A genus of about 25 species, this fragrant beauty is an absolute must in any garden. Particularly high in nectar and therefore extremely attractive to bees, the answer from a domestic point of view is to be careful where exactly they are planted. A case of beneficial versus pest, possibly?
Often used in rockeries, as low hedges, in herb gardens, en mass planting or as a border plant… they really are [once again] a must have/ no garden should be without plant.
My main note of advice if choosing to plant lavenders is that they are cut back every season. The problem is that when they aren’t, they do go leggy, the flowers and foliage only appearing on the lasts couple of inches of the stem and the lower [soft] wood becomes almost like a moist cardboard. This leaves them very prone to a soft woody fragile rotting at the base which breaks then quite easily…. which is great for garden centres and people like me…. but not for you
To cut yours back, use a good, clean sharp secateurs. Grab a good tuft of the plant and cut straight across. In a two year old plant for example this will remove the most recent seasons growth.
Of course this all depends on the variety and the varying external conditions. But as a general rule cutting a plant back to half height is no harm. When you’re done give it a good ruffle. Trim up the loose ends and clean around the base of the plant.
However you chose to do it…. even though it might look like a sheep shearer just gave you a bad haircut [at the time] but it is well worth it in the long run
If you are thinking of cropping the flowers for pot pourri, do so before they open fully.
