A quick acting nitrogen fertiliser to encourage leafy growth. Vitax Sulphate of Ammonia is particularly beneficial in leafy vegetable and salad crops such as brassicas, lettuce, spinach, rhubarb and leek. An early feed also gives flowering plants, shrubs and fruit an extra boost and will quickly green-up a tired lawn. It can be applied at the recommended rates throughout the growing season. Simply spread evenly and hoe or fork into the top surface of the soil. Water-in during dry conditions. Always read the label on your purchased product before use.
