French lavender appreciates well-draining, light and even poor soils.
It can grow more or less anywhere, but is vulnerable when temperatures drop below 19°F (-7°C) in winter.
- We recommend planting it in fall, but you can plant in spring without any problems.
- Water a bit at the beginning and then keep from watering as much as possible.
- No need to add fertilizer.
- French lavender doesn’t grow well in excessively chalky soil.
Prepare a place that is well endowed with sunlight with well drained soil. If your soil is clay, mix sand into it to make it lighter.
- Refer to our guidelines for planting shrubs.
- To grow a French lavender hedge, plant one stem every 12 to 16 inches (30 to 40 cm).
Planting French lavender in pots
One important tip to grow French lavender in pots: avoid moisture at all costs.
- Double-check that the pot has a hole.
- Add a drainage layer made with small gravel or clay pebbles.
Watering French lavender
Lavender excels at resisting drought. There are only three cases when you must water your flowers:
- just upon planting, once, thoroughly
- during extremely hot heat waves (over 95°F or 35°C)
- if your French lavender is growing in a pot or flowerbed that is covered and never gets any rain.
Expert perfume makers say that the dryer the season, the more fragrant the perfume!
Pruning and caring for French lavender
Pruning French lavender is possible, but must be exclusively performed on growth that still bears leaves. If you prune dry wood, they won’t grow back…
- At the end of winter, prune as you wish, but follow the rounded shape of the plant.
Avoid cutting off old growth, because those branches rarely send out new shoots.
Favor pruning only on young, tender shoots rather than old, hard wood.
- If your climate zone has mild winters, you can also trim your lavender bush in fall.
- After the blooming, snip off floral scapes to avoid needlessly draining plant nutrients.
Cut lavender flowers are an excellent way to perfume clothes and laundry.
French lavender in winter
