Purely Organic Products believes garden products should be good for plants and easy for gardeners too. Our Fertilizer Spikes are made with natural ingredients like molasses and soy. They’re rich in the nutrients needed for healthy trees and shrubs; they’re approved for organic use; and they won’t break, crush, or smash!

Plant Based Formula: Purely Organic Fertilizer Plant Food Spikes are derived from a high quality, plant based formula with molasses and soy protein hydrolysate. They're natural, organic and vegan with no harsh ingredients or harsh chemicals.

OMRI Listed for Organic Use: These Purely Organic Fertilizer Spikes are OMRI Listed and approved for use in all organic applications.

Fast Acting, Long Lasting, Robust Nutrition: Each 5 Inch TruSpike Fertilizer Spike is packed with nutrition designed for feed your trees, evergreens and shrubs continuously for up to 3 months. 

It's a TruSpike... Hammer It In! This is not your old, ordinary, crumbly, dusty, oval shaped fertilizer "spike". This is a patented, powerhouse TruSpike. There's no need for a plastic cap or special equipment with TruSpike, just hammer it in and let it get to work fertilizing your plants. It will NOT break, crush or smash... guaranteed!

Simple to use. For best results, feed 2 times a year -- early spring, and late fall -- for continuous fertilization. Depending on climate and plant variety, an additional application in the summer can provide extra nutrition and help protect from summer stress.

Nutrient Rich 7-0-2 Formula with natural ingredients contains 7% Nitrogen for plant growth and color; and 2% Potassium for strong roots. Fertilizer spikes release nutrition directly into the root zone to help promote stronger trees and shrubs without over-fertilizing or runoff.

For best results, feed 2 times a year -- early spring, and late fall -- for continuous fertilization. Depending on climate and plant variety, an additional application in the summer can provide extra nutrition and help protect from summer stress.

Water well before application.

Using a hammer, drive each spike into the soil until the top is at least 2 inches below the surface. Evenly space spikes in a circle along the dripline.

Never insert closer than 30 inches from the trunk.

For shrubs 1 spike per 3 feet of plant height is recommended.

For trees measure the trunk diameter 1 foot above the ground; and use 1 spike per inch of diameter with a minimum of 2 spikes.

Important Note: The instructions above are for use as a guide only. For complete instructions for use and safety precautions review the back of your product package and the manufacturer's Material Safety Data Sheet.

What Is The Dripline? The drip line lies along the outermost circumference of a tree's branches. Spikes should be evenly spaced in a circle along the drip line. For small trees and shrubs, with a drip line closer than 30 inches, insert spikes 30 inches away from the center, at least 3 feet apart.

Me agradó, fácil de usarlo

Do you have a dog?

I was looking forward to seeing my trees fill out. Unfortunately I have to dig them all up. My dog managed to dig one up in the late afternoon to munch on & didn't want to give it up. He's still looking for more.

Easy to put in ground

Good for trees

Fast Delivery!

Works very well. I used it for my front of the house tree. Within 2 weeks I was able to notice a huge improvement on the tree. Growing fast and blooming.

Hope it grows

Used this for a mountain ash that was looking poor time will tell if it works

Quick improvement

Texas soil is not plant friendly for the most part. These fertilizer were amazing for trees, shrubs and flowers. I keep buying it over and over again

Your Trees Will Love it!!

We bought these fertilizer spikes to give our recently planted trees (3 years ago) a jumpstart this spring and are so glad we chose Purely Organic!!! The spikes were super easy to hammer into the ground, no chalky dust flying into the air like other products. The trees are loving the fertilizer and are blooming earlier and fuller than ever before. It is still early in our season but our little trees are ahead of the well established native trees around them. We LOVE Purely organic products!! If you have not used the organic lawn food you need to try this as well.
