Seeds for sowing guide
Estimate seeds from target plants and your success rates.
Measure and prepare
- Check the units shown for each input. Measure the actual inside dimensions or net area required by this tool.
- Use manufacturer coverage, dose, pack size or your measured flow where applicable. Do not treat example inputs as product recommendations.
- Check the assumptions below, update the starting values and review whole-unit purchase rounding where applicable.
Method and limits
Target plants ÷ (germination percentage × establishment percentage), with percentages expressed as fractions. Round up to whole seeds. These assumptions do not guarantee a plant count.
Worked example
With the editable starting values: 20 seeds. Target: 14 target plants · germination 80 % · establishment 90 %. Estimate, not a guarantee.
- Target established plants: 14
- Expected germination (%): 80
- Expected establishment (%): 90
