I mixed up my Ags, I meants Agapanthus, not Ageratum! How much water do these plants need. They flowered like mad last year but could not but help get loads of water - we are in Cornwall which nearly floated away last year. However, it is now very hot - they ae in pots, and one is about to flower. So let's try again Agapanthus - do they need loads of water?
