually doesn’t need pruning. However, it’s worth giving it one anyway. This is because you can stimulate growth and flowering. If you wait a year before pruning, individual shoots may become woody.

Young plants that have already been growing in the garden or in pots for a year need pruning after they have faded. Lavender is a vigorously growing plant that quickly loses its shape. You can keep its growth compact by summer pruning. However, do not overdo it and cut back the old shoots only by a third.

Old and partially woody plants can and should also be given a pruning in the summer, preferably before flowering. However, do not cut too deep into the woody shoots. Starting from the woody part, count off three plant buds upward. That’s where you can cut the plant. With any luck, all three plant buds will sprout and form flowers the next year. This is a sure sign that the lavender has recovered.

True lavender pruning tips for spring and summer

The genus Lavandula includes a large number of lavender varieties, which differ in their growth. Accordingly, when pruning each variety, you should pay attention to a few things.

1. lavandula angustofolia: Perhaps one of the most popular varieties of lavender is the true lavender. The half-shrub is strongly branched and has a compact upright growth. It reaches a height of growth of about 50 cm. True lavender begins to bloom as early as May after the Ice Saints. The flowering period ends in July. If you shorten the shoots by a third, the lavender will bloom a second time in late summer. You can give it a pruning at the end of August.

2. lavandin x intermedia: Lavandin or Provence lavender is common in the southern parts of France. It has a slightly branched habit and reaches a maximum growth height of one meter. Its flowering period lasts from July to September. Early September is also the right time for heavy pruning. Due to its height, you should shorten the old shoots up to half.

3. lavandula stoechas: the crested lavender is a semi-shrub that grows around 80 cm high in the home garden. Typical for the Schopflavendel is its compact growth and its beautiful dark purple flowers. This variety comes from Spain and is only conditionally hardy. Therefore, the Schopflavendel is cut only once – after the flowering period. However, you need to regularly cut off all withered and dried shoots. Prune the crested lavender back only if necessary in the fall.

Pruning lavender: Summary

Lavender pruning in autumn tips for amateur gardeners

The most important thing about pruning:

  • You should prune lavender back every year, at least twice, in the spring and summer after it has finished blooming.
  • Depending on the variety, the pruning date also differs. True lavender is cut back by two-thirds in late March, early April. Heavy pruning is then done in August. The lavandin is usually cut back once in April and once in September. Crested lavender is only cut back by one-third in the summer.
  • Regardless of the variety, you should only prune freshly planted lavender in the summer during the first year. From the second year, you can cut the plants twice a year. Old plants that no longer grow and bloom as much, you can cut back vigorously. The best time to do this is in the summer.
  • If you want to dry lavender flowers, then you can cut them off in mid-July. If the plant blooms again at the end of summer you should cut it back in September. If it stops blooming, you do not need to cut it back in the fall.
