The Old Farmer's Almanac TruSpike Tree & Shrub Fertilizer Spikes — 12 Spikes, 3 Lbs

Overview

The Old Farmer's Almanac Tree & Shrub Fertilizer Spikes bring a time-honored approach to nourishing established trees and shrubs. The patented TruSpike design is crafted for easy hammer-in installation and is built to stay intact without crumbling or leaving dusty residue. Made in America, these spikes reflect a heritage of practical horticulture paired with modern formulation.

What’s inside and how it helps

• Nutrient-rich 13-3-3 formula: 13% nitrogen supports vibrant growth, 3% phosphorus supports flowering and fruiting, and 3% potassium strengthens roots.
• 5-inch TruSpike design: robust, easy-to-drive into soil, and designed to feed for months without the need for a cap.
• Direct root-zone nutrition: nutrients are released where plants need them most, minimizing waste and runoff.

How it works and what you can expect

The spikes deliver steady nutrition to the root zone, helping trees and evergreens maintain color and resilience. By focusing release directly at the root zone, you may notice more robust growth and healthier canopies over time, especially when used as part of a seasonal feeding routine.

Usage guidance for best results

• Two feedings per year: early spring and late fall, aligned with typical plant growth cycles.
• Optional summer feeding: in warmer climates, a mid-summer application can help plants weather heat stress.
• Simple application: hammer the spike into the soil around the drip line or base of the plant; no caps or special tools required.

Why this matters

Since 1792, The Old Farmer's Almanac has paired practical gardening guidance with American science. These fertilizer spikes reflect that approach—easy to use, American-made, and designed to support healthy trees and shrubs without fuss.
