A CLEARING IN THE WILDWOOD : Page 24

Vines growing wild on trees will strangle or smother them eventually. Cut them at their roots and they will fall away in time. Not harmful are morning glory, an annual, and trumpet creeper, which climbs free, without throttling, and whose deep-necked blooms the hummingbirds love. If you value the trees you find them on, show no mercy to wild grape, honeysuckle, woodbine, poison ivy, or wisteria (which you can cut back partially and then train to a support all its own). The evergreen ivies—English, American, Boston—are decorative on tree trunks but should not be allowed to grow much above the first main crotch.
