Q.My Alliums That I Planted Last Year Haven’t Appeared At All This Year (no Foliage Even), What Do You Think Has Gone Wrong?
I think I may have cut the flowering stem back to the base too soon. They’re planted amongst lavender and campanula – is this ok? Many thanks.

It is OK to deadhead the blooms, but leave the foliage. When the foliage yellows and dies down you can cut back the whole plant. It may not have been anything you did that caused them to disappear. It could have been weather related or the bulb itself. You just never know for sure. I have lost lots of plants after one year.
