Squash Hill Spacing Calculator

About this calculator

Squash is traditionally planted in hills — small mounded clusters of several seeds spaced apart along a row, rather than a continuous line, since sprawling vines need room. The number of hills that fit is simply row length ÷ hill spacing (rounded down), and total seed need is that hill count multiplied by the seeds planted per hill (growers typically over-sow 3-4 seeds per hill and thin to the strongest 1-2 plants).

This calculator takes your row length, chosen hill spacing, and seeds per hill and returns the number of hills that fit and the total seeds required. Home gardeners and small-scale market growers use it when laying out a vegetable bed for squash, pumpkins, melons, or cucumbers — crops that share the same hill-planting convention — to buy the right amount of seed and space vines so they have room to spread.
