When to sow: Sept-Oct/April
California poppy tips: Poppies do not like to have their roots disturbed so its best to sow them direct.
Seeds can be broadcast onto well-prepared ground from early April and raked in gently to cover the seeds. Alternatively they can be sown in drills 20cm apart and thinned. This way it is possible to use a hoe to weed in between the rows.
They should be placed in full sun.
