December 8 - Pat G. asks:

"I have read a couple articles regarding using your wonderful fertilizer recipe when planting a vegetable garden. Since the article and information I have looked at only talked about using this "mix" for a large open garden area, my question is once the mix has been put together, how much per 5 gallon bucket or yard of soil would I add to this of this mix? I am thinking maybe 1 cup per yard of soil for example but not sure. We are using 3 gallon pots this year on our deck for tomatoes and other veggies and want to mix your receipt and give it a try this way."

I don't recommend it for pots. The problem is most potting soil is sterile. Dry organic fertilizers require soil fungi and bacteria to break the components down into simpler compounds plants can actually use. I suppose it'd be possible to "inoculate" the potting soil by adding garden soil to it; but I'm not convinced that would work very well.

There are commercial organic liquid fertilizers available, though, and those work fine for pots. You can find them advertised on Territorial Seeds website or Johnny's Selected Seeds website, or even if you already know what specific fertilizer you want. You can probably also find them at your local garden center.

The fertilizer I'm currently using for my indoor pots is Liquinox "Grow" 10-10-5 [affiliate link]. It's an organic-based liquid fertilizer. I buy the concentrate to save money - it goes a long way. It's important to note that seed companies tend to change the brands they carry from year to year, so what you buy one year may not be available from the same place in the future... but as long as you look for a fertilizer with reasonably balanced NPK values and containing micronutrients, you should be fine.
