WATER RIGHT HOSES: Many years ago I gave away all my too-heavy garden hoses in favor of lightweight, drinking-water-safe and US-made ones by Water Right Inc. The 400, 500 and 600 series each have slightly different diameter; most of mine are 500 series. My favorite color is the olive. The most asked-about tool here in my garden during tours.
STAINLESS HORI-HORI KNIFE: Part trowel, divider, weeder and just general all-round workhorse, and even better than my original Japanese weeding knife, which wasn't stainless. A brilliant upgrade that is particularly brilliant between pavers and other cracks and crevices.
STAINLESS EDGER: If my half-moon step-on edging tool ever dies (a model that's no longer made), this stainless Sneeboer is the near-identical replacement. Good edging makes a world of difference, and (like mowing) you get instant gratification: things look better right away!
