When i was out turning my compost pile today, i was surprised when a swarm of bees emerged out of the pile itself, they may have been just as surprised that i was there as well. no, i didnt get stung and i welcome the bees. the only reason i was turning the pile is because we have had a LOT of rain the last 5 weeks and the pile was looking water logged, i thought if i moved it around a little more air etc would get into the pile etc. i had planned on using that pile this fall as i hope to install some new perrenial flower beds. My question concerns the bees, would they ovewinter there if left alone, will they die off natually etc etc etc any tips, hints or info will be greatfully accepted. i live in Nashua Nh Zone 5 typically we have very cold winters, sometimes we have a lot of snow, sometimes we dont, but its always cold.
