Our two litre Cardboard Carton Tree Guard is a cost effective way of protecting faster growing young trees. Ideal for large revegetation projects, the 2L cartons provide an ideal shelter for tube stock during the first years of growth. Over time the sun and rain will degrade the cartons which will break down into the soil. When using these cartons only two bamboo canes are required per guard. We stock 2 litre cartons in boxes of 250 pieces.
