These trees are causing so much work on our side as all the spring seeds and broken twigs etc. are covering our deck and garden. I have to fill at least 2-3 brown lawn bags a week. Now we have these small paper like flat white discs everywhere (again I can not keep up with them) and now there is little green spores ? growing everywhere (even between the boards of out deck. I am exhausted and the neighbour will not take them down. What can I do about these things that are growing everywhere (short of digging up my whole garden.
Thank you for contacting Toronto Master Gardeners about your problem. You may lessen the amount of debris from the elm twigs, seeds, and other falling matter by having the branches of elms that overhang your fence trimmed. We recommend a professional arborist for this task, as you need to be careful not to cause any damage to the health of the trees.
You may contact Landscape Ontario for a member who is an expert on this.
