Water Hawthorn dead?

I really dont think its worth doing anything until growth restarts, once it starts growing you can move it around then, but until that happens I don't think anything you do will make any difference.

 

Noted! Thanks @pete

 

I would do that @latimer - a brick or two would do the job. It's perfectly normal for them to disappear over summer when it's hotter, and they'll grow away again when it's cooler. Late spring and early autumn is when they're at their best. It'll settle and flower next year.

That's precisely why I have the white one @Goldenlily26 . Pale blue is a colour I can't abide
