Cabbage collars protect cabbages and brassicas from cabbage root fly – a simple and efficient way to protect your spring, summer and autumn greens from an attack.
• Simple, efficient and non- chemical
• Prevents the adult fly from laying eggs near base of the plant
Cabbage Collars are easy-to-use. Once planting has taken place, slide the collar around the stem. As the stem thickens, the Cabbage Collar will open to prevent restricted growth.
Suitable for environmentally-conscious gardeners, each pack contains around 30 collars.
