Hi guys. It's just past mid summer here in Oz, and I have a corky bark elm which started to lose vigor a month or so ago. Then started to develop little black spots on leaves. The leaves started yellowing soon after, and then dropping off. Still has about 2/3 canopy, but looks Unhealthy. Most new buds turn black from the tip, and then get brittle and drop off. I tried treating with insecticide (on advice of another bonsai enthusiast), but to no avail. Now my chinese elm has just started to show similar symptoms. Has had poor vigor for 3 weeks or so, and a couple of telltale black spots have just started to appear. Some leaves have started to yellow.

Another bonsai enthusiast suggested it may be a fungus, and I should treat with a fungicide. My questions to you all is:
*any of you guys had this stuff?
*can I use any fungicide to treat a bonsai? should I be looking for anything in particular?

Thanks for your advice with this - really want to get to the bottom of this!

yes. use a fungicide, and remove the leaves that are bad. try not to get water on the leaves until it clears up. (hopefully it will)

M. Just wondering how your elms came out? If so, what did you use? Vic
