plant spacing for veggies

Basically, it's the only way I know how to describe what I'm asking.

There are recommendations of how much to plant, but this is referring to doing it via a plot in the ground.

These recommendations are fine for that, but with container gardening, it makes no sense.

Below is a list of what the planting guidelines are. I know they're general, but it's basically what I could find.

Beets-a 10 foot row
Carrots-a 10 foot row

Greens (spinach, mustard greens, swiss chard, argula, mizuna [japanese mustard green], bok choi [chinese cabbage], pak choi [miniature variety of bok choi] and basically any other leafy green thing you can think of applies here) a 10 foot row

Onions (red,yellow, white; as well as sets-shallots, scallions, etc.) a 5 foot row, 'single plantings' (what does this mean? I don't know)

Turnips-a 10 foot row

Leaf lettuce-10 foot row

Radishes-a 5 foot row (successive plantings-I'm assuming it's referring to red radish only). It doesn't specify how much to plant for white radishes (large, white asian; milder in flavor, bigger in length and take longer to mature)

Somebody recommended figuring out the square footage based on what the size of the container is. Unfortunately I don't know how to do that because I'm really bad with math.

Size containers I use are 5, 10, 20, and 30 gallons. I don't know off the top of my head what the dimensions for them with length, width, and height are. Is this info necessary to find square footage?

Also I'm wondering how many squash plants to plant for enough for 2 people

The type of squash I'm referring to is....

Kabocha (Japanese asian pumpkin, much smaller than American pumpkins)
Pie Pumpkins (small ones ideal for making puree)

Can somebody help me with converting these measurements with a plot to something that would make sense for container gardening? What exactly is the 'formula' for making the calculations for the conversion of row spacing in a plot to something for containers?

Below is what I'm referring to:

RE: plant spacing for veggies

Toward the end of last summer I started using the planting guides for square foot gardening in my containers. I had trouble getting my root crops to form subsurface bulbs. Can't say that it helped with them, but I still feel the spacing is probably closer to what will work for containers.

You can find a list of planting guides for square foot gardening by doing a computer search for the info. Hope that helps.

RE: plant spacing for veggies

Kawaiineko, a good working guide is to think of the end product. Carrots, a long, tap-root crop, will require a different spacing from lettuce or other leaf crop.
For the carrot, it is best to confine the root room to discourage root branching. I have seen beautiful carrots grown in sections of 6" clay pipes set upright and filled with a good potting soil. 3 or 4 seeds were sown and the seedlings thinned out to a single plant which was grown to maturity.
For an above ground crop think of its "canopy" or spread. The objective is to have the leaf edges of the mature plant just touching, thereby completely utilizing the available area. Thus the more upright growing "Bok Choi" can be more closely spaced than say, mustard or cauliflower. I once mystified passers-by who thought that a watermelon vine was growing out of a rock-pile. I had sneaked an 'earthbox'-sized planter with seedlings into the apex of the pyramidal heap. Over time the vines completely covered the rock-pile and water-melons were available for the taking. The point is that for a vine crops, comparatively little root room is required but a great deal of surface area.
I hope that this helps.
