I agree with Verdun, he said
"..... I would dig it up and loosen those roots. Unwind them and spread them out. Before replanting dig in plenty of compost, dried manure, etc and water well. Can you give it a slightly less sunny spot too?...."
That's exactly what I would do, and now is the perfect time to do it. I would only add .... before digging it up give it a through soaking.
