Gardeners Question Time

[ed_pete]

One of my Heuchera's is having its leaves munched by something. Unlikely to be slugs (slug pellets abound). Can't see any caterpillers. Possibly the dreaded vine weevil ? If anyone knows the most likely cause and the best solution it'd be much appreciated.

Good thread.

Your first pic - what's that plant in the background with the biggish tear drop shaped green leaves? Reason I ask is that I have exactly same problem but with that one. It's potted and I put copper strips around the pot rim, organic slug pellets in the soli, no sign of snails or caterpillars. And its getting munched every night.

To stop slugs crawling up pots the copper strips need to be a couple of inches or more wide as slugs can curve over them.

Rough sandpaper is also pretty good to wrap around. They hate that.

That's a Hosta. Absolutely loved by slugs and snails. I've tried all the tricks for these: copper rings, grit, coffee grounds, egg shells, beer traps. Slug pellets are still the best though, IMO.

Also, copper pan scourers - un scrunched and put around base of plants.
