How it was done; Sweet peas/beans supports were bits of wire soldered up and painted. Onions (or leeks) are dyed hemp stuck into holes (as used for the reeds on the nearby drain). Strawberries (or such) simply Heiki foliage. Woodland Scenics would be just as good. Dab of paint here and there. Same used for the beans/peas. Slug eaten cabbages are little squares of printer paper (1x1cm) soaked in greeny brown acrylic (cheap set from Tesco) squeezed and rolled into balls whilst wet. Mucky job.
