| Well, all trees produce "trash," but they produce different kinds in different ways. Evergreens shed all the time and most deciduous trees just shed once a year all at once. Small leaves might not be the best, as I think they dry up and fall off more readily, whenever there's a dry spell through the drying season. I live next door to an Albizia that sheds its tiny leaflets all summer, right on my back steps, and because they're small they rot down the moment they get wet and turn to slippery mush. Leaves like that would be a headache on a car, more so than bigger leaves that drop all once in fall. Flowering trees produce flower debris as well (the street tree that overhangs our parking spot is a flowering cherry - besides sweeping the pink of the car, we rake in spring). You might also get some help selecting a deep-rooted tree on the tree forum. Or ask at a local nursery. KarinL |
