The Beekeeping Calendar: A Month-by-Month Guide

Beekeeping is a seasonal activity. Every month brings different tasks, challenges, and opportunities. Knowing what to do — and when — is the difference between thriving colonies and constant firefighting.

This calendar covers all twelve months for temperate Northern Hemisphere beekeeping (roughly USDA zones 4-7). If you live in a different climate, adjust timing by 4-8 weeks earlier (south) or later (north).

January — Planning and Preparation

What's Happening in the Hive

The colony is in its tightest winter cluster, conserving heat. The queen is not laying (in most climates). Bees are consuming honey stores slowly and maintaining a core temperature of about 95°F (35°C) through shivering muscles.

Beekeeper Tasks

Plan your season. Review last year's records. Set goals: how many colonies do you want by fall? How much honey do you hope to produce?
Order equipment. Now is the time to buy hive components, tools, and protective gear before suppliers get busy
Order bees. Packages and nucs sell out early — order by January for spring delivery
Repair equipment. Assemble frames, paint boxes, clean tools
Study. Read beekeeping books, watch webinars, attend virtual workshops
Check hives (without opening):
- Ensure entrances are clear of snow and dead bees
- Heft hives to estimate honey stores — light hives may need emergency feeding
- If a hive feels very light: place a candy board or fondant on top for emergency feed
- Brush snow off tops but don't remove it from entrances (it actually provides insulation)

Common Mistakes

Opening hives to "check on them" (you'll break the cluster and potentially kill the colony)
Forgetting to order bees in time

February — Late Winter Monitoring

What's Happening in the Hive

In many regions, the queen begins laying a small patch of brood by mid-February. The cluster is still tight but may begin expanding slightly. Maple and willow may begin providing early pollen.

Beekeeper Tasks

Continue monitoring without opening hives
Emergency feeding if stores are low — fondant, candy boards, or dry sugar on top of frames
Check for dead colonies on warm days — silence and no flight may indicate a deadout
Remove dead colonies and seal equipment to prevent robbing and moisture damage
Attend beekeeping classes and club meetings (prime education season)
Prepare feeding equipment for March
Finalize equipment orders

Common Mistakes

Feeding liquid syrup too early (it can freeze and chill the cluster)
Assuming a colony is dead just because there's no activity (wait for a warm day above 50°F)

March — The Awakening

What's Happening in the Hive

The queen is now laying in earnest. Brood area is expanding rapidly. The colony is consuming more food to support brood production — this is when starvation is most likely, even if stores looked fine in January. Early pollen sources (crocus, maple, skunk cabbage) are coming in.

Beekeeper Tasks

First full inspection on a calm day above 55°F (13°C)
- Check for the queen or eggs/larvae
- Assess food stores (critical — colonies can starve in March)
- Check brood pattern quality
- Look for signs of disease (Nosema is common in spring)
- Clean the bottom board of dead bees and debris
Begin feeding 1:1 sugar syrup if stores are low or to stimulate buildup
Install pollen substitute patties if natural pollen is scarce
First Varroa mite count of the season
Replace old comb — rotate out dark frames that are 5+ years old
Reverse hive boxes if the cluster has moved to the top box (put it on the bottom)
Remove mouse guards when temperatures consistently stay above freezing

Common Mistakes

Inspecting on a cold or windy day (chills brood, stresses bees)
Not feeding a colony that's low on stores (March starvation is common and preventable)
Missing early mite buildup

April — Swarm Season Begins

What's Happening in the Hive

The colony is building rapidly. The queen is laying at peak rate (up to 2,000 eggs per day). Drones are appearing. Population is exploding. Swarm impulse is building — this is the month to stay ahead of your bees.

