How to use

Before use, shake the growbag until the compost has loosened to provide a greater depth for planting. Cut along the dotted lines on top of the pack to reveal 3 planting holes. Add about 7 litres (1.5 gallons) of water. Place in planting holes and firm compost around each plant.


Using canes for support

Position canes next to each plant being careful not to damage the plant roots. Train main stem up the cane, securing with garden string. When growing tomato plants, remove all side shoots from between the leaf and the main stem. When growing tomatoes aid pollination by carefully shaking or spraying the plants on a regular basis. 


Keep moist, never allow to dry out. If necessary, cut drainage slits in the side of the bag to prevent it from becoming water logged in wet weather. Water frequently in hot weather. When first truss has set, feed with Gro-Sure Tomato Food.
