Picea pungens Glauca Majestica seeds will usually germinate in 30-60 days, even under good conditions germination may be erratic. Normally will only germinate with light so surface sow. Sow Picea pungens Glauca Majestica seeds on the surface of a sandy, calcareous seed sowing mix at about 21°C.
Stratification (cold treatment or vernalization) Some seeds need to be overwintered before they will germinate. Some seeds need just a couple of weeks, others 3 months. Seeds can be stratified in dampened peat or sand, in a plastic box or bag at 4°C or 5°C in a refrigerator. The seeds should not be frozen or in a wet medium. Very small seeds can be sown on the surface of their growing medium, in pots sealed in plastic bags, and kept in the 'fridge. Many vernalized seeds need light to germinate when they are sown in the "Spring".
Pre-chilling has been found to be unnecessary. Picea pungens seeds germinate best if kept warm and in contact with (pressed into, but not covered by) humid, calcareous soil. Mycorrhizae are usually found on seedlings.