Beekeeper Tasks

Inspect every 7 days — this is critical swarm season
Check for swarm cells on frame bottoms and edges
Add space proactively — add the next box when 7-8 frames are occupied
Make splits from strong colonies to prevent swarming and increase your apiary
- Take the old queen + 3-4 frames of brood and bees to a new hive
- Leave eggs and queen cells for the original colony to raise a new queen
- Or: purchase a mated queen for the split
Set up swarm traps in trees near your apiary (bait with old comb and lemongrass oil)
Continue feeding if nectar flow hasn't started
Treat for Varroa if spring counts are above threshold
Install new packages and nucs (if you ordered them)
Install drone frames for mite trapping

Common Mistakes

Not checking for swarm cells (losing a swarm = losing half your bees and your honey crop)
Not adding space fast enough
Making splits too aggressively from a colony that isn't strong enough

May — Peak Swarm Season

What's Happening in the Hive

The colony is at or near peak population. The main nectar flow is approaching or beginning in many regions. Swarms are at their peak. Queens are laying well. Drones are numerous.

Beekeeper Tasks

Continue 7-day inspections for swarm cells
Add honey supers before the main nectar flow hits
Check new splits — is the new queen laying? (should be by 3-4 weeks after splitting)
Monitor for queen issues — supersedure cells may appear on the face of the comb
Continue mite monitoring (monthly)
Add more supers as needed — during a strong flow, bees can fill a super in days
Remove feeder once natural nectar is coming in strongly
Catch swarms — check your swarm traps and respond to swarm calls

Common Mistakes

Assuming swarm season is over (it's not — keep checking)
Not having enough supers ready when the flow starts
Neglecting to check on splits and new queens

June — The Honey Flow

What's Happening in the Hive

In many regions, the main nectar flow is in full swing. Bees are collecting nectar and pollen at maximum capacity. The colony is filling honey supers rapidly. The queen continues laying but at a slightly reduced rate as resources shift to honey production.

Beekeeper Tasks

Add supers as needed — keep ahead of the bees
Inspect every 10-14 days (slightly less frequent than swarm season)
Monitor for swarming (less common now but still possible)
Check queen performance — is she maintaining a solid brood pattern?
Monthly mite count — summer monitoring is important
Ensure adequate water — bees need water to cool the hive and dilute honey for feeding brood
Keep grass trimmed around hives for ventilation and access
Consider queen rearing if you want to raise your own queens (ideal timing in many regions)

Common Mistakes

Running out of supers during the flow (you can't make bees wait)
Ignoring mite counts during the honey flow (mites don't take a break)
Not providing water near the apiary

July — Summer Management

What's Happening in the Hive

The main nectar flow may be tapering off in some regions (the "summer dearth"). Bees may become more defensive as forage becomes scarce. Colonies are large and strong. Robbing may become an issue.

Beekeeper Tasks

Continue monitoring honey stores in supers
Be alert for robbing — reduce entrances on weaker colonies
Inspect every 10-14 days
Monthly mite count — critical, as mite populations peak in late summer
Add supers if the flow continues (some regions have a late summer flow)
Plan your honey harvest — will you extract this month or next?
Prepare extraction equipment — book the club extractor if renting
Ensure ventilation — bees need airflow in hot weather
Provide water if natural sources are drying up

Common Mistakes

Triggering robbing by spilling honey or leaving supers open too long
Not monitoring mites (July-August is when populations explode)
Over-inspecting during a dearth (bees are crankier when there's no nectar)

August — Critical Month

What's Happening in the Hive

The nectar flow is ending in most regions. Mite populations are at or near their annual peak. The colony begins shifting toward raising winter bees. This is the most critical month of the beekeeping year.

