Slow-release, easy-to-use fertilizer stakes. Avoid over-fertilizing and wasteful runoff, while encouraging growth in fruit trees, ornamental trees, and shrubs. These pre-measured spikes work to gradually introduce nutrients into your soil. Gently tap stakes into the ground at the dripline (directly below the ends of the longest branches) to distribute elements to the root zone without risk of burning sensitive roots. Can be used up to 3 times per year during the growing season — spring, mid-summer, and fall. NPK: 8-11-11. Each package contains 5 stakes.

Usage: For new trees, use 1 spike. For older trees, use 3 spikes for every 2 inches of trunk diameter (diameter of trunk as measured at chest height).

Patty S on Mar 4, 2019
Have used these before--very easy to pound into the ground with a hammer, and the slow delivery of fertilizer and fixed size of the stake takes worry out of fertilizing too much or at the wrong time.

I am getting ready to plant my new pecan trees and noticed that in one place it said not to fertilize new trees then in another i saw to fertilize three times the first year. I wasn't sure when I should fertilize the new trees. when is it safe to fertilize?
Catherine R on Nov 5, 2016
BEST ANSWER: Thank you for your question. It's best to wait until spring to fertilize new trees. You don't know to encourage new growth just prior to the winter months, which will damage the tree.
Spike fertilizer stakes should you use these in the fall also?
Jim A on Oct 10, 2018
BEST ANSWER: We don't recommend fertilizing in the fall because it encourages new growth that will be killed by the first hard frost, putting a lot of stress on the tree/plant. It's best to wait until spring.
How long will they last?
tom m on Nov 29, 2018
BEST ANSWER: Hi, Tom. Each spike lasts about 1/3 of the growing season.
can we use these on nut trees also?
William on Apr 17, 2017
BEST ANSWER: Yes, In addition to Paws Paws. I have specifically used them Chestnuts and saw excellent growth from my trees.
Do you use these fruit tree fertilizer stakes on newly planted trees like peach and cherry trees?
Judith M. N on Apr 11, 2016

Just be careful of placement. You don't want to damage the roots.
are these good for persimmon?
Lourdes on Mar 28, 2019
BEST ANSWER: These are good for any kind of fruiting tree.
Can these be used for blueberry bushes?
MIKE N on May 30, 2018
BEST ANSWER: These are not the best choice because they don't contain any sulfur, an acidifying agent that keeps the soil pH lower (between 4.5 and 5.0). That is something blueberries need to survive and thrive. Stark Blueberry Fertilizer is a much better choice and is specially made only for blueberries: //
Why does most of the persimmon fall off the tree?
Mellina L on Aug 26, 2020
BEST ANSWER: I don???t have any persimmon trees, though they grow in our area (Zone 9B). They are too big for our space. I have used the grow sticks for the three citrus (dwarf and semi-dwarf), two peach (seni-dwarf) , one apple, one pear, and one apricot tree that I have in our back yard. All were planted between Oct. 2018 and this spring. I have made two years??? worth if peach and apricot jam and jelly. The apricot and peach jam was last year, and this year both peach trees came in with enough fruit to make about 24 jars. So the grow sticks work well as a timed release fertilizer.
The bare root tree I planted having new shoot came up 7??? above the ground. Should I cut them off from the lower of the stick (tree) ?
Rosita H on May 30, 2020
BEST ANSWER: We appreciate you reaching out to us. Yes this sounds like it may be a sucker and will need removed so it does not steal all the nutrients from your tree and hinder it from growing.

If you have any further questions please don't hesitate to reach back out to us. Have a great day!

Are these okay for potted fruit trees? Will it hurt the root system?
Samantha D on Jan 25, 2019
BEST ANSWER: That's a good question to ask. We recommend you use fertilizer spikes a little differently in a container - push the spike into the pot near the rim rather than in the middle of the soil and your tree will be very happy.
Is this a good fertilizing spike for fruiting Banana Trees (does it have plenty Potassium needed for them)?
Debra M on Jun 1, 2018
BEST ANSWER: This fertilizer is 8-11-11, which is perfect for banana plants. You don't want too much nitrogen. Be sure to stop fertilizing when the tree flowers.
What's better for a brand new pluot tree? This or tre-prep?
Elizabeth R on Apr 23, 2018
BEST ANSWER: Tre-Pep is actually better because of the number of micronutrients that focus on root development. The GroStakes are great for older trees; the formula is a little too concentrated for new/young trees.
