Miracle-Gro Tree And Shrub Plant Food Spikes

Miracle-Gro Tree & Shrub Plant Food Spikes provide slow-release nutrients directly to the roots of trees and shrubs, which helps support vibrant color and healthy foliage. The spikes are designed for use with deciduous, flowering, and evergreen trees, as well as acid-loving plants like hydrangeas, azaleas, and magnolias. This formulation aims to supply ongoing nourishment without frequent applications, making it a practical option for pine and other conifer care where consistent root feeding matters. The product’s emphasis on direct root delivery minimizes nutrient loss and helps ensure nutrients reach the root zone where pines actively absorb them.
SimplyGro Fertilizer Spikes For Evergreen Trees & Shrubs

Designed specifically for evergreens, SimplyGro’s 24 spikes use a 12-3-3 formula to support pines, firs, and other conifers. Each spike is a pre-measured dose that feeds over several weeks, reducing the risk of over-fertilization. The product is structured for a twice-yearly application pattern—spring and fall—to align with periods of rapid growth and energy storage. The formula aims to sustain lush foliage and vibrant color while helping minimize nutrient runoff into waterways, preserving local ecosystems. This makes it a practical, environmentally mindful choice for pine landscapes seeking steady root nourishment.
Jobe’s Slow Release Evergreen Fertilizer Spikes

The Jobe’s Evergreen Fertilizer Spikes are tailored for cypress, arborvitae, pine, cedar, and other acid-loving trees. The 11-3-4 NPK composition provides a continuous nutrient supply at the root zone, helping support evergreen needle color and overall vigor. Designed to minimize runoff and odors, these spikes are intended for twice-yearly application—early spring and late fall. The slow-release format reduces the risk of fertilizer burn while delivering sustained nutrition for pine trees, contributing to steady growth and resilience against environmental stressors.
Jobe’s Evergreen Fertilizer Spikes (15-Pack)

Jobe’s 01661 Evergreen Fertilizer Spikes are specifically formulated for evergreen trees and shrubs. The 13-3-4 ratio supports a steady nutrient supply below the surface, where active roots grow. This slow-release approach minimizes waste and reduces the risk of nutrient runoff. Application is simple and recommended twice yearly, in early spring and late fall, making it convenient for pine maintenance where consistent feeding can support needle retention and overall evergreen health. The 15-pack option provides a longer feeding season for larger landscapes or multiple pine specimens.
SimplyGro Fertilizer Spikes For Evergreen Trees & Shrubs (12 Spikes)

This SimplyGro option mirrors its evergreen-focused formula with a 12-3-3 balance designed for pines, firs, and other conifers. The spikes are pre-measured to promote even feeding and reduce the chance of over-fertilization. With a recommended two-application yearly schedule—spring and fall—these spikes aim to sustain lush foliage, conifer resilience, and steady growth. They’re positioned as a smarter, low-risk feeding method that targets root nourishment directly to minimize environmental impact while supporting evergreen health over the growing seasons.
Buying Guide: Pine Tree Fertilizer Spikes And What To Consider
Effective fertilizer spikes for pines share common goals: deliver nutrients where roots need them, minimize runoff, and fit your maintenance schedule. When choosing among options, consider the following factors:
- NPK formulation: Evergreen-focused spikes often use formulas like 13-3-4 or 12-3-3. Higher nitrogen supports green growth, while balanced phosphorus and potassium aid root development and stress resilience. For pine trees, look for nitrogen-rich blends paired with adequate potassium for needle health.
- Slow-release design: Spikes that release nutrients over several months help prevent burn and reduce application frequency. This is especially important in soils with variable moisture or high drought risk.
- Root-zone delivery: Spikes buried at the tree’s root zone ensure nutrients reach active roots. Avoid products that rely on surface feeding, which can be washed away by irrigation or rain.
- Application frequency: Many products recommend twice-yearly feeding in spring and fall. Consider your local climate and pine growth cycle when planning applications.
- Environmental impact: Look for pre-measured spikes and formulations designed to minimize nutrient runoff. Environmentally mindful options help protect waterways and local ecosystems.
- Tree and shrub compatibility: Ensure the spikes are suitable for evergreen species and acid-loving plants if you’re feeding pines alongside nearby hydrangeas or rhododendrons.
- Pack size and coverage: Larger landscapes or multiple pines may require several packs. Check how many spikes per tree and total coverage per package.
- Ease of use: Hammer-in or easy-to-insert designs reduce handling difficulty, especially for deeper root zones.