Beekeeper Tasks

HARVEST HONEY from completed supers (see our How to Harvest Honey guide)
Do your most important mite count of the year — test every colony
Treat for Varroa immediately if above threshold — this is the critical window
- Formic acid is an excellent choice (penetrates brood, still warm enough)
- Apivar if you have a 6+ week window before frost
Begin fall feeding if colonies are light on stores
Assess colony strength — combine weak colonies
Reduce entrances as populations begin to decline
Remove queen excluders after harvest (so the queen can move to where the stores are)

Common Mistakes

Skipping the August mite count (this is the #1 cause of winter colony death)
Harvesting honey and forgetting to check if the bees have enough stores left
Delaying mite treatment until September (by then, winter bees may already be damaged)

September — Fall Preparation

What's Happening in the Hive

The colony is winding down. The queen is laying fewer eggs. Winter bees are being raised — these bees must live 4-6 months. Drones are being evicted. Foraging continues on fall flowers (goldenrod, aster, knotweed).

Beekeeper Tasks

Post-treatment mite count — verify your August treatment worked
Re-treat with a different product if mite levels are still above 1%
Feed 2:1 sugar syrup if colonies don't have 60-80 lbs of stores for winter
- 2:1 ratio (sugar:water by weight) is thicker, helping bees evaporate and cap it faster
Combine weak colonies using the newspaper method
- Place a sheet of newspaper between two boxes being combined
- By the time bees chew through it, they've accepted each other's scent
Reduce hive space — remove empty boxes and unused frames
Install mouse guards at entrances
Assess queen performance — if she's failing, this is your last chance to requeen before winter
Remove medication strips if treatment period is complete

Common Mistakes

Not feeding enough (colonies need significant stores — a pound a day in mild weather)
Combining colonies too late (they need time to merge and organize)
Assuming one mite treatment is always enough (verify!)

October — Final Preparations

What's Happening in the Hive

The colony is clustering on cold nights. Brood rearing is minimal or has stopped. The colony is tight and compact. Foraging is limited to warm days.

Beekeeper Tasks

Final inspection (weather permitting)
Verify winter stores — heft hives: heavy = good, light = feed immediately
Continue feeding 2:1 syrup if stores are still low (stop when too cold for bees to process it)
Switch to fondant or candy boards if temperatures are too cold for syrup
Install entrance reducers to prevent mice and reduce drafts
Add wind protection — hay bales, fencing, or natural windbreaks on the north/west sides
Ensure top ventilation — a small entrance at the top prevents moisture buildup (moisture kills more colonies than cold)
Tilt hives slightly forward so rain doesn't run into the entrance
Secure covers against wind
Clean and store extraction equipment
Take final season notes and photos

Common Mistakes

Wrapping hives too tight (trapping moisture — condensation is the real winter killer)
Stopping feeding too early (colonies need those stores)
Leaving entrance too large (invites mice and cold drafts)

November — Settling In

What's Happening in the Hive

The colony is in winter cluster mode. Brood rearing has largely stopped. Bees are tight and conserving energy. The cluster moves slowly upward through honey stores.

Beekeeper Tasks

Do not open hives (below 50°F)
Visual checks only:
- Ensure hive covers are secure
- Check entrances are clear of leaves and debris
- Look for signs of animal damage (skunks, bears, mice)
Monitor for unusual activity — bees flying on cold days may indicate a problem
Clean and store equipment — freeze frames to kill wax moth larvae before storing
Begin off-season projects — build equipment, repair tools, plan next year
Attend fall beekeeping meetings and workshops
Consider winter oxalic acid treatment during a broodless period (see our Varroa Management Guide)

Common Mistakes

Opening hives (even "just to check")
Storing equipment without freezing first (wax moth damage)

Continue visual-only monitoring
Clear snow from hive tops (but not from entrances — it provides insulation)
Ensure equipment is stored properly and protected from rodents and wax moths
Holiday gift idea: honey, beeswax candles, and lip balm from your hives
Review the year's records — what went well? What would you change?
Set goals for next year
Read beekeeping books and articles
Connect with other beekeepers — online forums, local clubs, conferences
Apply for grants or programs if you're a sideliner or commercial beekeeper
Plan next year's equipment and bee orders

Common Mistakes

Worrying too much about the bees (they've been doing this for millions of years)
Not reflecting on the season and learning from mistakes
