I thin out at about two inches, but for example tomatoes, recently
repotted, have not yet been thinned at 4 inches. I am waiting to see
which ones survive the repotting best.

If you are planting intensively (no rows), the distance between plants
should be

- 1 ft broccoli
- 2 ft tomatoes, cabbage
- 3 ft zucchini
- 3 inches carrots, parsnips, spinach
- 6 inches onions
