That is very typical of snail damage. Lack of flowers is more likely to be hunger than the leaf problem. Feed your plant with Tomato fertiliser at half strength every 10 days or so, until after the normal flowering time, then switch to Maxicrop, half strength until the plant goes dormant.

Hi Kate - glad you can now post. Those snails are a real pest. Try Sluggo of something similar. Those blood pellets really work for me - not a snail in sight.

Thanks Owdboggy, I thought it may be snails or slugs if it wasn’t the beetle. I’ll definitely look at the tomato feed, I can pick some up while shopping.
Thanks Paul, yes, I was quite pleased I managed to post a question straightaway! I’ll have a look at what you suggested, it may be called something else here? I will have to try it, my hosta right next to it is now suffering the same fate! Where are the hedgehogs when you need them? Haven’t seen one for absolutely ages!

That's good. I mentioned it to Dave. He's the administrator. Maybe he fixed it on the back end. He's the guy you'd want to contact with any queries regarding this site. Here's the link for Dave.

Thanks for this, Paul! That’s kind of you. Much appreciated, I’ll take note of this.

if you decide to use slug pellets then avoid the ones with metaldehyde, and methiocarb in them. They cause damage to other wildlife.
Sluggo is available here and uses iron (III) phosphate that makes the slugs stop feeding and they burrow in to the soil and die.

If you don't have slugs then hedgehogs are less likely to visit your garden. You could do an evening torchlight search and pick slugs up.

Thanks Eileen. I’m thinking maybe lifting the lily and the hosta and potting them up..
