butterfly lavendar

Was this due to under-watering? I would water it, cut back this year's growth and keep my fingers crossed for signs of new growth. You might be able to take cuttings if this happens but I don't think that the bushes will revive fully.

Thanks Spritzhenry I will try it and see what happens.
Erm yes I think it may be due to lack of watering....I may try to make one of those contraptions out of a bottle of water...which slowly waters your plants for you.....
Can I ask another question ....
what would happen if I transferred them to the garden?
Oh and also whats the best way to maintain them? ...If I but new ones?
Thanks
:-)
