When the lavender turns brown and dies, there are many possible causes. In most cases, these are maintenance errors that must be adjusted accordingly. In addition, the further treatment of the diseased plant depends on the cause, which you should research conscientiously.

Waterlogging causes lavender to turn brown

The lavender usually turns brown and dries up because it was watered too often or incorrectly. Waterlogging due to excess water not draining away in the root area also leads to brown leaves. Lavender is extremely sensitive to humidity and moisture, so waterlogging quickly causes root rot. As a result, the damaged roots can no longer transport enough water to the upper parts of the plant and the plant dries up. By the way, a damp and cool summer can also cause root rot.

What to do with root rot?

If the lavender threatens to die due to root rot, with a bit of luck it can still be saved. To do this, however, you have to dig it out and transplant it or, in the case of potted lavender, convert it to fresh substrate. When choosing the new location, pay attention to the soil conditions, because lavender loves sandy and dry soil. If necessary, you can cut off the rotten roots.

Excessive drought can also lead to brown leaves

Rarer, but also not uncommon, is the drying up of lavender due to lack of water. This is particularly the case in winter when the weather is sunny and frosty at the same time. The winter sun allows any moisture that may be present to evaporate before the plant can absorb it. With little winter rainfall and lots of sun, you should water your lavender moderately if there are signs of dryness. The evergreen plant is dependent on moisture.

Brown spots in Phorma Lavandula

If you first observe brown, then blackish areas on the leaves of your lavender, then it is very likely that it is the so-called lavender death or lavender dying. This is a fungal disease caused by the fungus Phorma Lavandula. The disease can only be treated by removing the affected areas early, otherwise there is no remedy. On the other hand, if the leaves of lavender turn yellow, then it could be leaf spot disease.

tips and tricks

If the lavender only turns brown on the lower parts of the stems, but not in the higher areas - for example on the leaves - then this is neither a disease nor a care error. The lavender lignifies, which is a completely normal process for the plant.
