The flowering plants across Virginia’s fields, forests, roadsides, and backyards provide honey bees with the nutrients they require to survive and thrive — in the form of nectar and pollen. But not all forage is created equal.
🍯 Nectar – Energy for the Colony
Nectar is primarily sugar and water, but quality varies widely by plant species, time of day, and environmental conditions. Sugar concentrations can range from 5% to 92%, and honey bees use that concentration to guide their foraging decisions. Higher sugar concentrations are perceived as higher value.
The primary sugars in nectar are sucrose, glucose, and fructose, along with trace minerals, vitamins, fats, and enzymes. This is why honey is more nutritionally complex than plain sugar syrup.
Darker honeys, such as buckwheat, often contain more minerals than lighter honeys. However, mineral-rich honeys can increase f***l solids, which may create challenges during winter confinement when bees cannot take cleansing flights. This is one reason some beekeepers choose to remove fall honey and feed sugar syrup before winter.
Certain plants — including azalea and rhododendron — contain naturally occurring toxins in their nectar. While poisoning incidents are rare, it highlights the complexity of natural forage systems.
🌼 Pollen – Protein for Brood Rearing
If nectar fuels adult bees, pollen fuels brood production.
Protein levels in pollen vary dramatically, ranging from 5% to 40%. Bees require at least 20% protein pollen to properly rear brood, and pollens above 25% are considered excellent.
Examples:
• Poor protein: cypress (2.5%), blueberry (13.9%), sunflower (12.9%)
• Good to excellent: vetch (24%), white clover (25.9%), viper’s bugloss (34.9%)
But protein percentage alone is not enough. Bees require 10 essential amino acids they cannot produce themselves. Some pollens are deficient in one or more of these amino acids. For example:
• Pine pollen lacks four essential amino acids
• Dandelion lacks two
• Corn and willow lack one
Because of this, honey bees must collect pollen from a variety of plant species. The amino acids from different pollens complement one another to create a complete diet for developing larvae.
🌿 Why Forage Diversity Matters in Virginia
Colony strength is directly tied to landscape diversity. Monocultures may provide a strong nectar or pollen flow for a short window, but diverse forage supports balanced nutrition across the season.
Encouraging native plants, supporting pollinator-friendly landscapes, and understanding seasonal bloom cycles all play a role in maintaining healthy colonies.
Healthy forage supports:
• Strong brood production
• Improved immune function
• Better overwintering success
• Reduced nutritional stress
As Virginia beekeepers, understanding the biology behind forage helps us make better management decisions and advocate for pollinator-supportive environments across the Commonwealth.
