Anchored by a galvanized steel frame this 4 x 2 x 3 ft raised garden bed includes a built-in greenhouse cover that extends the growing season for tender seedlings. The open-bottom planter lets roots reach deep into native soil while the Pe cover traps warmth and shields plants from frost. Roll-up access lets you tend the bed without removing the cover. Reinforced side walls resist soil pressure and the rust-resistant coating extends outdoor service across all four seasons.
