I have very little experience growing things in raised beds. I know you don't use row spacing with them like you would use row spacing if you were doing a plot in the ground.

I know this means since you don't need row spacing, you can plant things closer together in a raised bed. However I also know if you overcrowd plants, you stress them out, and they're more prone to disease and bug infestations, which results in a reduced and/or no harvest as a result.

So I'm trying to figure out how much of each veggie listed below could I plant in a 4 x 8 raised bed without overcrowding the plants? (Just to clarify, no I'm not going to be planting all of these vegetables at the same time, nor are they going to be planted all in the same bed).

root veggies (carrots, beets, potatoes, turnip, and daikon; NOTE: I don't know how many people are familiar with daikon, it's a large white Asian radish, you typically use 6" spacing per plant for it)

Tomatoes

Eggplant, Peppers

Zucchini

Watermelon, cantaloupe (the varieties I am planting will be bush; I don't have much experience growing watermelon and cantaloupe, so I don't know if these bush varieties will actually be compact, or if they'll sprawl like typical melon plants that aren't bush varieties). In regards to the watermelon and cantaloupe varieties, the names of the varieties I'm growing are called minnesota midget and Sugar Bush (a sugar baby variety).

Leafy green veggies (spinach, arugula, lettuce, kale, Asian greens; NOTE: again with Asian greens I don't know how familiar people are with them...the ones I want to grow would be pak choi and bok choi, komatsuna, and tatsoi)

Cabbage (normal green cabbage and napa cabbage)

Beans (snap beans and lima beans; I haven't decided yet whether I'll be doing pole beans or bush beans).
