Hi I have 3 of these and mine have made decent growth of about 6 inches, I'm not too far away from where you.live so I would assume yours should have been well on the way too, are they in full/mostly sun? :)

Daylily - they were planted in a sunny border but thinking back I fear the quality of plants wasn't great. I think they have just perished. My boarders are pretty packed so I might have overlooked them and forgot to water?

Hi, Its happened to me too I have bought plants before and they do not come back then I have stuff I'm not expecting to see again but they survive so its a difficult one isn't it, could slugs/snails have had them., mind you I didn't notice them attacking mine, as you say they may have just perished, I bought two heucheras last year from the garden show the ones fine but the other has just disappeared in the pot, just a few dead sticks :(

I am hopeless at remembering to care for plug size plants as have been ill a lot last year. My solution was to progressively pot on and on into 2-3 litre pots. You cant miss them when you plant them then, particularly if they are in strong growth when you plant them out, and not too rootbound.
