No flowers on bergenia
I have bergenia in several places round my garden but they have flowered less and less since we moved here nearly 4 years ago, so far no flowers this year, whereas I noticed lots of flowers on those at the hospital we have just attended. They are not gappy and have lots of healthy leaves. Should I be dividing them and replanting the youngest bits? Is it too late to do it now? If not, do I dig in a lot of compost, adding some fertiliser (e.g. blood, fish and bone), before replanting?
