What is this tool?
Works out how many plants fit a garden bed from row spacing and in-row spacing (set both equal for grid/square-foot planting), then scales up to a seed count using the germination rate printed on your seed packet plus an overseed buffer for thinning and losses. Pairs well with the plant spacing calculator for layout.
How to use it
- Enter bed length and width in feet.
- Set in-row plant spacing and row spacing in inches (equal for grids).
- Enter the packet's germination rate and a buffer, then read plants and seeds needed.
