Jobe's Tree Fertilizer Spikes 16-4-4

I used these when I lived in the US and they were great. So glad I finally found them in the UK,, but they are more expensive here. Regardless, they do a great job feeding the trees and shrubs and I will continue to use them.

Have been using for many years and works well

Tree spikes are easy to use and effective at fertilizing trees.

We have bamboo and Japanese maples is large pots, these have made a huge difference for the plants! The were yellowed and not very full in the spring, but within a few weeks with the plant spikes, they had greened up and filled out very well. Highly recommend this product

These seem to be effective. It's very hard to give a definitive review since trees take so long to show change. I have noticed that the leaves are greener in comparison to other trees in the same area.The package directions for putting them in the ground was written by someone who never tried his or hers own instructions. YOU CANNOT DRIVE THEM IN WITH A HAMMER!!! They will crush and have little value afterward. I would recommend using an implement to make a hole with, then dropping the fertilizer stake in.

These were easily driven into the soil using a rubber mallet without crumbling. Our tree seems to be growing well.

This is an easy way to fertilize my trees. I do not try to pound them into the soil as even with the plastic cap that comes with them is some protection, they usually start crumbling after a few blows. I use a long, narrow trench shovel to split the soil making them easy to insert deep in the ground for continuous feeding.
