I have no idea about gardening. But I'd very much like to save my lovely little bush. Can anyone advise if this is possible. There are webs all over it!

Is it box? Box caterpillar can create that as they chew their way in, you can spray but realistically it is unlikely to recover .

My plant identifier app says it has powdery mildew on it.

Look and see if it's covered in caterpillars, green and black? If it's a box hedge they get infested. You can buy a specific pesticide, amazon have it, you then need to regularly spray (monthly or so) though ours 3 weeks on has no sign of them returning. Ours was far worse (and a full hedge) attacked whilst we were away, it's recovering now, lots of shoots

It's a Buxus (box) plant and that is a box caterpillar attack. If you shake it you'll see loads of tiny droppings fall to the ground. The caterpillars are black and green. Xantari, you can get it from Amazon, is the only product I've found that will treat this. You mix up the powder, spray it on the plant, the caterpillars eat the treated leaves and it kills then. It states that it is safe for other insects as they don't eat box leaves. Normal pesticides wont work.

Oh no I hope I don't lose it. It's one of a pair either side of a bird cage and the area already looks sad given this new grey look!

I will try the xantari stuff really hoping it comes back to life. @NigellaAwesome it does look more like webs, perhaps the picture isn't showing it well enough.

As @Amazongirl9 says it is box caterpillar. There will be sticky webs where the caterpillars hatch and they will eat your box in days. Xen tari is the only thing that works in my experience. In the meantime pick off and squash as many caterpillars as you can find! Then spray with xen tari. I spray about every four weeks from March to October. You'll never get rid of it and have to spray every year. Either that or replace with something similar.
