Lush, dark green foliage and large, colorful flowers start with an exceptional fertilizer. Nourish your flowering trees and shrubs from the surface above and below ground with Miracle-Gro Shake N’ Feed Flowering Tree & Shrub Fertilizer. It’s specially formulated with essential micronutrients and organic ingredients, like seaweed, earthworm castings, feather meal, and bone meal. This is important because the microbes in the soil break down THESE ingredients into the essential nutrients that plants need for good health and strong roots. This also increases the efficiency of the water. Simply shake on flowering trees, shrubs, and other acid-loving plants to feed them for up to 3 months.
