How much does it have to snow before I need to clean out around the hive entrance? I have a screened bottom board, with an upper entrance and a quilt box with 6 ventilation holes. I read snow can restrict ventilation and should be cleared away. We just got 2-3 inches of snow yesterday. My hives are located off property about a half hour away. Do I have enough ventilation that I can let the snow melt off in the next day or so? Temps are going to get above freezing later today and tomorrow. How heavy does it have to snow to affect the hives even with the other ventilation measures I have taken so far? As of last week both hives are still hanging in there so I don't want to do the wrong thing! Thank you.
