Miracle-Gro 100376 Fertilizer Spikes for Evergreens 12 pack
I bought some small Emerald Green arborvitae. I have used fertilizer spikes diligently every spring and fall. Two of them even blew over in one winter storm and I had to pull them back up and stake them. The spikes do the trick. They are green and healthy. I find Miracle Grow products work well. The nice thing about spikes are that they are a once and done, as they are time released. $9.97 at Amazon.
