Okay, I'm an enthusiastic gardener, but not a very good one. I bought a damson tree in April to plant in our new garden. I discovered ground elder in the bed it is going in, so held off planting it in the ground. I put it in a bigger pot meanwhile. It flowered and had lots of lovely leaves but I think I perhaps didn't water enough (before all this hot weather) and it has slowly lost all its leaves bar two which are looking decidedly ill. I've watered regularly since I noticed my probable error and daily in this heat and have put it in the ground now in a different place to give it the best chance but I think I've killed it
Is there anything I can do? Thanks in advance!
