Miracle-Gro Evergreen Fertilizer Spikes, 3 lb., 12 Spikes, Easy-to-Use

Our Evergreen trees (redwoods) have been planted for almost 3 years, just surviving. This year we used the Evergreen Fertilizer Spikes as the Miracle grow instructed and wow, what a difference. My trees are now full and green. Needless to say, we will continue to use the spikes. I wish I had taken before pictures.

I bought this product quite a few years ago used as directed and it almost killed every one of my evergreens they slowly recovered many years later and recently I decided to try the product again and when I did following the directions even cutting the spikes in half to reduce the amount of fertilizer I install the half spikes at the drip line as directed roughly 2 feet or more from the roots one on each side of each tree and probably within two or three days every Evergreen I did this too is developing brown tips and dead branches I am besides myself what is wrong with this product???? I did exactly what was written on the directions If the manufacturer reads this review I hope he reaches out to me because I really don't understand what is going on with my evergreens
