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 4H 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 4H DECISION
Ask four 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? Is the apiary in step with local forage, weather and responsible growth? Only harvest a surplus after leaving abundant winter stores. Check queen line, mite pressure, winter survival and spring new bees; if danger is evident, diagnose and act promptly rather than waiting. Preserve the propolis envelope as support for social immunity, never as a substitute for monitoring.
COMPARE LIKE WITH LIKE
Use the same lifting point and method on each visit. Write down the equipment configuration before comparing weight: an extra box or wet roof can make a colony feel heavier without adding usable food. If hefting is unfamiliar, learn beside an experienced beekeeper rather than making a harvest or rescue decision from a single guess.
Separate two questions: how much food remains, and can the bees reach it? A heavy hive may still have stores poorly positioned for its cluster. A declining trend during a long flight gap is reason to review the food plan promptly. Avoid opening a cold brood nest simply to confirm a number; use the least disruptive check that can answer the urgent question.
HIVEVERITY: KEEP THE REASON WITH THE READ
4H sets the outcome: Happy, Healthy, Heavy, Harmony. HiveVerity is the reading and scoring system that keeps the evidence beside the decision. Use LISTEN: Look, Inspect, Sound, Touch, Evaluate, Navigate. The five audit areas are Stores, Brood Pattern, Bee Density, Temperament and Hygiene & Health, scored 1–5 only when conditions and sufficient evidence allow. Harmony adds the landscape, microclimate and forage context. Record what you could not assess; do not invent a score to fill a gap.
Keep the hive identifier, date, weather, observation, action and follow-up together. A complete score out of 25 helps organize a decision; any score of 1 or urgent sign overrides the total; it is not a health certificate or proof of a cause. These are practical teachings within Mark’s framework, not a claim that familiar beekeeping practices are exclusive inventions. The next visit should show whether the decision helped.
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.
