What could be eating my plants

I second the sacrificial plant idea. Look up Nasturtium.

French Marigolds is another option, but this one is for repelling bugs. Garlic too. Garlic would put your carbon filter to the test, as if canna is not stinky enough already LOL!


Personally I would not drench the canna with neem, or any oils for that matter, may be a dab of it here and there on the leaves, well away from the buds, but that is just me.

I used the peppermint oil and water spray on the leaves only to be clear, I would also never spray anything on the buds, hell I don't even like them getting wet lol.

Had a similar problem, except I was raisinig seedlings and kept finding them chewed off at the base. Finally found a cricket that had gotten into the tent. Killed the cricket, no more problems! Your plants are established, unless it gets a lot worse I wouldn't worry too much.
