I have a booming 3 deep hive going and the cherry blossom trees are now in the process of blooming. Cherry blossom honey is very rare here and will fetch a high price. I'm really trying to get the bees to harvest as much as they can. I've been reading about cut down splits and feel this is the answer for a good honey crop as we'll as a preventing swarming. This hive already has 10 or 12 queen cells in progress. They are not yet capped but they will be in the next couple of days. My question is this. Should I go ahead and do the cut down split? The temps are around mid 60's in the day and mid to low 40's at night. Is this too cool for a split?
