10 Best Fertilizer For Arborvitae 2025 in the United States

Miracle-Gro Tree and Shrub Plant Food Spikes are designed to promote vibrant color and foliage in various trees and shrubs, including arborvitae. These spikes are easy to use, as they are inserted directly into the soil around the tree’s drip line, delivering nutrients straight to the roots. This ensures efficient feed and minimizes wastage.

The recommended application is twice a year, in spring and fall, making it a low-maintenance option for busy gardeners. The product is suitable for deciduous, flowering, and evergreen trees, and it’s especially beneficial for acid-loving plants. This versatility makes it a good choice for a range of gardening needs.

The fertilizer is synthetic, which could be a consideration for those preferring organic options. Additionally, using spikes requires proper spacing to avoid over-fertilizing, which may be tricky for some users. With a package of 12 spikes, it is sufficient for feeding multiple trees or shrubs. This product would particularly benefit gardeners looking for an easy, effective way to nourish their evergreen and other types of trees without frequent applications.

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.
