How Far Apart Should Vegetable Plants Be?

Start with the plant and method

• Tomato guidance distinguishes vining plants and supported growing habits. [1]
• Lettuce spacing changes when the goal is baby leaves rather than full-size leaf or head lettuce. [2]
• Cucumber guidance distinguishes spreading vines, hills, bush forms, and trellised systems. [3]

Plant spacing and row spacing are different

Plant spacing is the allocation along a row. Row spacing is the allocation from one row to the next. An even grid uses the same spacing in both directions; a row layout can use two different values.

A reliable spacing workflow

• Identify the exact crop, variety or growth habit.
• Choose the published entry matching the growing system.
• Keep plant and row spacing in their correct directions.
• Enter those values in the calculator and treat the result as geometric capacity, not a biological guarantee.
