Evergreen fertilizer spikes are specially designed plant food sticks that deliver nutrients directly to the roots of your evergreens. These innovative spikes ensure your evergreens—including popular choices like arborvitae and pine trees—receive a steady supply of essential nutrients for optimal growth. They are easy to use and create minimal mess, making them an essential part of any gardener’s toolkit.
Why Use Evergreen Fertilizer Spikes?
Evergreen fertilizer spikes provide multiple benefits that contribute to the health and vibrancy of your trees and shrubs. Here are key reasons to consider using these spikes:
-
Direct Nutrient Delivery: Unlike traditional fertilizers that may wash away or be absorbed poorly, fertilizer spikes are inserted directly into the soil, delivering nutrients where they’re needed most—the root zone.
-
Slow Release Formula: Many evergreen fertilizer spikes, such as those from Jobe’s, are designed to release nutrients slowly over time. This ensures that your plants receive a consistent supply of essential elements like nitrogen (N), phosphorus (P), and potassium (K), which are vital for healthy growth.
-
Convenience: Using fertilizer spikes eliminates the mess of granular fertilizer and the need for complicated application methods. Simply drive them into the ground, and you’re done!
-
Reduction of Waste: Fertilizer spikes minimize runoff and nutrient loss by delivering nutrients directly into the soil where roots can access them, avoiding wasteful runoff commonly associated with liquid fertilizers.
How to Use Evergreen Fertilizer Spikes
Utilizing evergreen fertilizer spikes is simple. Follow these steps for optimal results:
-
Choose the Right Time: Apply the spikes in early spring and late fall when the plants are preparing for active growth or heading into dormancy.
-
Determine Spike Placement: Measure the diameter of the tree’s drip line (the area directly below the outer circumference of the tree branches). Space the spikes evenly within this circle, ensuring they are placed approximately 1-2 inches deep for optimal nutrient access.
-
Quantity: Generally, it’s recommended to place 1 spike for every foot of height of the tree or shrub, up to 5 spikes for bigger trees. However, many brands offer specific instructions for their products.

FAQs about Evergreen Fertilizer Spikes
Q1: How often do I need to apply evergreen fertilizer spikes?
A: It is recommended to apply spikes twice a year—in early spring and late fall—to ensure that your evergreens receive adequate nutrients throughout the growing season and into their dormant period.
Q2: Can I use fertilizer spikes for other plants?
A: While these spikes are specifically formulated for evergreens, many brands offer specialized spikes for different types of plants including flowers, shrubs, and vegetable gardens. Be sure to check the labeling on the product for specific applications.
Q3: What should I do if the ground is dry?
A: It’s essential to dampen the soil before inserting the fertilizer spikes. If the ground is hard or dry, watering it a day prior can help ensure easier insertion and improve nutrient absorption.
Q4: Are there any ecological considerations when using fertilizer spikes?
A: Using fertilizer spikes, especially those that minimize runoff and nutrient waste, is generally considered a more eco-friendly method compared to traditional granular or liquid fertilizers, as they reduce the chances of water contamination.
Q5: Can I use these spikes on newly planted trees?
A: Yes, evergreen fertilizer spikes can be beneficial for newly planted trees, provided that they’ve established some roots. Typically, it’s advisable to wait until after the first growing season before supplementing with fertilizer to encourage root development.
Conclusion
Evergreen fertilizer spikes are an invaluable tool for any gardener looking to enhance the growth and health of their evergreen trees and shrubs. With their convenience, targeted nutrient delivery, and minimal waste, they provide an effective solution for maintaining lush greenery in your landscape. Whether you’re a novice gardener or a seasoned professional, incorporating these fertilizers into your regimen can yield impressive results for your outdoor space.
