10 Best Fertilizer For Arborvitae 2025 in the United States

The 10-10-10 Plant Fertilizer Slow Release is a versatile option for those looking to support a wide variety of plants, including arborvitae. With its balanced NPK ratio of 10% Nitrogen, 10% Phosphorus, and 10% Potassium, this granular fertilizer is designed to provide a well-rounded nutrient supply that promotes strong roots, lush growth, and vibrant blooms. It's suitable for outdoor and indoor use, making it practical for both garden enthusiasts and those with potted plants.

One of the standout features is its slow-release formula, which can feed plants for up to 8 weeks, reducing the frequency of applications and saving time for busy gardeners. This fertilizer is synthetic, which means it may work quicker but lacks the organic composition some gardeners prefer for maintaining long-term soil health. 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.

The BIOADVANCED 12-Month Tree and Shrub Protect and Feed is a multifunctional product designed to both nourish and protect your Arborvitae and other trees or shrubs. One of its standout features is its long-lasting protection; a single application can fend off insects like Japanese Beetles, Emerald Ash Borers, and Aphids for up to a year. This makes it very convenient for busy gardeners who prefer less frequent maintenance.

Additionally, the slow-release fertilizer helps improve the health of your plants over time, ensuring they receive a steady supply of nutrients. The product’s systemic protection ensures that each part of the plant, from roots to leaves, is safeguarded against potential threats. However, it's important to note that this product is not organic; it is a synthetic fertilizer and insecticide, which might not appeal to those looking for a natural gardening solution.

Furthermore, it cannot be used in certain states like Connecticut, Colorado, Maryland, and Vermont due to regulatory restrictions, so availability might be an issue depending on your location. Another downside might be the weight and size, as the gallon container might be cumbersome for some. For those looking for a robust, all-in-one solution to protect and feed their Arborvitae and other shrubs with minimal effort, this product is a strong candidate, provided they are comfortable using synthetic options and it is permissible in their state.

The GARDENWISE Evergreen Fertilizer is a versatile option for those looking to boost the health of their arborvitae and other acid-loving trees and shrubs. With an NPK ratio of 8-4-8, the fertilizer offers a balanced mix of nutrients that support root and foliage health, which is essential for the steady growth of evergreen plants. Its slow-release, granular formula ensures nutrients are delivered consistently over time, reducing the need for frequent reapplication, which is convenient for gardeners of all experience levels.

One of the product's primary strengths is its ability to cater to a wide range of evergreen species, from azaleas to pines and magnolias, making it an all-purpose choice for outdoor gardening. The inclusion of essential micronutrients further enhances the vitality and resilience of plants, which is crucial for maintaining lush, healthy foliage and strong roots.

Users should be aware that the effectiveness of this fertilizer may vary depending on the soil condition and its compatibility with the specific pH needed by their plants. While it's designed for acid-loving plants, the exact results can depend on the existing soil pH and nutrient levels.

The easy-to-use granular format minimizes mess and ensures even distribution when applied around the root zone. This feature, coupled with the product's origin from a reputed manufacturer, Summit Sales Company LLC, makes it a reliable choice. Though the product coverage isn't precisely defined and depends on specific soil and plant conditions, it remains a popular choice in the gardening community, making GARDENWISE Fertilizer a solid option for those seeking to enhance their arborvitae's growth and health with minimal hassle.
