  • Easy to use
Easy to use, these Old Farmer's Almanac fertilizer spikes are easier to use than the brand I used before. They stay intact even when I use a mallet to bang them into clay soil. It will be summer before I know if they were good for my shrubs and trees. Here's hoping.

  • Tree and Shrub Fertilizer Stakes--Fertilizer Stakes that Deliver.
13-3-3 fertilizer stakes for your shurbs or trees. Supports health plant growth and health. The are advertised as "will not break or shatter" when being driven into the ground--and the claim is true. Thats a real plus. Should help your shrubs and/or trees green up. A good value

  • These were ok
Not bad. Not the easiest to hammer into the clay soil we have here but I got the job done.

  • Does the job
After hurricane these helped my trees green up nicely. Easy install but crack and break a lot when installing. Would dig the hole before I would try to drive in with hammer for best results.

  • Good quality material
I just received these and I've not got the opportunity to put these in the ground yet, but the quality of material/stakes do look good. There definitely are fertilizer in them because the smell of ammonia nitrate/urea is there without a doubt

  • Easy to install
I see some complaining about difficulty installing these spikes. I found a very easy method. I use a small pickax and with one swipe of the pointed end I create a hole about 8 inches deep, put the spike in and just press down on it with the pickax inverted.. The spike disappears down the hole below ground level. I installed 12 spikes in about six minutes. ... show more

  • Don't split while you pound them in
My trees seem to be very happy with these spikes. They stay together when you pound them in!

  • Nice for tree use.
Fertilize my large trees with them. Use a steel spike to predrill for fertilizer spikes.
