How to mix fertilizer concentrate
I have a bag of Plant Marvel: "General Purpose 20-20-20 PLUS Specially formulated as a general purpose feed for use on ornamental plants, small shrubs, grasses, fruits and vegetables, and other intensely cultivated crops."
I'd like to use this up since I have almost 40 pounds of it. I will purchase Dyna-Gro next time I need fertilizer.
I'd like to mix up this fertilizer into suspension so it is easy to mix with my watering can. You need to use hot water with this product to get it to mix well, but it is suppose to stay in suspension well once mixed.
How can I go about figuring out how much to mix, then how much to use?
I have one of those Miracle Gro bottles where I use 1/3 of a cap per gallon. I would like to make it up at that same concentration if possible.
Any suggestions on how I calculate the amount I mix, then how much of that liquid I use when I water?
