This is my first thread so I hope someone can solve my dahlia mystery! I live in Switzerland and a few weeks ago I planted out the dahlias I had grown from tubers (pink Giraffe) along with a few others. They were a decent size and I surrounded them with slug pellets just to be safe and today I went for a walk around in the garden and 2 of dahlias had disappeared...only a neat hole was left and no soil had been disturbed?! What could this be? I'm so annoyed I was so happy to find pink giraffes here now they've disappeared into thin air!! There aren't any moles around and we live in the middle if nowhere on a farm? The other dahlias in the same bed are fine (so far) and the ones eaten arent next to each other but in the same bed. Please advise before I lose anymore!
