Burned my bushes, 12 of them. Hopefully some will survive. I will not use these again.

Best price I could find, decent shipping cost, came as described unbroken.

I have arborvitae trees in my yard. 33 of them to be exact. They did wonderfully last year and I wrapped them in burlap for the winter: upon removing the burlap they were emerald green and healthy: a week later I used these spikes to provide nutrients and foster growth. I read the packaging and followed directions placing the spikes outside the drip line. Now, almost 2 weeks later my trees are all dying, some Of them rust brown top to bottom. This is the only variable outside the norm and timing of using them and browning is aligned. I’m so upset I cried on my knees in the yard.

Too soon to tell, but I've used them before with great results.
