Not only do the butterflies love it but you can use the flower heads to make tea before bedtime to help you snooze and you can dry the flower heads and put them in tiny cushions like Grandma used to make - then put them in your drawers to make your clothes smell nice - or on your pillow before bedtime to again help you sleep.
Foolishly I've ignored my English Lavender for quite some time without pruning it and so it has become woody and unattractive.
Woody and Unattractive
I am disgusted with myself.
The problem is, I can't really find any one argument to say when is best to prune or how best to prune.
Fortunately I've found a lady on YouTube who seems to know what she's talking about (I think it might be her American accent that inspires confidence in her ability - - I'm going with her:) ).
I read somewhere that all silvery shrubs - such as Curry plant and Lavender - should be pruned around May time. So now is probably a good time to prune - and then again you should dead-head in late summer after flowering.
As for my Lavender, I think it's time to say goodbye. I've neglected it too much, it's beyond help.
Here's a love song to say goodbye.
