How to Prevent French Lavender Plant from Rotting

Updated: July 17, 2022

Lavender is a beautiful and fragrant plant that is popular in many gardens. French lavender, also known as Lavandula stoechas, is a particularly lovely variety with its unique flowers and foliage. However, like any plant, French lavender can be susceptible to rotting if not properly cared for. In this article, we will discuss some tips on how to prevent your French lavender plant from rotting.

Tip 1: Ensure Proper Drainage

One of the most important things you can do to prevent your French lavender plant from rotting is to ensure that it has proper drainage. This means that the soil should be well-draining and not too heavy or compacted. If the soil is too heavy or dense, it can hold too much moisture and lead to root rot.

To ensure proper drainage, consider adding perlite or sand to the soil mix when planting your French lavender. You can also add a layer of gravel or rocks at the bottom of the planting hole to help with drainage.

Tip 2: Water Wisely

Watering is another important factor in preventing French lavender from rotting. While it is important to keep the soil moist, overwatering can lead to root rot and other problems. It is best to water your French lavender deeply but infrequently.

During the growing season, water your plant once or twice a week, depending on the weather conditions. Make sure to check the soil moisture level before watering again. If the soil feels dry to the touch about an inch below the surface, it is time to water.

During the winter months, reduce watering frequency as French lavender plants are dormant during this period.

Tip 3: Prune Regularly

Regular pruning can also help prevent French lavender from rotting. Pruning helps improve air circulation around the plant and reduces excess moisture on the leaves and stems.

Trimming your plant after the first flush of flowering can also encourage a second bloom and keep the plant looking neat and tidy.

Tip 4: Control Pests and Diseases

Pests and diseases can also lead to rotting in French lavender plants. Regularly inspect your plant for any signs of infestation or disease. Common pests that attack lavender include aphids, spider mites, and thrips. Diseases such as root rot and powdery mildew can also affect French lavender.

To control pests, you can use insecticidal soap or neem oil. For diseases, removing infected plant parts and applying a fungicide can help.


Can I grow French lavender indoors?

While French lavender can be grown indoors, it is best suited for outdoor growing where it can receive plenty of sunlight and good air circulation.

How often should I fertilize my French lavender plant?

You can fertilize your French lavender once a month during the growing season using a balanced fertilizer mix.

Can French lavender tolerate cold temperatures?

French lavender is not as hardy as other varieties, but it can tolerate some cold temperatures. However, it is best to protect your plant from frost and extreme cold by covering it with a cloth or bringing it indoors during the winter months.

In conclusion, preventing French lavender from rotting requires proper drainage, watering, pruning, and pest/disease control. By following these tips and caring for your plant regularly, you can enjoy the beauty and fragrance of your French lavender for years to come.
