A small bag of "earth" Approximately a rounded dessert spoon of a dark brown sawdust like material which makes wonderful earth to finish off the tops of pots or flowerbeds.
It goes a long way and one bag will be sufficient for many pots. Once your flowers are planted in their pot (using an air drying clay or a plasticine type material). Simply brush the surface with slightly diluted Tacky glue and sprinkle the earth on the surface in a generous layer, pat down if you wish. Once the glue is dry tip off the excess earth and return to the bag.
