Pay attention to healthy plants when buying
Newly purchased lavender plants should be repotted immediately after purchase. The small plant pots are far too narrow for this space-consuming plant and should therefore be exchanged for a larger container as soon as possible. By the way, you should take a very close look at the lavender plants before buying, especially the roots. There should be no yellow or brown spots on the plant, and the roots should appear healthy and strong. Do not be surprised if the newly purchased and freshly repotted lavender lets the leaves hang down, this is perfectly normal. The plant has suffered a shock and must now - literally - gain a foothold again.

- Lavender is difficult to propagate from seeds

Are the location and maintenance correct?
Furthermore, incorrect care measures and an unsuitable location can lead to the lavender hanging. In the worst case - especially if the plants get way too much water - the lavender can even die. For this reason, you should pay attention to the following points with older - newly purchased plants first need a period of acclimatization:
- suitable substrate (dry, airy, permeable, low in nutrients)
- good drainage in the soil so that no waterlogging can build up (especially important for potted lavender!)
- Pot lavender does not have “wet feet”, ie it must not stand on wet coasters
- water regularly, but not too much
- sunny (no shade or partial shade!) and sheltered from the wind
- suitable winter storage (depending on the variety)
Watch out for pests and diseases
Hanging leaves can also be a sign of aphid infestation or a harmful fungus. Aphids are rare on lavender - after all, lavender oil is often used as an effective biological remedy against the beasts - but it can infest already weakened plants anyway. Check your lavender for green aphids, especially in the leaf axils and on the underside of the leaves. They can usually be removed easily with a soft soap solution or lavender oil. If, on the other hand, the lavender is infected with a fungus, only a large pruning will help. But be careful: Do not cut too far into the woody parts, as the plant will then no longer sprout.
Tips & Tricks
If the lavender hangs, however, it is not always due to unfavorable site conditions or incorrect care. Lavandin, a cross between Speik and Genuine Lavender, naturally has a tendency to let its inflorescences droop. So if you can't find a cause for your hanging lavender, but it still continues to grow, then it could simply be the Provencal lavender lavandin.
