Jobes Evergreen Tree Fertilizer Spikes 90-Count (6×15) 13-3-4 Slow-Release Stakes for Stronger Roots

Jobes 01611 Evergreen Tree Fertilizer Spikes are slow-release nutrient stakes that deliver a full year of balanced feeding beneath the soil to support stronger root development in evergreen trees and shrubs.

These spikes come as six 15-count packages (90 spikes total), each formulated at 13-3-4 N-P-K to steadily supply essential nutrients where roots can readily absorb them. Designed to be inserted around the dripline, the spikes dissolve gradually, simplifying maintenance compared with repeated granular or liquid applications. They are intended for use on a wide range of evergreens and ornamental shrubs to promote steady growth during the growing season.

How do these spikes feed my evergreen trees?

The fertilizer spikes release nutrients slowly into the soil over many months, placing fertilizer directly in the root zone for efficient uptake. That reduces waste from surface runoff and minimizes the frequency of reapplication compared with soluble fertilizers.

• Slow-release 13-3-4 formula supplies nitrogen, phosphorus, and potassium.
• Inserted beneath the surface at the dripline for direct root access.
• One application lasts through most of the growing season.

Where and how do I place the spikes for best results?

For optimal nutrient delivery, place spikes evenly around the tree at the dripline — the area directly under the outermost branches — where feeder roots concentrate. Push them into the soil to the recommended depth, spacing them according to trunk diameter or package directions so roots of different ages access nutrients uniformly.

• Position spikes around the dripline for maximum root contact.
• Follow package spacing guidelines based on tree size.
• Insert spikes into moist soil for easier placement and faster dissolution.

How many spikes will I need and what does this 6-pack provide?

This product includes six packages of 15 spikes each, totaling 90 slow-release stakes—enough for multiple trees or season-long feeding of several specimens. Small trees and shrubs require fewer spikes; larger trees need more, so plan placement by trunk diameter and canopy size.

• Six packages × 15 spikes = 90 spikes total.
• Use spacing recommendations to calculate per-tree needs.
• Good for homeowners managing multiple evergreens or for seasonal restocking.

Are these spikes safe and easy to use in home landscapes?

Designed for backyard and landscape use, the spikes are user-friendly and avoid mess associated with powders or liquids. They dissolve below the surface, reducing contact with pets and people, but always follow label directions for safe handling and storage.

• Premeasured stakes reduce overapplication risk.
• Below-surface placement lowers exposure and runoff.
• Simple to store and apply—no mixing required.

Who is this for: Home gardeners, landscapers, and property managers who want a low-effort feeding solution for evergreen trees and shrubs will find this 6-pack convenient. It suits users who prefer a measurable, slow-release fertilizer to support root development over the growing season without frequent reapplications. If you maintain multiple evergreens or plan seasonal care, the 90-spike supply helps cover several plants or multiple treatment cycles.
