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

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 Isleton (38.1613, -121.605); a yard a mile or two away can differ, so check your own spot. The FEMA flood map was not checked for this page.
