Answer:
Hi Dominique, This poor plant is winding down to die, but there is a chance of saving it…maybe 50%. For the time being, water the plant once a week for 5 minutes at least. Water shortage is almost certainly the main problem. In August carefully dig it up, trying to gently get all of its roots. I suggest that you pot it up into a pot large enough to fit all of its roots in, using Premium potting mix. Give it some Seasol to try to get the damaged roots to grow. Put the plant & pot in part shade until mid September, when it should go into full sun. Water twice a week from when you potted it up. Good luck, you will need it. Don
