Unlike the seeds of midsummer, these spend the winter under the snow and germinate in early spring. Seeds of all species can be stored if collected at the time they are dispersed and frozen within several days. Keep them frozen until planting time and then spread them on wet soil or paper towels. Within on one or two days, you will have many little trees and shrubs which can be used for a variety of landscaping purposes. Green plants get their energy from the sun.
Plant leaves draw carbon dioxide from air and combine it with water to make carbohydrates.
Research and discuss why water is important for willows. PLT Approximately three weeks before beginning the activity, place about 50 willow seeds in a clear jar on a layer of damp paper towels and put the jar near a window. Monitor the seeds daily, and keep the paper towels moist. Discuss with students what seeds need to sprout and develop. Seedlings will be ready for experimentation when they have developed leaves and roots.
