Propagation of Sycamore tree by seed
I have some sycamore seeds from my boss's back yard that I'm guessing are from this year? We are at the border of zone 5/6 in Illinois. How does one go about growing these seeds? Do you let them winter outside and plant the next spring? How deep, etc. would you plant? I've read that sycamore seeds are easy to grow but can't find details on how to grow them.
