Peter (Edwards) Have you ever touched the leaf buds of the "Horse Chestnut"just as they are bursting? - they are resinous. Poplar buds exhibit the same sticky touch on the protective covering as the start to be pushed apart from growth that takes place when the leaves grow in spring. Propolis "collection" and use in the fall - bees are seen to seal as many cracks etc. in their colony container - are they just using propolis that has been stored?
