Miracle-Gro Shake 'n Feed All Purpose Plant Food is a slow-release granular fertilizer that feeds plants for up to 3 months with just one application. This 8 lb jug contains a unique formula with a 12-4-8 NPK ratio that nourishes plants both above and below the soil.

The formula contains natural ingredients including kelp, earthworm castings, feather meal, and bone meal that feed beneficial microbes in the soil. These microbes break down the natural ingredients into nutrients that support root strength and development, which increases water efficiency. The result is stronger, more vibrant, and more productive plants compared to unfed plants.

This all-purpose plant food is versatile and can be used in ground gardens, raised beds, and containers both indoors and outdoors. It works with all types of plants including vegetables, flowers, trees, shrubs, and houseplants. Application is simple: shake the granules evenly onto the soil, work them into the top 1-3 inches, and water thoroughly. Use 1/2 to 3/4 cup per 10 square feet of garden space, or follow container-specific measurements ranging from 1 1/4 teaspoon for a 6-inch pot to 5 tablespoons for a 14-inch pot.

The fertilizer provides essential nutrients plus additional calcium, magnesium, sulfur, copper, iron, manganese, and zinc. It is guaranteed not to burn plants when used as directed. Reapply every 3 months during the growing season for continuous feeding and optimal results.
