Here's the miracle grow product I am using.
Miracle-Gro Shake & Feed
Shake & Feed takes the guesswork out of feeding - simply shake on in minutes and feed your plants continuously for up to 3 months. Great for use on all types of new and existing outdoor flower and vegetable beds, trees and shrubs.
I worked it into the soil in my tomatoes, peppers, and cucumbers and plan to do the same with the hop rhyzomes when I get them. I also add more topsoil, potting soil, and lots of manure to the native soil. Using this method I have not yet lost a plant and can get production from the fruiting plants up until October.
