Ideal for backyard fruiting trees and ornamental citrus alike, with simple, repeatable use.
Jobe’s Slow Release Evergreen Fertilizer Spikes
These evergreen-specific spikes are formulated with a 13-3-4 NPK ratio to provide a continuous nutrient supply just below the surface where roots are most active.

Buying Guide: Key Considerations for Tree Fertilizer Spikes
When choosing fertilizer spikes for trees, consider these factors to match your landscape needs:
- Tree type compatibility: Ensure the spike formulation aligns with deciduous, evergreen, fruit-bearing, or acid-loving trees in your yard.
- NPK ratio: Higher nitrogen blends encourage foliage, while balanced blends favor overall growth. Fruit trees may benefit from higher phosphorus or potassium during fruiting seasons.
- Release profile: Slow-release spikes minimize nutrient leaching and irrigation washout, delivering steady feed over weeks or months.
- Application cadence: Some products recommend twice-yearly applications (spring and fall), while others provide longer feeding windows. Plan around your local climate and tree growth cycles.
- Root-zone placement: Spikes should be placed near the tree’s drip line to reach active roots, avoiding direct contact with trunks to prevent damage.
- Environmental impact: Choose products formulated to reduce runoff and protect waterways, especially in areas with heavy rainfall or irrigation.
- Ease of use and mess: Spikes are designed for simple installation, with less chance of over-fertilization compared to granular mixes surfaced around the base.
- Organic vs. synthetic options: If you prefer organic or organic-rich blends, verify the product labeling to ensure it meets your standards for sustainable landscaping.
- Special notes for citrus and fruit trees: Some formulas are tailored for fruit production and may require seasonal timing to maximize yields.
In practice, select two to three products that cover evergreen and fruit-tree needs to create a balanced feeding plan. Always follow the product’s specific installation instructions for best results and to protect surrounding plant life and soil health.
