Allow 10 to 12 inches on all sides between head lettuces. Corn does best in blocks for pollination purposes and should be planted about 12 inches apart in raised bed blocks or rows. Tomato plants require 12 inches of space on all sides, while peppers, potatoes and cabbages need roughly 15 to 18 inches of space.
Also know, how far apart should plants be in a garden?
Rows should be 24 to 36 inches apart. You can use double rows 10 inches apart, with each double row 36 inches apart, if space is limited. You can also do this with carrots, lettuce, onions, radishes, English peas, and other early crops.
One may also ask, what happens if you plant vegetables too close together? Instead, the trees grow wider and fuller because of ample sunlight. Plants also can affect how nearby companions grow, as roots tangle and compete for the same resources of water and nutrients in the soil. Planting too close together limits the growth potential and often threatens plant health.
Regarding this, how much space should be between vegetable rows?
18 to 36 inches
Can you plant vegetables closer together in raised beds?
In a raised bed or interplanted garden, plants are grown more closely together than in a traditional row garden. When growing vegetables, herbs or fruits, stagger your rows so that a plant in one row is between two plants in the other row.
