Propagation of Mountain Ash:

Seed - surface sow February/March in a sunny position in a greenhouse. Species that come from high altitudes appreciate 6 - 8 weeks cold stratification at 2C. Pot up the seedlings into individual pots as soon as the second set of seed leaves has developed, if left longer than this they might not move well.
