You really cannot do without one of these. Let’s say, like most gardeners, you’d much rather devote all your time to planting, tending to the plants, buying new plants you may or may not have room for—just kidding, of course there’s room!—and admiring the effect of all you’ve done. However, there’s unfortunately so much more to gardening than plants. Unless standing with a hose for hours is your idea of aerobic exercise, there needs to be an intelligent and easily-managed irrigation system in place. Then, there are all those flagstones, rocks, and timbers that are used to surround the plants (ever try lifting a nice big flagstone?). And don’t forget garden lighting, a very delicate and technically complicated matter.
