What resources will my school need to provide to make a Keyhole Garden? Materials for the wall: Maybe stone, brick, timber or other depending on the design and construction of your garden Stone/bricks need to be ‘clean’ of mortar etc. to allow for bricklaying. Broken paving stones are good. Try to use locally found or reclaimed/re-used materials if possible. Materials for the compost basket (depending on the construction): 12-15 sturdy sticks 1.5 m long (ash, hazel or willow are all good) for the uprights of basket. For the ‘body’ of the basket: Chicken wire (approx. 2m x 1m), or a bundle of flexible ‘withies’ (hazel/willow/birch) to weave the basket, or 10 metres of garden string/wireto lash the canes together. 4 x 1 cubic metre (minimum) of mixed soil and compost This is 20x 50kg bags in total, 13x topsoil and 7x compost. Ratio is 2 parts topsoil to 1 part compost. It is advisable that this is delivered close to where the Keyhole Garden will be built. Straw or cardboard For lining the compost basket.
