we have an acer, small tree, green leaves, planted in the garden where it's been for 4 years. I've been watering it regularly along with all the other plants and given it 2 weekly plant food. Both it and the little rose right next to it have suddenly wilted in the last few days - leaves drooping and crinkled up. The tree stem still looks healthy but the leaves look like the acer is dying.
I'm baffled. Any ideas?
PS I've just seen the other, main gardening thread! sorry
