I bought my first bonsai (a chinese elm) about 7 months ago. I purchased it from a stall in a shopping entre which I realise now was far from ideal, as it has training wire scars on its trunk and was in full leaf in November.
I keep the tree indoors on a west facing window ledge and away from direct sunlight. A couple of months ago it showed signs of black spot which I thought Id dealt with. The tree then started losing its leaves quite rapidly, which I assumed was natural wastage. However, now new growth gets to a certain point then shrivels up but does not drop off the branch. There is still new growth coming through but I know this has the same fate.
Is there any hope?!
