Seed Calculator
Calculate how many seeds you need for your garden based on planting area, seed spacing, and germination rate. Optimize your garden planning and seed purchasing.
Step 1: Garden Area Details
Understanding Seed Calculation
The number of seeds needed depends on your garden area and planting density. Proper spacing ensures plants have enough room to grow and access to sunlight and nutrients.
Step 2: Seed Details
About Germination Rates
Germination rate is the percentage of seeds expected to sprout. Fresh seeds typically have 85-95% germination rates, while older seeds may have lower rates. Always buy from reputable sources and check expiration dates.

Seed Calculation Formula
Plants = (Area ÷ (Plant Spacing × Row Spacing)) ÷ Germination Rate
The number of seeds needed is calculated based on your garden area and planting density, adjusted for expected germination rate. Always add 10-20% extra seeds for replanting or poor germination.
