Good day everyone, I made a few brush piles out of oak limbs last summer and wanted to ask if anyone had any idea how long the leaves would stay on. Reason I ask is I cut some low hanging limbs some Bradford Pear trees in the yard. I am about 8 weeks into a knee replacement so it may be 3 or 4 more weeks before I can crawl in the boat. The leaves on the limbs will be drying up and falling off and I was wondering if would still be worth it to sink the limbs without any leaves. Thanks
