Encouraging Bees and Pollinators in Orchards

Why Pollinators Are the Orchard’s Quiet Workforce

A heritage orchard is more than a collection of old apple and pear trees. It is a living community, and bees, hoverflies, moths and beetles are among its most valuable members. Without them, even the most carefully pruned Ribston Pippin or Egremont Russet will carry only a fraction of its potential crop. Pollination is not simply about honeybees. Solitary mining bees, mason bees, bumblebees and many flies all play a part, often working in cooler, damper weather than honeybees will tolerate. The good news is that encouraging them is less about grand gestures and more about consistent, small-scale provision: early blossom, safe nesting places, clean water and a careful approach to spraying.

Plant for a Long, Generous Blossom Season

Pollinators emerging in late winter and early spring need food immediately. In a UK orchard, the first meaningful blossoms often come from plums, damsons and cherry plums, followed by pears, cherries and then apples. Heritage varieties can extend that window because they flower at different times. Choose a mix of early, mid and late varieties where space allows, and plant additional nectar-rich trees and shrubs along boundaries or in gaps.

• Early sources: willow, blackthorn, hawthorn, field maple, crab apple, wild cherry and gean.
• Underplanting: lungwort, comfrey, borage, crocus, hellebore, deadnettle, clover and phacelia.
• Wild strips: leave dandelions and daisies in the grass until the main apple blossom is over; they are valuable early pollen.
• Hedgerows: a mixed native hedge gives shelter, blossom and nesting cover all year.

Try to have something in flower from February to June, and again in late summer and autumn. Ivy, sedum and late-flowering herbs help bumblebee queens build up fat reserves before winter.

Nesting Sites: Think Like a Solitary Bee

Most of the UK’s bee species do not live in hives. They nest alone in holes, hollow stems, old beetle tunnels and bare ground. A tidy orchard can be short of these features, so leaving a little controlled untidiness is one of the best things you can do.

• Dead wood: keep some standing dead trees, log piles and pruned branches in sunny, sheltered spots.
• Bare ground: leave patches of south-facing soil unpaved and unmulched for mining bees.
• Stems: cut bramble, elder or raspberry canes and bundle them horizontally in a dry, sunny place.
• Bee hotels: use solid wood blocks drilled with 6–10mm holes, or hollow bamboo, and mount them at chest height facing south-east. Clean or replace them every couple of years to reduce disease.
• Shelter: bumblebees often nest in old grass tussocks, hedge bottoms or abandoned rodent burrows. Leave rough grass at the orchard edge over winter.

Water, Mud and Minerals

Bees need water, especially in hot, dry spells, and they often seek out damp mud and mineral-rich puddles. A shallow dish with pebbles or corks provides a safe landing place, but do not forget the orchard floor. A permanently damp corner, a leaky trough or a muddy patch beside a hedge can be just as valuable. Keep water clean and refreshed, and avoid deep buckets where insects can drown. If you have a pond, make sure one edge is shallow and planted, so pollinators can drink without risk.

Spraying: The Golden Rule of Bloom

Never spray insecticides, fungicides or herbicides while fruit trees are in flower. This is the single most important rule. Even products approved for organic use can harm bees, hoverflies and other pollinators if they contact open blossoms or nearby flowering plants. Spraying during bloom also risks killing the very insects that set your crop.

• Timing: if you must treat, do it before blossom or after petal fall, and never on a warm, still day when bees are flying.
• Late evening: if a spray is unavoidable, apply it at dusk when flowers are closed and pollinators have stopped foraging.
• Drift: protect hedgerows, wildflower strips and nesting sites by spraying on a calm day and using a coarse spray.
• Alternatives: encourage predators such as ladybirds, lacewings and birds; use grease bands, pheromone traps and hand removal where practical.

Make the Orchard a Year-Round Home

Encouraging pollinators is not a one-off task. It is a gentle rhythm of orchard care. In late winter, check that nest boxes and bee hotels are dry and secure. In spring, let the grass grow a little longer and hold back the mower until blossom has finished. In summer, keep water topped up and leave some flowering herbs and weeds. In autumn, resist the urge to clear every fallen leaf and dead stem; many insects overwinter in them. In winter, prune sympathetically, leaving some dead wood and hollows for nesting. Heritage orchards have always relied on this kind of give-and-take. By providing early blossom, safe nesting sites, clean water and a spray-free bloom, you will not only help bees and pollinators – you will also give your old fruit trees the best possible chance of a heavy, well-set crop.
