A fantastic addition to our school garden is our new Keyhole Garden! A traditional keyhole garden is a raised circular garden bed with a wedge-shaped cutout along one side that gives easy-access to a compost area in the middle and growing areas on all sides. This central composting section works as a self-fertilising element for the plants, keeping the soil naturally replenished.
A composting basket at the centre of the keyhole raised bed is used for watering the vegetables, keeping the soil wet from deep within the bed. This method of watering directly through the middle gives nutrients to the plants on a regular basis. Organic food leftovers and paper goods that might otherwise end up in the general rubbish are recycled, helping to reduce waste too. The concept (having originated in Africa) was originally created for hot, dry areas – this means they retain water better so don’t need to be watered as frequently as other raised bed types.
Our keyhole garden is a creative adaptation and along with other initiatives in our school will help in some little bit to counteract climate change and improve environmental sustainability.
A big thank you to Michael and Eleanor Allen for the donation of the building stone (from their farm) which was used to create the Keyhole Garden!
