Planted this two years ago and it did well last year. This year it put up a fair few new flower heads but now seems to have dried up and withered away with just a few clusters of green leaves remaining.
I was at a nursery earlier and their limited amounts of French lavender were also looking a bit ropey. I have several other varieties of English and white javelin lavender in the garden and they are all thriving.
Any ideas? Is it worth trying to save or should I just dig it up and try again?
