Heavy or Light? The Pre-Spring Stores Check
Late winter: learn to read hive heft; cluster position; forecasted cold; remaining stores before choosing an action.

READ THE ENVIRONMENT
Hive heft; cluster position; forecasted cold; remaining stores. 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
Lift from the back and compare hives in the same yard. A cluster high under the lid with little weight behind it deserves attention; a heavy box does not need stimulation. In the 3H method, this is read through Heavy: 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
Interior colonies can face a long gap before reliable pollen. Coastal colonies may brood earlier and consume stores quickly during rainy weeks. 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://www.bushfarms.com/beesfeeding.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.
