Nature buzzes along, fed by the warmth and rain, and it's time to mow the lawn again. Before you haul out the weed-whacker, consider this: various life stages of spiders, ladybugs, ground (black) beetles and lacewings, with big appetites for "bad" bugs like aphids and slug eggs, live in and around the tall grass. Try to go easy as you trim, and boost your garden karma. Treat yourself to a new, high-quality hand-edger, don those knee pads, and get a "bug's eye view" of the garden. At the very least, leave a few grassy areas long, and let the beneficial insects do their work.
