Autumn Sowing Deadlines 2015

The Autumnal combination of warm soils and plenty of moisture in the soil provides ideal conditions for seed germination of both wild flowers and grasses.

Grass seedling emergence

These grasses sown in our trials field emerged 14 days after sowing.


Sowing of wild flowers and grass seed can safely continue for as long as the favourable autumn weather lasts.  In most years and on most sites it is possible to sow with success up to the end of October.

Native wild plants are hardy,adapted to our climate and can survive most frosts. Young plants are however not so tolerant of water-logging. Late sowing is safest on free draining soils. Soils and sites that are prone to flooding are more risky - sowing in these circumstances is best postponed until spring.

October is a good month for sowing seeds into existing grass as growth and competition from the existing vegetation begins to slow as winter approaches. This also means that the all important gaps created for the seeds to grow into will last without becoming overgrown.  The good weather this autumn has however produced a lush late growth of grass which may need additional mowing or grazing through October or November.

Yellow rattle can be scattered into prepared grassland at any time in the autumn. The last sowing date for yellow rattle is Christmas.
