Hi. Im after some help please, looking at my Siberian Elm forest and leaves discoloured yellow with a rusty Edge. The leaves seem dry and brittle. Any idea course, more important how to cure.

Hi @CeramicBonsaiArt  
My guess is that elms like to push hard and those leaves are just spent. They may have got damage somehow and the tree has decided to get rid of them. It looks like you have plenty more good ones and buds to follow.

I’m do glad for this forum and threads like this! My Siberian elm is doing exactly this and for a moment I was worried, but then I remembered seeing something this thread and looked it up again and now I feel a lot calmer.
