The following years,
in March or April clip off a few centimeters from the shoots from the previous year. Never prune further back than the current year's growth. Lavender mustn't grow too quickly, otherwise it will thin out at the base. After flowering, in the end of summer, prune your lavender plants. Take this opportunity to gather the very fragrant flowers. Dry them and use them to scent your linen cupboards!
Be careful not to prune lavender into « dry » wood in the center of the bush because the lavender won't grow back well (the formation of new shoots on old wood is uncertain).

It is easier and quicker to start over again with a new plant.
