I have quite a few leaf clean ups each season. Some don't really need a actual clean up once the grass stops growing. One particular property DUMPS leaves to the point I can't mulch them after like the third week of doing them. I have to start bagging. Last year I had piles of leaf dust laying everywhere after the third week mulching. It took 3 more clean up visits that took about 3-4hrs each time to finish up for the season at one of them. Over 60 trees on a 1 acre lot! Last fall they had a company come in and remove 8 large trees so this season might not be AS bad though I already started mulching leaves. It's been 9 days and he called today to let me know they need mulched again.
