With an analysis of 12-0-0, Whitney Farms' porcine blood meal is a fantastic natural source of pure nitrogen. Nitrogen is an essential ingredient for shoot and flower growth. Use it on a wide variety of plants, including flowers, vegetables, bulbs, tree and shrubs. Feed every 2 months during the growing season. Simply apply it directly from the bag to the soil around your plants. And because it's protein based, there's no manure smell - so there's no manure odor.
