Last year I planted two different varieties of Campanula -- at least three of each variety. One was Carpatica and the other one was Persicifolia. Both varieties flowered really well and because they are perennial, I thought they'd die back and grow again this year.
Unfortunately, only two plants out of the six that were planted have started to show signs of new growth. I can't find any sign of any of the others (it's not difficult as I only have a small border).
Where do these plants disappear to ???
I know we had a very wet, mild winter and the most likely culprit is slugs/snails but surely even they would find it hard to devour at least four fairly large plants ????
all advice welcome, thanks
