Pollinator Gardens for Food Production

Which food crops need pollinators?

Squash, pumpkins, cucumbers, melons, many tree fruits and berries need insects to move pollen between flowers. Others, such as tomatoes and peppers, set fruit largely on their own but can benefit from visits. Beans and peas are mostly self-pollinating. Leafy crops and root crops usually do not need pollinators, except when you grow them for seed.

If a crop is flowering but fruit is small, misshapen or falling off, poor pollination is one possible cause among several, including weather, water and disease. Your extension office can help you sort out the real cause.

A simple observation helps. Spend a few minutes beside squash or berry blossoms in the morning and watch which insects visit and how often. If you see few visitors, a pollinator planting nearby is a sound investment.

Who are your pollinators?

Honey bees are only one group. Native bees, including bumble bees, mason bees and many small solitary bees, do a large share of the work in gardens. Flies, wasps, butterflies, moths and beetles also visit flowers. Different insects prefer different flower shapes and sizes, which is why variety in a pollinator garden matters.

Most native bees nest alone in bare ground or in hollow stems and cavities, not in hives. Habitat for them means leaving some ground undisturbed and some stems standing, not just planting flowers.

Habitat extends beyond the garden. Hedgerows, meadow edges, flowering trees and unmown corners all feed and shelter pollinators, and a neighbor's untreated flowering plants may help too. Look at the whole property when you plan.

How do you plan a bloom sequence?

Pollinators need food from early spring through late fall. A garden with plenty of bloom in June and nothing in April or October leaves gaps when insects are hungry. List what is flowering at each time of year on your land, including trees, shrubs and weeds, then add plants to fill the gaps.

Ask your extension office for plants native or well adapted to your region. Native plants often suit local insects better than showy hybrids, some of which offer little pollen or nectar. Include a mix of flower shapes and colors.

Keep records of what blooms and when, and which insects visit each plant. Over a few seasons you learn which plantings do the most work and where bloom gaps remain.

• Early: flowering shrubs, trees and spring bulbs.
• Summer: a mix of perennials and herbs left to flower.
• Late: plants that bloom into fall.
• Group plants in drifts so insects find them easily.

Where should you place the pollinator planting?

Place flower areas close to food crops so insects move easily between them, and in sunny, sheltered spots where wind does not blow them off flowers. Edges, fence lines and corners of the garden work well. Pollinator beds also help beneficial insects that eat garden pests, so the benefit often reaches beyond pollination.

Do not choose invasive plants, even if they are popular with bees. Ask your extension office which species spread aggressively in your region.

Include a mix of annual and perennial plantings. Perennials come back each year and build a stable base, while annuals fill gaps quickly and can be adjusted as you learn what your insects prefer.

How do you protect pollinators from pesticides?

Insecticides can harm bees, including products labeled for garden use. Never spray open blooms, and read the label for pollinator warnings, since the label is the law. Better still, identify the pest first and try non-chemical steps such as hand picking, row cover and resistant varieties.

Treated plants from garden centers can also carry residues. Ask the seller whether plants were treated with products that affect pollinators. Drift from a neighbor's spraying is another reason to keep a buffer or hedge on the windward side.

What about nesting sites and water?

Leave a patch of bare, well-drained soil in the sun for ground-nesting bees, and leave some hollow stems and dead wood where cavity-nesters can lay eggs. Delay cutting back stems until late spring if you can. Commercial bee houses need yearly cleaning and replacement of nesting tubes to avoid disease and parasites, so ask your extension office whether they suit your situation.

A shallow dish of water with stones for landing gives insects a safe drink. Keep it clean and refilled, and keep it away from places where standing water may breed mosquitoes. Check local guidance if that is a concern. Review the planting each fall and note where bloom ran thin, so you can add plants for that stretch the next season.
