Ive had my chinese elm for about 2 years and it has dropped all of its leaves once and has the odd yellow leaf that drops but alsways looked fab.
Within the last 2 days patches of what looks like dead leaf have appeared on leaves on nearly every branch ive never had this problem before and have had bonsais for about 15 years.
Any ideas. The only thing i can think of i sprayed a household flea spray in that room a few days ago with all windows and doors open round the skirting could this be it?
If anyone could help Id be very grateful
