Cornfield Annuals will not establish very well amongst grass or other vegetation. They need to be sown on ideally weed free soil.
They should be broadcast at a rate of 2 grams per square metre. Sow from September to April. After broadcasting roll or consolidate the soil but ideally do not rake or cover the seed.
Autumn sown annual mixes should produce a mass of flowers from June onwards, with poppies, corn cockle and corn cockle most abundant. Spring sowing tends to favour corn chamomile and corn marigold.
It may be possible to re establish the mixtures after the seed has shed in the autumn by surface cultivation and rolling in the autumn.
