3H Seasonal Library
The Apiary Year Ends in the Notebook
Dormant season: learn to read survival; queen history; mite trend; harvest; interventions; weather anomalies before choosing an action.

READ THE ENVIRONMENT
Survival; queen history; mite trend; harvest; interventions; weather anomalies. These are the signals that matter before the hive tool comes out. A calendar can remind us to look, but it cannot tell us what a living colony is experiencing.
WHAT THE COLONY IS SAYING
Review each colony's full 3H record and identify which environmental cues predicted its turning points. The next year's decisions should begin with this evidence. In the 3H method, this is read through 3H: the observation must lead to a reasoned decision, not a routine manipulation. Record what you saw before acting, then record the result.
TWO YARDS, TWO EXPRESSIONS
Maintain separate yard baselines, then look for principles that travel. Your calendar should become more local and more useful every year. The lesson is not to choose one regional date. It is to recognize the same biological need through different local signals. Temperature, wind, soil moisture, bloom, elevation and surrounding land use all change the colony's timing.
THE 3H DECISION
Ask three questions. Is the colony calm enough to work without adding stress? Is brood, queen status and measured health moving in the right direction? Is there enough food for the next environmental gap? If the proposed action does not improve Happy, Healthy or Heavy, wait and observe again.
SOURCE AND LIMIT
Michael Bush's published instruction informs the cue-based practice in this lesson: https://bushfarms.com/beestiming.htm. The 3H interpretation, British Columbia field cues and final decision framework are Mark Vanderende's. The core teaching hierarchy is Mark Vanderende’s 3H method first, with Michael Bush as the primary published influence. Michael Bush has not endorsed The Foraging Bee or the 3H method. Michael Palmer and the University of Guelph provide clearly attributed supporting perspectives where relevant; their teachings do not replace or own 3H. Practical experience is not a substitute for peer-reviewed evidence, local regulations, disease diagnosis or standardized Varroa monitoring.
FIELD NOTE
At the next visit, write the cue, the colony response, the action taken—or the decision to do nothing—and what changed by the next check. That sequence turns experience into a local calendar.
