Habitat for pollinators on fruit and vegetable farms

What makes a good bee habitat?

A good bee habitat may exist in the surrounding landscape of your farm. The landscape in your area will have a significant influence on the local bee population. 

Assuring there are both places to live and flowers for food helps your farm have a diverse population of bees locally to pollinate your crops. A good bee habitat includes:

  • A mix of flowering plants, including plants that bloom at different times of year
  • Areas with bare ground, leaf litter, plant stems, and dead logs that aren’t disturbed in the fall or winter.

Where Minnesota bees spend the winter

Bees are not migratory – they live in the same spot all year round. This means that we need dedicated spaces not only for bees to have their homes in the summer, but in the winter as well. Raking, removing plant debris, and fall tillage can destroy the nests where bees spend the winter.

What Minnesota bees eat

As pollinators, bees primarily rely on the nutrients they get from flowers. The key foods are nectar, which provides carbohydrates, and pollen, which provides protein, fats, and other nutrients. They also drink water from puddles, ponds, dew, and other places.

  • While our crops may bloom for only a few weeks, wild bees need food all season long. This means that farmers need to include a variety of flowering plants in the landscape from spring to fall.

  • Bees feed on a wide range of flowers, and a diverse population of bees is supported by having many types of plants that bloom at different times and have varying flower shapes.

Generally, the more diverse your local landscape is, the larger and more diverse your local bee population will be.

Where Minnesota bees live 

Minnesota’s native bees live in a few different places.

  • Some bees dig tunnels in the ground or in wood, some live in empty cavities, and some live in hollow stems.
  • Bees that live alone (solitary bees) will raise a small group of offspring (often called brood) in their nests.
  • Social bees, such as bumble bees, work together to build a colony and share tasks, including gathering food and raising young.
  • Honey bees live in hives managed and placed by beekeepers.

Cavity-nesting bees

Bees that nest in cavities look for hollowed-out areas underground, in dead trees, or in brush piles.

Ground-nesting bees

There are many species of ground-nesting bees, and each species looks for a slightly different type of ground. Some prefer bare ground, others prefer gravel, and some prefer sand. Some like areas with thin vegetation. A key thing they all need is for limited disturbance in the area where they nest. Disturbing the soil will destroy the tunnels the bees dig and the brood inside those tunnels. They also prefer the areas where they nest to have good drainage and be relatively dry.

Stem nesting bees

Stem nesting bees are solitary bees that live in hollow or pithy stems. The stems can be anywhere from 1/8 to 5/16 inches in diameter and range from 8 to 24 inches in length. These stems can be oriented in many ways–vertical, horizontal, and diagonal–all work for some species. Bees need these stems to stay intact for a while, as this is where the bees live and their young spend the winter. Therefore, the stems need to be outside for summer, fall, winter, and the first part of the following spring.

How to enhance existing bee habitat on your farm

Your farm might already be home to bees! Semi-natural areas such as fallow fields, pastures, and shelterbelts can all support bees.

How much value might these spaces have to pollinators? It will be different for every spot. Pollinators need a mix of:

  • flowering plants that bloom at different times
  • bare ground
  • protection from winter weather
  • leaves
  • stems
  • dead logs

The more of these elements a space has, the more useful it will be for local bees. When you manage these areas, the way you choose to manage them can either help or harm pollinators. 

Examples of semi-natural areas on and around farms

  • woodlots
  • along fence lines
  • roadside ditches
  • pastures
  • fields in the Crop Reserve Program

The diversity and stability of the bee population will depend on how these areas are managed. They may be managed with mowing and pesticides, which means they provide both resources for and risks to pollinators.

Tips for managing these semi-natural areas

  • Leave or enhance scrubby areas on the farm to boost pollinator resources.
  • Identify areas of low production, such as low spots or areas with poor soil, and do not farm them. By removing these unproductive areas and instead installing pollinator habitat, you may be able to boost productivity in other areas of the farm.
  • Leave trees and snags to provide bee nesting sites.
  • Be selective in weed control to manage non-native, invasive plants that compete with native species that are valuable to pollinators.
  • Mow these areas less frequently or at a higher height.

How to add bee habitat to the farm

There are many ways to add more of the habitat bees need. 

Each of these strategies can offer additional benefits, such as enhancing soil health, providing wind protection, and reducing erosion. They also come with their own costs and considerations. Each farm is different.

How to balance protecting bee habitat and managing pests

Growers using integrated pest management (IPM) techniques may see that some pollinators’ habitat requirements directly conflict with what bees need to have habitat. 

For example, ground nesting bees need undisturbed soil, but many farmers use light tillage to remove weeds, or chop crop residues at the end of the season to limit the buildup of plant disease.

It is hard for one space on our farm to do everything. While you may not be able to provide year-round, undisturbed soil where you grow pumpkins, there may be another spot on your farm where you are able to provide it.

Some Minnesota farmers set aside portions of their land for pollinator plantings that provide year-round habitat for pollinators as well as beauty.
