Every important hive decision in Cache Valley keys off the bloom calendar, not the wall calendar. Add supers because the clover is opening, not because it's the first of June. Treat for Varroa because the dearth is on, not because it's mid-July. The poster above is a one-glance summary; this post walks through how to actually use it.
The Three Windows That Drive Every Decision
The poster breaks the season into three flow windows. If you only remember three things about Cache Valley beekeeping, remember these.
Window 1 — June Clover Flow
White clover and sweet clover open across the valley floor in late May and explode through June. Alfalfa starts blooming at the end of the month. A strong colony can pack on 5–10 lbs of nectar per day during the peak. Have your supers stacked and ready by the first week of June. If you wait until the flow is obvious, you've already lost a week.
If you don't have supers yet, our Established Beekeeper kit includes mediums, a queen excluder, and an uncapping knife — the kit is sized to actually capture the June flow rather than discover it later.
Window 2 — Late-July Dearth
When clover finishes and the fall flowers haven't started, there's a lean stretch — usually two to four weeks in late July. Robbing spikes, bees get defensive, and weak colonies get pillaged. This is also the critical Varroa treatment window. Capped brood is at its yearly low, so treatment efficacy is at its yearly high, and the winter bees being raised in August need to emerge from mite-free cells.
Full treatment timing and product picks are in the Cache Valley Varroa treatment guide. If you only do one mite treatment a year, do this one.
Window 3 — August–September Fall Flow
Goldenrod, rabbitbrush, and aster give the colony a second wind through the end of the season. This nectar is for the bees, not for you. Dark fall honey is what keeps a colony alive through February in Zone 6b. Resist the urge to harvest unless the colony already has 60+ lbs of stores going into October — and confirm that by hefting from behind, not by eyeballing it.
How to Use the Poster
The poster is intentionally short on hive actions — it's a forage reference. Pair it with these three:
- Print it for the bee shed. A glance at the timeline tells you whether you're in flow, dearth, or fall build-up — useful when you're standing in front of an open hive trying to decide whether to feed.
- Cross-reference the full bloom calendar. The reference page has the same months, plus dearth-risk ratings, hive actions, and links to the gear that matches each season.
- Read it alongside the forage guide. The forage guide goes deeper on peak flow timing, what to plant near a hive, and how each bloom shapes the flavor of the honey.
A Note on Micro-climates
"Cache Valley" covers a wide range of elevations and exposures. The valley floor around Logan and Smithfield typically blooms a week or two ahead of the bench, and Preston (slightly cooler) trails Logan by a few days. South-facing slopes around Wellsville start dandelions earlier than the rest of the valley. The poster gives you the average — your bees will tell you the local truth.
