MSU Soil Test.com gives you several options as to the amount of fertilizer to apply to a 1000 sq feet. You did not indicate the surface area to be covered. The package label gives you the amount of Nitrogen(N), Phosphorus(P),Potassium(P). A majority of garden centers, hardware stores, and large chain stores carry phosphorus free fertilizers. Lawn fertilizers can be used but be sure they are free of herbicides. The Miracle Grow Plant Food you already have may work and can be watered into the soil but it doesn't last very long. You may want to side dress your plant with a slow release fertilizer. Read package labels and follow directions for application. MSUsoiltest.com has a fertilizer calculator which will help you determine the amount of fertilizer to apply to the size of your garden. There is also a good article attached on application of fertilizers. We do recommend name brand for you to buy.
