As with all creatures, good nutrition is very important to a colony of bees. Many beekeepers only look at the amount of liquid stores a colony has, but pollen is equally important, yet often ignored. A lack of liquid stores can lead to starvation in both summer and winter, but a shortage of pollen can have a serious effect for some time, as poorly nourished larvae can result in poorly performing or unhealthy adults.
As a beekeeper, it is important to “read” a colony, because it is telling you something all the time. On each inspection, get into the habit of looking into a few cells where there are freshly hatched larvae, around 4-5 days from egg laying. If there is plenty of food coming in, the larvae will be in a big puddle of brood food, but if there is little food coming in, the bottoms of the cells will be almost dry. I wish this sort of observation was taught more by teachers.
