10 Best Fertilizer For Trees And Shrubs 2026 in the United States

The Scotts Evergreen Flowering Tree & Shrub Continuous Release Plant Food is designed specifically for acid-loving trees and shrubs such as evergreens, dogwoods, and hydrangeas. It aims to promote healthy root growth and lush foliage, which is crucial for maintaining vibrant and healthy plants. A notable strength of this product is its continuous release feature that feeds plants for up to two months, reducing the need for frequent reapplication.

Its direct soil application method is particularly easy for users, making it a convenient choice for those who prefer a hands-off approach. The fertilizer is safe for plants when used as directed, minimizing the risk of burning, which can be a concern with some fertilizers. With a customer rating of 4.6 stars and no discontinuation by the manufacturer, it is well-received within its category.

Its medium coverage might suit smaller gardens but could require more for larger landscapes. While the seasonal adaptability isn't explicitly mentioned, its extended feeding period might cover some seasonal growth needs. This product appears to be a suitable choice for homeowners looking for a straightforward, low-maintenance fertilizer option for specific tree and shrub species.

Miracle-Gro Tree and Shrub Plant Food Spikes are designed to provide essential nutrition to your trees and shrubs. These spikes are particularly user-friendly, as they are inserted directly into the ground, thus delivering nutrients directly to the roots. This makes the application process straightforward and minimizes mess, which is a significant advantage for those who prefer low-maintenance gardening solutions.

The spikes are suitable for a wide variety of trees and shrubs, including deciduous, flowering, and evergreen types, which adds to their versatility. Additionally, they are formulated to be used twice a year, in the spring and fall, aligning well with seasonal growth cycles for optimal effectiveness. This can help ensure your plants look vibrant throughout the year with minimal effort on your part.

On the downside, the number of spikes required per tree can add up, especially for larger trees with a 12-foot drip line diameter, potentially making it an expensive option for those with multiple large trees. Another consideration is that these spikes are synthetic, which might not appeal to those who prefer organic gardening methods.

The Jobe's 01611 Evergreen Tree Fertilizer Spikes come in six packages, each containing 15 spikes, providing a convenient option for ongoing tree care. With an N-P-K ratio of 13-3-4, these spikes deliver a high amount of nitrogen to promote strong foliage growth, moderate phosphorus for root development, and potassium for overall health.

The fertilizer is provided in stick form, making it easy to apply by inserting the spikes into the soil near tree roots. This method offers a slow, steady release of nutrients throughout the year, reducing the need for frequent applications. These spikes are best suited for medium coverage areas and are especially beneficial for evergreen trees that require a consistent nutrient supply across multiple seasons.

For gardeners seeking simple, low-effort feeding to support tree health throughout the year, Jobe's fertilizer spikes offer a practical solution with reliable nutrient delivery. However, those looking for fully organic fertilizers or specific micronutrients like iron or magnesium might consider alternative options, as this product is a synthetic formulation designed for targeted feeding.
