Any clues of what is eating my Canna Lillie's
Regally treat them with a bug treatment, but the instructions say only apply 2 or 3 times in 6 mths.

    Looks like slug damage, the holes on the top left leaf give it away. When the canna sends a new leaf up in a spiral slugs sometimes eat through it causing the multiple holes in a row.

    Thanks,

    But cannot see any trails on the grit or pot etc.

    There’s no point in treating slugs with bug killer.

    They don't always leave trails TW.  If they come out when it is damp, they don't need to produce the slime.  Try a beer trap which will attract any slugs and snails in the immediate area.

    Lidl’s cheap lager goes down well here 😀. (For the slugs I mean)

    Mine's a Theakstons please, very kind of you!  :D
    Even yeast, sugar and water mixed together has the same effect (on the slugs, but not me!), if no amber nectar is available.

    Thanks all,
    Going to try a deterrent method first, where as seen on GW boiling some Garlic cloves and mixing some of the boiled garlic water and water in a spray. Spraying once or more a week.
