Landscaping under Pest Tree
My pest tree is a very large liquidamber. It is big, healthy and quite beautiful, so I want to keep it. However, it has two major flaws: it produces thousands of hard balls that need to be raked up off the lawn; and the roots are becoming more and more invasive into the lawn. I don't particularly want the lawn (I have other lawn areas to spend my time on). I'm looking for suggestions as to what to do under the tree that will look nice, won't require raking of the balls (I don't mind leaving them as long as they don't start producing offshoots). I have had the tree sprayed once to eliminate the balls the next season and it worked quite well, but I would like to eliminate the expense.
