A colony is not a static thing. It breathes with the seasons — swelling in spring, peaking in summer, contracting in fall, and retreating into a tight, vibrating cluster when winter comes. To be a beekeeper is to understand this rhythm and work within it.
Let us walk through a year in the life of your bees.
As days lengthen and the first crocuses bloom, the colony stirs. The queen, who slowed her laying to nearly nothing in the cold months, begins to accelerate. The brood nest expands outward, ring by ring.
This is the most critical — and most dangerous — time of year. Winter stores are running low, but the spring nectar flow hasn't yet begun. Colonies can starve in March or April even as flowers start to bloom. This is why experienced beekeepers check stores carefully in early spring and feed if necessary.
As the population explodes, the hive becomes crowded. The workers begin to think about swarming — the colony's way of reproducing. They build queen cups along the frame edges. If they decide to swarm, they'll raise new queens, and the old queen will leave with about half the workers to start a new colony elsewhere.
Your job in spring: Check food stores. Watch for swarm signs. Add space if the brood nest is congested. Celebrate the buildup, but stay vigilant.
Now the colony is at peak strength — fifty, sixty, even eighty thousand bees. The foragers work from dawn to dusk, making ten or more trips per day. Nectar flows like a river into the hive. The honey supers fill with golden treasure.
This is when beekeeping feels easy. The colony is strong, the weather is warm, inspections are pleasant. But don't be lulled. Varroa mites are also building their population, hidden in the brood cells. A colony that looks healthy in June can collapse by September if mites go unchecked.
Mid-summer often brings a nectar dearth — a gap between the spring bloom and the fall flowers when little is available. Colonies can become defensive and may rob weaker hives. Watch for unusual aggression at entrances.
Your job in summer: Add supers to give the bees room for honey. Test for Varroa mites. Ensure adequate ventilation on hot days. Enjoy the abundance, but keep monitoring.
As goldenrod and aster fade, the colony's mood shifts. The queen slows her laying. The population begins to decline. The workers, sensing the coming cold, do something brutal: they drag the drones to the entrance and refuse them re-entry. The males die within hours.
This is the make-or-break season. A colony's winter survival depends almost entirely on what happens in September and October. They need enough honey stores (sixty to eighty pounds in cold climates), a healthy population of winter bees (physiologically different from summer bees, with more fat reserves), and low mite levels.
Your job in autumn: Assess stores — can you barely lift the back of the hive? If not, feed heavy syrup (two parts sugar to one part water). Treat for Varroa if counts are high. Reduce the entrance to keep mice out. Ensure the colony goes into winter strong.
The cluster forms when temperatures drop below about 57°F (14°C). The bees pack tightly together in a sphere, with the queen at the center. They don't hibernate — they shiver. By vibrating their flight muscles, they generate heat, maintaining the core of the cluster at about 93°F (34°C) even when it's freezing outside.
Bees on the outside rotate inward to warm up; bees in the center rotate out. Slowly, over the winter months, the cluster moves upward through the hive, following the honey. If they run out of honey before spring, they die — sometimes just inches from food they couldn't reach because the path was too cold to cross.
The colony consumes about a pound of honey per week in winter, more in extremely cold weather. The bees do not defecate inside the hive — they hold it, for months if necessary, until a warm day allows cleansing flights.
Your job in winter: Leave them alone. Don't open the hive when it's cold. Check occasionally for signs of life (bees flying on warm days, gentle hum when you press your ear to the side). If you're worried about stores, add a candy board or fondant — but only on a day warm enough to briefly crack the inner cover.
"The colony is not fighting winter. It is dancing with it — contracting, conserving, waiting for the sun to return."
