- Water a bit at the beginning and then keep from watering as much as possible.
- No need to add fertilizer.

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.

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.

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 wonât grow back…

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.

Cut lavender flowers are an excellent way to perfume clothes and laundry.

How do I know how much to water my plant?
French lavender can take drought but not overwatering. Water only when the dirt around the plant is dry deep down, like a finger’s depth deep. If the ground drains well, water thoroughly. But if the soil retains water well (if you have mulch, for example), then only water a little, like a glassful of water, and wait until dry again.
