Cabbage Brassica Collars With Copper

Cabbage collars to deter cabbage root fly, repel slugs & snails, control weeds around the plant and conserve moisture.
Collars are discs of black heavy duty fabric impregnated with copper, 12.5 cm (5") in diameter. The collar is cut to the centre, giving a tight fit around the plant but allowing the stem to grow without restriction.
