Earthbox fertilizer question

roper2008 · March 27, 2017

What fertilizer's do you all use with your Earthboxes? I only have organic fertilizers, but
the earthbox instructions says they need to be between 5-15. All of mine are below 5.
I will probably experiment between the synthetic and organic, if I can find an organic
above 5.

Another question. I know I sound like a newbie, but pro-mix is too expensive to use in
my earthboxes. I bought a potting mix called Just Natural. I hope it will work well. It does
have worm castings, but probably not much that I have to worry about it. My local
Wal mart is selling it for almost $10 1 cubic foot, online for $6.77. I found it at Southern
States for $4.57 1 cubic foot.
