> Unlike other members of the genus Acer, it did not put on a blazing autumn display. Its big five-lobed leaves, with their irregular notching, merely turned a crumpled brown. No one minded. As someone who lives next to a neighbor with an enormous old sycamore--I mind! :P The leaves are gigantic and they fall late into Nov, so my entire property gets blanketed with sheets of brown cardstock! Alas it is worth the effo…
I recommend chopping them up with a mower (but don't bag them; leave them in place). The shredded leaves make a really great mulching layer just before winter, when grasses and other plants need that extra insulation, and then they break down and nourish the soil in spring when everything starts actively growing again.
Do this process year after year, and you will have an absolutely gorgeous garden before long. It's a really good reason to plant deciduous trees (especially those that shed a lot of leaves that are too heavy to blow away). But they take such a long time to grow; you are super lucky to have a mature one over your garden already!
