This 2 year old plant’s leaves have started to dry up around the edges - can anyone advise what may be the cause (I water it regularly) & what can I do to help it recover?
Do as Madpenguin says. Try gently lifting the plant up - you will probably find it has no roots and comes away easily. Heucheras can look like this for a long time after the grubs have chewed the roots.
They regularly get fried round the edges, even if no weevils are present. Just remove those leaves - it'll constantly produce new ones. There's a lot of competition in that pot for water though Hebe, Ivy and primroses.
They also push themselves out of the ground - which is what yours is doing. If you remove it and pot it up itself, it'll probably do better. Shady site as well to prevent it drying out too much.
It's a place where beautiful isn't enough of a word....

Last year I had a beautiful Heuchera 'Solar Eclipse'.Towards the end of the summer it seemed to suddenly droop and I was able to lift the whole plant out of the pot and there was not a single root! How it managed to put on such a display I really don't know.
