Pennsylvania Beekeeping Calendar
A month-by-month task guide for beekeeping in Pennsylvania, based on the Upper Midwest & Northeast climate. Pennsylvania's main bloom season runs april through october, so adjust these dates a week or two to match your local flow.
Upper Midwest & Northeast at a glance: A classic four-season beekeeping climate: a defined spring build-up, a June–July main flow, an August harvest, a fall goldenrod flow, and a long, cold winter that demands heavy stores and good moisture control.
Winter
Dec – FebLong, cold winter — the cluster stays sealed in.
- •Do not open the hive; heft from behind to judge weight.
- •Add fondant or dry sugar on top if the colony feels light.
- •Keep upper ventilation open to vent moisture; clear the entrance of snow.
Early Spring
Mar – AprBuild-up begins with maple and early bloom.
- •First full inspection on a warm day; confirm a laying queen.
- •Take your first varroa count and treat if above threshold.
- •Feed 1:1 syrup and pollen if stores are low or spring is cold.
Spring Flow & Swarm Season
May – JunDandelion, fruit, and locust bloom with heavy swarm pressure.
- •Reverse boxes, add space, and super before the flow.
- •Inspect weekly for swarm cells; split or manage crowded colonies.
- •Requeen or make nucs while drones are abundant.
Main Flow
Jun – JulPeak nectar flow — clover, basswood, and wildflower.
- •Keep supers ahead of the bees so they never run out of room.
- •Ventilate for summer heat.
- •Monitor mites; do not let them build under the honey.
Harvest & Mite Window
AugPull the crop, then protect the winter bees.
- •Remove and extract capped honey.
- •Do your critical late-season mite treatment as supers come off — this protects the winter bees.
- •Assess stores and start planning fall feeding.
Fall
Sep – OctGoldenrod flow, then winter prep.
- •Let bees pack the goldenrod and aster flow for winter.
- •Feed 2:1 syrup to reach winter weight (roughly 60–90 lb of stores).
- •Install entrance reducers, mouse guards, and upper ventilation; combine weak colonies.
Timing is approximate. Local weather, elevation, and forage can shift these dates by weeks — your own hive records are the best calendar of all.
