In this lesson: the realistic shape of your first year (building, not harvesting), the month-by-month NorCal arc, and the common mistakes that cost first-year colonies.
By the end of this lesson you can: describe what a colony does in each season of year one, state the feeding ratios and when to use them, and name the mistakes most likely to cost you a colony.
We'll be honest: colony loss is common. The 2025-26 US Beekeeping Survey (Auburn University and Apiary Inspectors of America, preliminary) estimated 30.3% winter and 39.9% annual colony losses; backyard beekeepers lost 54.8% over the year. That tells you what you're up against. This isn't meant to discourage you. The difference between colonies that make it and those that don't is mostly knowledge and timing, which is what this course is for.
The First-Year Reality
Your first year is about building, not harvesting. A new colony, from a package or a nuc, has to accept its home, build comb on empty frames, raise enough bees to be self-sustaining, store food for winter, and survive mites, disease, and environmental stress.
Plan to harvest nothing in year one. A small harvest is a bonus; none is normal.
Month-by-Month Preview (NorCal)
This is the short version. The Year One Timeline lesson in Module 2 goes deeper, and Module 8 covers every month.
| When | What's happening | Your job |
|---|---|---|
| March to April | Bees arrive (packages first, nucs a few weeks later). Fruit and early wildflower bloom. | Install, feed 1:1 syrup while they draw comb, first inspection at day 5 to 7, then roughly every two weeks. |
| May to June | Population explodes. The spring flow is on. Swarm season. | Learn to read frames, add a second box when the first is about 80% drawn, watch for queen cells, plan your first mite sample. |
| July to August | Nectar dries up in the valley. Bees get defensive; robbing risk. | Reduce the entrance, sample for mites (alcohol wash), and treat if you're over threshold. |
| September to October | Winter bees are being raised. Brood slows. | Confirm treatment worked, check stores, feed 2:1 syrup if light, add a mouse guard. |
| November to February | Cluster forms. Little or no brood. | Hands off. Heft the hive to gauge stores. Consider an oxalic acid treatment while broodless, following the label. |
What Success Looks Like at 12 Months
By next spring you'll have a colony that survived winter, a laying queen, bees building up for the new season, and the confidence to know what you're looking at. That's success. Not honey. Survival and knowledge.
The Common First-Year Mistakes
- Opening the hive too often. Weekly inspections stress bees and set back comb-building. Every two weeks is plenty in the active season; in winter, leave them alone.
- Not monitoring mites. "I'll do it naturally" with no testing is a common path to a dead colony. Learn the alcohol wash, sample regularly, and treat when a sample crosses the seasonal threshold. The Honey Bee Health Coalition's current guide sets that threshold at about 1 mite per 100 bees in spring and dormant periods and 2 per 100 in summer and fall. Module 3 covers this in full.
- Missing the late-summer window. Winter bees raised while mites are high can be short-lived and carry viruses. A colony can look strong in September and be gone by midwinter.
- Harvesting honey the bees need. Year one, take none.
- Not feeding when needed. New colonies on bare foundation usually need 1:1 syrup in spring, and may need 2:1 in fall if stores are light. Stop feeding once a real nectar flow is on, or they'll backfill the brood nest with syrup.
- Wrong feed ratios or feed sources. Use 1:1 (sugar to water by weight) in spring to stimulate comb-building and 2:1 in fall to pack away stores. Never feed honey from another hive or an unknown source; it can carry American foulbrood spores.
- Waiting too long to ask for help. A 10-minute call with a local mentor at the hive beats a dead colony.
A note on winter stores: Plan on at least 40–60 lb of capped honey for a full-size colony on the valley floor or coast (mild-winter extension guidance: Alabama Extension at least 40 lb, Mississippi State 60–65 lb). Colder foothill and Sierra sites need more, toward Cornell's 80 lb. Heft to check and ask your club. Mild winters help, but brood rearing can continue and burn through stores.
The Right Mindset
Think of year one as bee school, for you and for them. You're learning to stay calm around tens of thousands of stinging insects, read what's happening inside the hive, and react to problems. The bees are learning to build, grow, and store. Neither of you will be perfect.
What This Course Will Give You
Over the next seven modules you'll learn how to install and inspect your first hive, keep it healthy, manage queens, swarms, and splits, harvest when the time comes, and know what to do every month in NorCal.
In the next lesson we cover safety and stings, then Module 2 gets you your bees.
