Spinach Seed Germination: What to Expect
Spinach seeds typically germinate within 5 to 14 days. However, several factors can influence this timeframe.
- Seed Quality: Fresh seeds have higher germination rates.
- Soil Temperature: Optimal temperatures are between 50°F and 70°F (10°C - 21°C).
- Moisture: Consistent moisture is crucial, but avoid overwatering.
- Light: Spinach seeds require darkness to germinate.
- Seed Depth: Sow seeds ¼ to ½ inch (0.6 - 1.2 cm) deep.
För att förbättra grobarheten:
- Soak seeds in water for 24 hours before planting.
- Use a seed starting mix for optimal drainage and aeration.
- Maintain consistent soil moisture with a spray bottle.
- Consider starting seeds indoors 3-4 weeks before the last frost.
Germination Timelines Under Varying Conditions
| Skick | Temperatur (°F) | Förväntad groningstid (dagar) | Groningshastighet (%) - Ungefärlig |
|---|---|---|---|
| Optimalt | 60-70 | 5-7 | 85-95 |
| Cool | 50-60 | 7-10 | 75-85 |
| Kall | 40-50 | 10-14+ | 50-70 |
| Varmt | 70-80 | 7-10 (potentiellt reducerat) | 60-75 |
Germination rate is an estimate and can vary based on seed quality and other factors.
