I saw an old thread from 2010 regarding bows & arrows from sycamore shoots. Sure wish I 'd had the interest in DIY when I was a kid. Several sycamores were in the school yard across from our
house & had lots of shoots every year. Too bad we don't always know what we have til it's gone.
Someone there also posted about the pesky leaves. I know about that too. I spent 2-3 hours a day raking & burning sycamore leaves. Good thing though, is that when dry they burned very well. I would rake up a 10-15 foot wide pile, 2-3 feet high & light them up. Flames 30 feet high for a few seconds. Within 5 minutes, fine ash that would barely fill a small bucket. Then do it again. Small oak leaves were the worst. They did not burn, no matter how dry. They smouldered all day.
