The presence of frogs, salamanders, and even turtles also tells you a lavatory setting is current. If you want to cultivate lavatory vegetation but don’t have a pure melancholy that collects water, create one by sinking a plastic kiddie pool into the bottom. Disguise the sides with rocks, and fill the underside with peat moss and sand. Every species has different requirements, however you’ll usually plant your flowers in early spring, after the last frost. You can even plant many perennials in the fall, earlier than the year’s first frost.
