UK wildflower seeds have two main sowing windows: autumn (September to October) and spring (March to April). Autumn sowing is preferred because seeds receive natural cold stratification over winter, producing stronger germination rates of 70-90%. Sow at 3-5g per square metre, mixed with dry sand at a 1:4 ratio for even coverage. Native species like cornflower, ox-eye daisy, yellow rattle, and field scabious establish best in poor, unfertilised soil.
Key takeaways
- Autumn sowing (September-October) gives the highest germination rates at 70-90%
- Spring sowing (March-April) works but seeds may need 4-6 weeks of fridge stratification first
- Sow at 3-5g per square metre mixed with dry sand at a 1:4 ratio for even distribution
- Never add fertiliser because wildflowers thrive in poor soil where grasses cannot dominate
- Yellow rattle must be autumn-sown as it needs natural cold to break dormancy
- Cut the meadow once yearly in late August or September and always remove the cuttings
