Seeds & planting
Work out why seeds have not germinated
Check the date and the variety’s expected germination period; some seeds are naturally slow.
When to do it
After the packet’s expected germination period has passed.
What you need
- Packet and sowing record
- A few spare seeds
How to do it
- Check the date and the variety’s expected germination period; some seeds are naturally slow.
- Review temperature, light, sowing depth and moisture. Cold wet mix, a dry seed layer and overly deep sowing need different corrections.
- Inspect a small sample, leaving the rest undisturbed. Rotten seed suggests excess wetness; missing seed may indicate animals or displacement.
- Test spare seed separately or resow a small batch with the identified problem corrected, only if the planting window still allows.
What success looks like
- The new batch tests a specific explanation.
Watch out for
- Watering more without checking moisture.
- Repeatedly digging up every germinating seed.
