Add crocks and multi-purpose compost to the pot, leaving a gap of 6cm from the rim. Spread a 2cm layer of seed compost over the multi-purpose compost, and water gently.
Make a thin sowing of field cornflowers and cornflower ‘Black Ball’ over the surface. Cover with a 5mm layer of seed compost. Make a thin sowing of Eragrostis ‘Ruby Silk’ seeds over this, then cover lightly with vermiculite. It’s worth also sowing some small pots of eragrostis in pots indoors as a back-up.
Once seedlings are growing well, thin them out, leaving at least 10cm between plants. If you need to, remove patches of cornflower seedlings to make room for extra potted clumps of eragrostis. Deadhead the cornflowers regularly to extend their flowering.
