Cultivation of annual species
Grow in ordinary well drained soil in a sunny position.
Sow seeds in March/April directly into their flowering position, thinning down to required spacings.
Most poppies resent root disturbance so transplanting is not recommended.
Alternatively sow under glass in April pricking out the seedlings as soon as they are large enough to handle into trays/boxes and place in cold frame until planting out time in late May
Note; Most species self seed, dead head regularly to prevent this.
Cultivation of perennial species;
Sow seed in April in a cool greenhouse or cold frame, prick out when large enough to handle, grow on in cold frame, and plant out in suitable weather from October to March.
Divide and replant in March/April, alternatively take root cuttings and grow in a cold frame until the following March/April.
