Pruning

Pruning can take place at any time of the year but is best after flowering
or in Autumn, well before any frosts are due, as they will burn any new
growth. Lavender hedges need pruning twice per year.
A third of the bush can be safely removed. Lavender plants that are
not well pruned annually, are prone to become woody in the centre
and will eventually have to be replaced. Even new lavender plants
need to be pruned slightly as this will help make the plants
bushier and more robust.
