Germination Information
Pre-treatment: None required
Establishment: The most critical factor in the collection of viable Salix seed is frequent observation of catkin development. Harvest catkins when cotton emerges from partially opened capsules. Store catkins in paper sacks to capture seed as the capsules open during drying. Seed dispersal usually only takes a few days in a room with dry air and normal working temperatures.
