Does anyone know if the bees retain their capacity to make propolis in the fall once the leaves have fallen?
I]m a little concerned that some of my hive bodies have shrunk a tiny bit near the middle of their long sides resulting in some small gaps between boxes, probably a result of the heavy rains we've had this fall. I'm curious as to whether the bees will be able to fill them as they would in the summer.
They are not able. They have started wintering and do not work.
Tiny gaps do not hurt colony. It gives some ventilation.
Rain water goes into the hive via gaps. If you put some plates against the wall, it will protect wall from rain.
