Sowing Advice

Sow  Penstemon  seeds in good quality compost or seed raising mix at any time. Lightly cover with  vermiculite or compost to their own depth. Place in a propagator or cover with a plastic lid in a warm place. We recommend germinating at 15-20 degrees C.  keep moist at all times, but do not saturate. Transplant seedlings when two sets of leaves have formed then grow on in a protected area to harden off and mature before finally planting out in the garden.
