How to Use the Seed Germination Time Tool
Choose a plant from the list and press Look Up. The tool shows a typical germination window in days and the ideal soil temperature range for that seed. Use Clear to reset the form.
What the numbers mean
Germination time is a range, because seeds sprout at different speeds even in one packet.
Warmth matters most: most seeds germinate fastest at the middle of the listed temperature range.
Keep the soil evenly moist but not soaked while seeds are germinating.
Old seed, dry soil or cold temperatures can delay or prevent germination.
