Germination guide
Eucalyptus polybractea seeds will usually germinate in 14-90 days, even under good conditions germination may be erratic. Sow Eucalyptus polybractea seeds on the surface of a Peaty seed sowing mix at about 22C.

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 4C or 5C 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".

Sow seed and chaff together. (Pre-chill for 4 weeks).
