What makes you think it's not slugs or snails ?

Its usually slugsand snails and they are very good at not being seen. If you don't want to use pellets there's now a liquid that you water on the leaves. Worth a try anyway as the tumblebug doesn't work.

Try SLUGCLEAR.water on leaves and on the roots.

What made me think that is wasn't slugs or snails because the pots that the hostas are in are very shiney & has lavers of gravel covering the top of the compost also I have them standing on a bed of gravel, which I thought would have deterred the little devils from coming anywhere near but not so. Also lots of the leaves have small holes in them & that made me think of insects etc . Today on close examination I have spotted some snails & I must say very well hidden. Thanks

Great, I will definitely try Slugclear Thanks

Hi, it doesn't sound as though your hosta's are being eaten very badly, it sounds as though they are being eaten very well :-), Derek.

Well slugs and snails are the experts after all Derek...

Hi Sue, indeed they are, :-), Derek.
