Guide to Growing French Lavender Plant in a Pot

French lavender (Lavandula stoechas) is a beautiful and fragrant plant that is commonly grown in gardens, but it can also be grown in pots. In this guide, we will cover everything you need to know about growing French lavender in a pot, from selecting the right pot to harvesting the blooms.

Choosing the Right Pot

The first step to growing French lavender in a pot is choosing the right container. The pot should be at least 12 inches deep and 12 inches wide to provide enough room for the roots to grow. Make sure the pot has drainage holes at the bottom to prevent water from accumulating and causing root rot.

Soil and Fertilizer

French lavender prefers well-draining soil that is slightly alkaline with a pH between 6.5 and 7.5. Use a high-quality potting soil mixed with perlite or sand to improve drainage. Fertilize every four to six weeks during the growing season with a balanced, water-soluble fertilizer.

Watering

Water your French lavender plant deeply once a week during the growing season, and reduce watering during winter when the plant is dormant. Avoid watering the leaves to prevent fungal diseases, and let the soil dry out between waterings.

Sunlight

French lavender needs full sun to thrive, so place your potted plant in a sunny spot that receives at least six hours of direct sunlight per day. If you are growing your plant indoors, place it near a south-facing window or under grow lights.

Pruning

Prune your French lavender plant in early spring before new growth appears. Cut back one-third of the previous year’s growth, removing any dead or damaged branches. Pinch off spent blooms throughout the growing season to encourage bushier growth and more flowers.

Harvesting

Harvest French lavender blooms in early summer when the flowers are fully open but before they start to fade. Cut the stems just above the leaves, leaving some foliage on the plant to encourage regrowth. Hang the stems upside down in a well-ventilated area to dry, then use the dried flowers for crafts, cooking, or aromatherapy.

Common Problems

French lavender is generally a hardy plant, but it can be affected by pests and diseases. Here are some common problems and how to address them:

• Root rot: caused by overwatering or poor drainage, root rot can be prevented by allowing the soil to dry out between waterings and choosing a well-draining potting mix.
• Powdery mildew: a fungal disease that appears as white powder on the leaves, powdery mildew can be treated with a fungicide spray or by removing affected leaves and improving air circulation.
• Spider mites: tiny pests that suck the sap from leaves, spider mites can be controlled with insecticidal soap or neem oil spray.

FAQ

Can French lavender grow in cold climates?

French lavender is native to Mediterranean regions and prefers warm temperatures. It can be grown in colder climates, but it may not survive harsh winters outdoors. Consider growing your plant indoors or moving it to a protected spot during winter.

How often should I fertilize my French lavender plant?

Fertilize every four to six weeks during the growing season with a balanced, water-soluble fertilizer.

Can I grow French lavender from seed?

Yes, French lavender can be grown from seed. Start seeds indoors in late winter and transplant seedlings into pots when they are several inches tall.

How long do French lavender plants live?

French lavender plants can live for several years if given proper care. They may become woody or leggy over time, but can be rejuvenated by pruning back one-third of the previous year’s growth in early spring.

In conclusion, growing French lavender in a pot can be a rewarding and enjoyable experience. With the right pot, soil, water, and sunlight, you can enjoy the beauty and fragrance of this lovely plant all year round.
