Poly Bag were traditionally used under glass and were introduce as an alternative to planting directly into greenhouse soil. Not having permanent borders meant the space could be used more efficiently throughout the year and plants would not become infected by soil-borne diseases. Today, they’re still ideal for growing plants in the greenhouse, but are also perfect in a sunny spot outdoors.
