I would remove the crispy leaves and give it a real good soaking to encourage new growth.

I agree a really good soaking for new growth from the base. If you are still forecast for uninterrupted sun I'd leave the crispy leaves as protection for any new/green growth.

No consolation but mine looks the same!

Its still got plenty of green. They do like moisture so like a lot of other things it will have struggled lately. It will be fine - just don't let it get too dry for a while.

Thank you all yes it hasn’t enough water I know so will pull the hose around this evening it’s quite a distance around to my front garden and have just no felt up to doing it the heat 😕 but a bit cooler today .
