Miracle-Gro Shake 'N Feed Flowering Trees and Shrubs Plant Food is designed to help flowering trees and shrubs thrive with enhanced green foliage and vibrant blooms. The formulation includes natural ingredients like kelp, earthworm castings, bone meal, and feather meal, which feed plants for up to 3 months. This fertilizer is suitable for in-ground gardens and container plants, specifically targeting acid-loving species.

It’s easy to apply by spreading it on the soil around the plant's base, avoiding direct contact with the trunk or leaves, and watering afterward to initiate feeding. Reapplication every 3 months is recommended for optimal results. Weighing 8 pounds, it is relatively easy to handle and comes in a practical size for multiple applications.

One of the main strengths of this fertilizer is its organic content, which can be beneficial for those looking to maintain a more natural garden. However, it may not be suitable for non-acid-loving plants, and users need to ensure it is compatible with their specific soil pH. Additionally, while it feeds for an extended period, regular reapplication is necessary to maintain plant health. This product is ideal for gardeners seeking a natural, long-lasting fertilizer for their acid-loving flowering trees and shrubs.

This 10-10-10 slow-release granular fertilizer offers a balanced mix of nitrogen, phosphorus, and potassium, each at 10%, making it a versatile choice for a range of plants, including arborvitae. Its slow-release formula feeds plants steadily for up to eight weeks, reducing how often you need to apply it, which is great for busy gardeners. The mix supports strong root development, healthy green growth, and overall plant resilience—important for evergreens like arborvitae that need steady nutrition to stay vibrant year-round.

The fertilizer granules spread easily and absorb well into soil, ensuring even feeding. It also includes a quick-release nitrogen boost for faster initial growth, which can help young or stressed plants. However, the product is synthetic rather than organic, so if you prefer all-natural fertilizers, this might not be ideal.

Designed as an all-purpose fertilizer for many plant types, this product works well for gardeners seeking a simple, effective option for shrubs, trees, and flowers without buying multiple products. It is well-rated for its ease of use and reliable feeding. If you want a straightforward, balanced fertilizer to keep your arborvitae healthy and growing steadily, this product is a solid choice, especially if you prefer to reduce frequent applications and do not mind synthetic ingredients.

It is also easy to apply, with fine granules that spread evenly across the soil for maximum absorption, which is beneficial for even coverage in larger garden areas.

While it is marketed as suitable for a variety of plants, including evergreens like arborvitae, understanding your soil’s pH is crucial as it does not detail specific pH compatibility. This product is best suited for users who are looking for a straightforward, all-purpose fertilizer and are comfortable with synthetic options. Those pursuing organic gardening might need to consider supplementary or alternative fertilizers.
