This raised bed liner is the perfect solution for positioning the bed on a patio or other hard surface. Measuring 97cm wide and 25cm high, it is made from reinforced PE which is heavy duty and rip proof. There are 6 drainage holes in the base, and we recommend that an inch of pea shingle or gravel is placed at the base of the liner before filling with compost. This is to ensure that the compost is free draining and the holes do not get blocked with debris.
