To avoid this sow a tiny pinch of 3-5 seeds into each module of a plug tray. Many seedlings are lost when pricking out. Sowing in February allows a full growing season for the young plants to develop unchecked but it is important to store the seed overwinter in cool, dry conditions in the bottom of a domestic refrigerator.Īs pot-grown seedlings develop the first pair of true leaves they should be pricked off into containers of a similar medium to that detailed above. Late summer and autumn sowing gives best germination in about three weeks but seedlings then need to be overwintered in a cold frame or similar. Meconopsis seed has short term viability. Meconopsis seed requires light to germinate so either surface sow and cover with a thin layer of vermiculite to anchor seeds and prevent drying out or, alternatively, top off the pot with damp perlite and sow the seed into this. Division is best done in spring at the first signs of growth.Ī suitable sowing medium for seed is two parts multipurpose peat-free compost to one part perlite, passed through a sieve.
