The 30cm deep V-shaped trough allows efficient use of soil. It lets you grow deep-rooted plants such as carrots in the centre while growing herbs & shallow-rooted vegetables closer to the sides. The synthetic felt trough ensures good drainage & soil aeration, & has hook &-loop fastener strips around its edge for a secure attachment to the frame. A tightly woven inner layer keeps soil contained. The planter stands about 80cm tall, a height that lets you work comfortably without stooping. The frame is sturdy steel with a powder-coat finish & stainless-steel hardware for rust resistance.
