• Summer honey (July and August): garden flowers, clovers: white, alsike and red, dandelion, roadside weeds (clover, dandelion, sweet clover, mustard); light amber, mixed: part of it sets quickly, part stays liquid
• Fall honey (September to November): garden flowers, fall wildflowers (goldenrod, aster); amber
• Whole season (March to November): clovers: white, alsike and red, dandelion, roadside weeds (clover, dandelion, sweet clover, mustard), garden flowers; extra light amber, likely to set over some months

Bee crops within flight range

• Grapes: about 52 acres in a typical year, nearest 1.8 mi NE, blooms early Apr – early May

From USDA's crop maps for 2021–2025; fields rotate, so a crop counts by how often it was grown. Listing a field says nothing about its owner.

The land and water around Petaluma

Things to watch

• Heavily developed. About 96% of the land within a mile is developed. Less room for forage, and more neighbors near the hives.
• Bee crops nearby that are often sprayed. Grapes (all types): insecticides used on about 58% of surveyed US acres (2021); Grapes, wine type: insecticides used on about 56% of surveyed US acres (2025); Grapes, table type: insecticides used on about 50% of surveyed US acres (2025); Grapes, raisin type: insecticides used on about 77% of surveyed US acres (2025). Figures are from USDA's Agricultural Chemical Use Survey, matched by crop type from the crop map. The survey counts any insecticide use in the crop year (not seed treatments) and doesn't say when; ask nearby growers about spray timing.

An estimate from public maps (USDA crop maps 2021–2025 averaged, LANDFIRE vegetation), not a survey of the ground. Maps can't see garden plantings, understory density, other beekeepers' hives, or this year's weather. The point is the Census Bureau's published center of Petaluma (38.2423, -122.6288); a yard a mile or two away can differ, so check your own spot. The FEMA flood map was not checked for this page.
