can you plant the dutch iris seeds collected from the seed pods? »
Most likely to be Acer Tar Spot, though a photograph would confirm that - or not. If it is, leaf drop can occur early -no control available, but none necessary either, other than making sure you collect up all fallen leaves as they come down and don't let them lay on the ground over winter. The pest which causes this overwinters on the dead leaves, but this problem doesn't usually kill the plant.
