Self watering is the reason this raised garden bed can go days without attention. Water sucking columns draw moisture up from a reservoir into the soil as the plants use it, so the routine becomes topping up a tank instead of watering daily, and a water level observer on the side shows how much is left, which is what stops the guesswork that leads to over-watering. A water separation net with vents sits between reservoir and soil so roots stay aerated rather than standing in water, and two side drainage holes give heavy rain somewhere to go. The rectangular planting box takes 28 by 13 by 8 in of soil at 9.2 gal and 66 lbs, sized for flowers, vegetables, herbs and fruits. Rising from it, a U-shape climbing trellis strung with high-strength nylon net turns the vertical space into growing area for climbers, and the whole unit reaches 74.5 in tall on a 30 by 14.5 in base. The 15.5-in legs detach, which changes what the piece is: legs on, the soil surface sits at 26 in for standing-height work; legs off, the same box drops to ground level as a flower box. Frame pipes are PE coated rather than bare metal, giving a cooler surface that avoids harming the plants touching them, and the box is odorless PP with smooth curved corners in place of sharp edges. Horticulture buckles and metal secure clips join it together, and at 9 lbs the empty frame carries outside easily.
