Q.Aspens from seed
I want to plant aspen seeds, and I’ve read they start best in moist, well drained soil, on north an east facing slopes. But how deep should the seeds be planted? Soin tamed down, raked over or left loose? Direct sun, shade or mixed? Does time of year make much difference? This site is basically forest where aspens grow naturally, lots of rock, buried and loose. There are many pines and firs so acid soil.
How To Start These Seeds:
Scarification: Soak in water, let stand in water for 6 hours
Stratification: None required
Germination:Sow immediately. Surface sow and keep moist
