Outdoor Gaia Green 444/284 flower spike?

I don’t mix mine in at the depth of 2 feet. I work it into the top soil bout 2” and water in, as long as its being kept moist the microorganisms will break it down n make it available. Could add a layer of mulch to keep it from drying out. Hay or cut grass also works. I do find Gaia green lacks Mg and needs more K, so they have green sand or a kelp extract thats high in K from the same brand, Epsom salts are an option for Mg thats dirt cheep, As for burning, yea you can burn it, don’t give to much, and if you want to add more give it a week or two before adding more in. Good Luck!
