Spring Management: Supplemental Feeding
After dropping way down over the winter, the bee population in a hive starts to build up again quickly in the spring as days grow longer and warmer. The hive entity, of course, wants to be at full strength when the major nectar flows come on in May-July.
March is a critical month to keep a close watch on your hive to ensure that the bees don't starve- I'm told that hives may eat as much in a month in the early spring as they did over the 3-4 winter months combined- lots of new mouths to feed!
People use all kinds of sugar sources to feed their bees: sugar syrup, candy canes, "fondant." I use a sugar syrup solution (1:1 sugar:water) in a 'Boardman Feeder' pictured here. While my initial inclination was to make the syrup using honey (as in this picture), I have since learned that simply using white, granulated sugar is easier on the bees because it more closely mimics a nectar that they would naturally prefer.
Making honey, after all, is the bee's strategy to preserve nectar- not a method of converting it into a preferred form of carbohydrates. It's also worth noting (for those of us who try to avoid processed sugar) that the bees are not converting your sugar syrup into honey that you're going to eat- it's just keeping them going during the nectar dearth in the early spring.

Emerging Worker Bee
Brood Pattern
The queen in my hive is approximately two years old- a time when the queen's productivity will often begin to drop off. I spoke with a friend yesterday who's queen had started laying only drones; another sign of an aging queen is poor brood pattern (patchy).
My plan was to replace the queen this year by letting the workers raise a new one from a 'queen cup' during swarm season, but I was pleasantly surprised by the solid brood pattern I saw on a number of frames today. I'll need to check with Chip about whether to let her stay in charge for another season!
This photo shows a very solid brood pattern on a frame in box 2- notice the larvae in the uncapped cells. The arc pattern of the brood (w/ some honey cells at upper right) is typical.
Spring Management: Reversing Hive Boxes
I overwintered my hive with three western supers this year; many people will use two deep supers but I just use westerns in my backyard hive so I go with three to provide adequate space and honey stores for the colony (westerns are shallower than deeps, so the bees have less space on the frames- hence the extra box).
During my last hive check, it was apparent that the bees had all moved up into the top two boxes after eating all the honey out of 'Box 1,' the bottom box. Bees have a natural tendency to move upwards, and the queen is apparently reluctant to move back down into lower boxes even if the upper boxes are getting crowded.
So, today I went in and moved Box 1 up to the top position; essentially rotating the boxes (Box 1 moves to Box 3 position, 3 moves to 2, 2 moves to 1). The queen now has a full box of frames with fully drawn comb to start laying in.
I also added a boardman feeder with a dose of Nosevit- more on that later.

Moldy Pollen
On my first hive check of the season (February 19th), I noticed a couple of pollen cells that had mold on them. There were maybe 35 total cells with the white mold on them, ALL of them out the outer side of the outmost frames in the honey/pollen frames that fed my bees through the winter.
Chip says, no problem- it happens with our wet winters here. The only concern would be chalkbrood, which begins on brood cells near the center of a super, which these were not.
Drone, up close
On sunny spring afternoons like yesterday's, I love pulling up a chair next to my backyard hive and watching the field force come home, bringing in the first pollen and nectar of the season. I'm told that experienced beekeepers are quite capable of discerning the source of pollen by it's color (in the context of the season). I'm not quite there yet...
Yesterday, there was a drone hanging out on the landing board- I grabbed some photos of the drone next to worker bees for a comparison of size, color, body shape etc. The drone is the big guy with the big dark eyes- almost 1/3rd larger than the workers, to my eye.
Note the worker on the bottom left, bringing in some golden-orange pollen in her 'pollen basket.'
