Question
I live in St. John's Newfoundland. I have five large maples that this year have produced an exceptionally large number of new seedlings that seem to have taken over my lawn. What can I do to stop their growth so that my grass can grow?

Answer
Are you looking to stop the growth of the seedlings or the large trees?  The seedlings will die after a few mowings, the trees are a tougher to handle.  About the only way to control the trees other than a severe pruning are removal.  

Please let me know if you have any further questions.

Thanks,
