Where to Use: Use these spikes for all your outdoor, in-ground deciduous and evergreen trees and shrubs.

Types of Plants: Perfect for all deciduous and evergreen trees and shrubs including acid-loving plants.

How Often to Use: Apply once in the spring and once in the fall.

  1. Water First: Give the soil around your tree or shrub a good watering to soften it up before you start.
  2. Find the Dripline: The dripline is the area of ground under the outermost branches of your tree or shrub. Measure the diameter of the dripline to determine how many plant food spikes you'll need.
  3. Space them Out: Space the spikes at least 3 feet apart, evenly around the dripline.
  4. Drive in the Spikes: Gently hammer a spike into the ground using a rubber mallet until it is below the soil surface.

The number of spikes you'll need depends on the dripline diameter of your tree or shrub:

  • 4 ft. diameter = 1 spike
  • 6 ft. diameter = 3 spikes
  • 8 ft. diameter = 5 spikes
  • 10 ft. diameter = 7 spikes
  • 12 ft. diameter = 10 spikes
  • 15 ft. diameter = 16 spikes

After you've placed the spikes, just continue with your regular watering routine for your trees and shrubs.

A Good Habit: We always recommend wearing gardening gloves when you're working in the garden, and it's a good practice to wash your hands when you're done.

Frequently Asked Questions

How do I store leftover product?

Just close up the package and keep it in a dry spot, like your garage or garden shed, away from kids and pets.

Spikes are a great way to get fertilizer right down to the roots of your trees and shrubs, where they can use it most effectively. This ensures a continuous feeding for the whole season.

The dripline is the imaginary circle on the ground directly below the tips of the outermost branches of your tree or shrub. It's where the most active roots are, so it's the perfect place to feed.

These spikes are designed for in-ground trees and shrubs. For your potted plants, we recommend using our Miracle-Gro Shake 'n Feed Flowering Trees & Shrubs Plant Food.

Rated 5 out of 5 by from Convenient application I have not been able to use this product yet, but I'm very excited to do so. I received it far in advance of the directions to apply. I will know in a few months if it works! I do love that it seems very easy to use!

Rated 5 out of 5 by from Works really well I used these right at the start of the season and I’m getting fresh growth on my struggling hydrangeas. They are easy to use and I feel they work pretty quickly!

Rated 5 out of 5 by from Happier garden already! Easy to pop in the ground and great results already. I used the spikes on my hydrangeas and am impressed already with the added growth this year. Hoping this will influence big blue blooms as the spikes promote acid-loving plants and their unique features. It would be nice to have resealable packaging for easier storage, as I didn’t use all of the spikes- however they fit easily into a standard sandwich bag.

Rated 5 out of 5 by from Thanks Mircale Gro!! The spikes are easy to use as I just needed to make a small hole with a hand shovel. All of the spikes were intact and consistent in size and shape. The directions are straightforward and I like that they continue to feed throughout the season. My arborvitae like them so far!
