Today whilst at Kew Gardens I saw some cotton lavenders in a border that was pruned within an inch of their lives and to my great surprise, they were sprouting from old wood. I always thought they didn't do that. I have one that is in desperate need of hard pruning but I haven't since you shouldn't. Has anyone tried this on them with success?
I cut mine down to about 3" every winter and they re grow every year to a height that doesn't swamp the border nor look leggy.
Becareful with the Lavender, that can't be cut back to old wood. That won't regrow.
Lavender and cotton lavender are not the same plant and can't be treated in the same way. Lavender is lavandula, whilst cotton lavender is santolina. If you cut into the old wood on lavandula it will not regenerate and die.
Thanks for the advice. I know this is a cotton lavender as I still have the lable. I will give it a trim tomorrow unless the heavens open again.
