Agapanthus - one flowers, one doesn't!
I have two identical pots of a pale agapanthus (possibly Blue Ice), potted up at least 10 years ago. They sit either side of a S/SE facing door in Bath. They have both flowered in the past, though not brilliantly but last year and this, one pot has 3 blooms, the other has none. The foliage looks fine. Where am I going wrong? If they need to be more pot-bound how am I going to succeed with Ag. Navy Blue which I'd planned to put in a border?! Any advice gratefully received...
