My trees love this. The sticks are easy to install. Easy to transport a collection of sticks and go from tree to tree (I have 66) banging them into the ground. I use the sticks on shrubs as well as trees: what's left after each tree gets 2 or 3, the shrubs get.
The box is flimsy. 160 sticks weigh a lot (35+ lbs) . The box holds them but the box can't stand up to individual shipping & handling.
Great product. Just need to hammer in the fertilizer food spikes and you see an instant change as your trees and shrubs grow and flower.
Highly recommend, I will buy more.
