Our Wormeries not operational

We have been unable to make  arrangements for the provision of friut and other "lunchbox"  food waste for the wormeries at the Botanic Garden so the wormeries are not fully operational at present. The worm compost can be seen in the lower layers of the stacking wormeries but  there are no worms in the top trays where they woud normally be feasting on the food waste.
