Excellent cost, delivery, and ease of use
We are submitting this review without the benefit of seeing the fertilizer effect on our trees and plants. The price, time of delivery, directions, and ease of use were excellent. We have used a competitor's spikes through the last 4-5 years, and the SimplyGro spikes are much easier to put in the ground, due to the size and firmness of the spikes. The spikes have what seems to be an excellent composition of things necessary for fertilizing. The cost is also very competitive. We will submit additional info during the growing season.
