Iain asked, One final request for info, how long is it advisable before pricking out the seedlings into individual 'pots'. The standard size >used here is what we call a 9 cm pot, i.e. square and 9 cms = very roughly >4 inches, tall, wide and deep.My inclination would >be to prick them out say in August to allow time for a root system to >develop ahead of winter to avoid frost heave, or is that >too late / too soon? For most western American bulbs, it is best to leave them in the seed pots for two years and then to move the young bulbs into larger pots while they are dormant in July or August. Fertilize the seedlings at half strength and do not dry young seedlings out severely while they are dormant. Do not let the pots freeze. Jane McGary
