Overgrown Lavender - can I salvage?

Personally I think once lavender gets to that stage it spoils the look of it.  I find cuttings take really easily.  I just take heel cuttings off, damp the ends and dip into hormone rooting powder, but I have also just stuck the cuttings in a pot or even straight into the ground and hardly ever lose any.

From 1 plant, I've now got quite a few in my front obrder, which now themselves are looking a bit big and untidy!

This is actually the perfect time to harvest the flowers for drying, and that will sort out the untidy growth problem. But don't prune down to old (hard) woody areas as the plant will not rebloom from those.

I did just that with an old lavendar Zippy and it worked... planted it down deeper, (i actually made some teeny incisions in some of the woody stems to encourage new root production)... it launched new roots and I broke it up into smaller plants from there.
Tried it again with a different one and nada....
Its worth a try- alongside taking some cuttings? Worst case scenario, you'll be digging it up next year to replace- at least burying it deeper will cover the unsightly woody bits in the meantime.?
