Supporting bee populations through gardening begins with understanding what bees need and how they use floral resources. Bees rely on nectar and pollen for survival, growth, and colony function. A well-planned pollinator garden can provide consistent nutrition across the growing season when plant selection and layout are done intentionally.

This guide outlines the nutritional role of nectar and pollen, explains how nectar composition affects bee foraging behavior, and presents a practical method for designing a garden that supports bees from spring through fall.

Nectar and Pollen: The Nutritional Drivers of Bee Foraging

Bees visit flowers to collect two essential resources: nectar and pollen.

Nectar is the primary carbohydrate source for bees. It is a mixture of sugar and water

with trace amounts of salts that aid digestion. These carbohydrates fuel flight and day-to-day activity within the colony. Sucrose is a particularly important sugar component for bees.

Pollen supplies protein, which is critical for growth and development. Young bees consume protein during a specific window after emergence. During this early period, protein intake supports body development. After this stage, feeding behavior changes and protein consumption decreases.

Both nectar and pollen must be available in adequate amounts for colonies to function normally.

Nectar Composition and Sugar Concentration

Nectar is primarily composed of sugar and water and contains three main sugars, including glucose and sucrose. Bees show a clear preference for nectars that are rich in sucrose.

Sugar concentration strongly influences whether nectar is worth collecting:

Nectar below 30% sugar is too dilute and does not provide sufficient energy for the effort required to collect it.
Nectar above 60% sugar is too thick, making it difficult for bees to drink using their proboscis.
The optimal sugar concentration range for bees is between 30% and 60%.

When feeding bees, sugar solutions within this same range are appropriate. Concentrations as low as 35% remain effective.

Designing a Functional Pollinator Garden

A pollinator garden must be designed with scale, diversity, and local conditions in mind.

A minimum garden size of approximately 50 square feet is recommended to make the planting noticeable and attractive to foraging bees. Diversity is essential. At least two, and preferably three, different plant species should be in bloom at the same time.

Plant selection should always be region-specific. Local conditions determine whether plants will thrive and provide reliable forage. Regional plant lists are available through the USDA Natural Resource Services and local county extension offices.

Plants grouped together should have similar light, soil, and water requirements. Ongoing maintenance is necessary, including weed control and protection from wildlife such as deer, which can significantly damage pollinator plantings.

Planning Continuous Forage with a Bloom Chart

Providing consistent forage throughout the growing season requires advance planning. A bloom chart is a practical tool for this purpose.

Bloom charts typically list plant species on one axis and months or dates on the other, showing when each plant flowers. The goal is to select plants whose bloom periods overlap so that two to three species are flowering at any given time from spring through fall.

An example of layered bloom coverage includes:

Chokecherry and golden currant for early spring (April–May)
Lewis flax for extended bloom from late spring through summer (May–September)
Prairie coneflower or blanket flower to extend summer forage
Goldenrod to provide late-season nectar and pollen in August and beyond

By overlapping bloom periods, the garden becomes a reliable and continuous food source for bees across the season.

Strategic Gardening Checklist

☐ Obtain a list of recommended local pollinator plants from the USDA Natural Resource Services or your county extension office

☐ Plan a garden space of at least 50 square feet

☐ Select plants with overlapping bloom times to ensure continuous forage

☐ Ensure at least two to three species are blooming simultaneously throughout the season

☐ Choose plants with similar light, soil, and water requirements

☐ Confirm plants are suited to your soil type and water availability

☐ Implement consistent weed control to reduce competition

☐ Protect the garden from wildlife damage, such as deer browsing

Happy planting!
