Encouraging Bees and Pollinators into the Orchard

Why Pollinators Matter in the Orchard

An orchard in full blossom is one of the great sights of the British countryside, but those clouds of pink and white are doing more than looking pretty. Every apple, pear, plum and cherry you hope to harvest depends on pollination, and while many of our top fruit varieties are partially self-fertile, they set far heavier and more shapely crops when insects move pollen between the flowers.

A healthy orchard should be buzzing by mid-May. Research from orchard studies across the country suggests that good pollination can lift fruit set significantly, and better still, well-pollinated apples tend to be larger, more evenly shaped and less prone to dropping early. Bees and other pollinators are not just a bonus for your harvest; they are part of the machinery that produces it.

The good news is that encouraging them is neither expensive nor complicated. A few thoughtful additions to the orchard and its margins can turn a quiet plot into a thriving habitat within a season or two.

Know Your Pollinators

When gardeners talk about pollinators, they usually mean honeybees, but the orchard depends on a much wider cast. Mason bees, leafcutter bees, bumblebees, hoverflies, solitary wasps and even some beetles all play a part. Each has different habits, and together they provide insurance: if cold, wet weather keeps honeybees in the hive, bumblebees will often fly anyway, working the blossom at lower temperatures.

This diversity matters because fruit blossom is short-lived. Apple varieties may flower for only ten days to a fortnight, and if that window is wet and windy, you need every willing insect you can get. Encouraging a broad community of pollinators rather than relying on one species is the surest way to secure a crop.

Plant for a Long Season of Nectar

The single most effective thing you can do is to make sure something is flowering in and around the orchard from early spring right through to autumn. Bees emerging in February need fuel long before the apples open, and pollinators preparing to overwinter need late supplies in September and October.

• Early spring: willows, blackthorn, crocus, hellebore and flowering currant.
• Blossom time: allow dandelions and clover in the grass, alongside comfrey and lungwort.
• Early summer: borage, phacelia, foxgloves and hardy geraniums.
• Late summer and autumn: lavender, marjoram, sedum, asters and ivy, which is one of the finest late nectar sources in Britain.

Underplanting the orchard with a wildflower or herbal ley is a classic approach. A mix of clover, birdsfoot trefoil, yarrow and self-heal can be sown in the alleys between trees, mown only occasionally, and left to flower between rows. It feeds pollinators, improves the soil and looks a treat. If you keep the grass short right up to the trunks, you also reduce competition and keep voles away from the bark.

Provide Nesting Sites and Shelter

Nectar feeds pollinators, but they also need somewhere to live and breed. Many of our solitary bees nest in bare ground, old beetle holes in deadwood, or hollow plant stems. Leaving a few sunny patches of bare soil, a log pile and some standing deadwood at the orchard edge costs nothing and can be surprisingly well colonised.

You can also hang a simple bee hotel: a bundle of hollow canes or drilled hardwood blocks, facing south or south-east, mounted at chest height and protected from rain. Clean or replace the tubes every couple of years to prevent disease building up. Bumblebees, meanwhile, often nest in tussocky grass or old mouse runs, so leaving a rough, undisturbed corner is a genuine help.

Shelter matters as much as food. A mixed hedgerow of hawthorn, hazel, field maple and wild cherry gives pollinators a windbreak, a corridor to travel along and another source of blossom. If you have room, a south-facing bank or a few large stones will give warmth-loving insects somewhere to bask on cool mornings.

Spray Wisely and Protect the Blossom

The most important rule is simple: never spray insecticides while fruit trees are in flower. Blossom is precisely when pollinators are working hardest, and a single careless application can wipe out the very insects you need for the crop. Always read the label, check for warnings about bees, and spray in the evening when flowers are closed and most insects have stopped flying.

Even outside blossom time, it pays to be restrained. Many orchard pests have natural predators, and a diverse, flower-rich orchard tends to keep them in check. If you must treat, choose the least persistent option, spot-treat rather than blanket-spray, and leave the hedgerows and wildflower margins untouched. Organic approaches, from grease bands to pheromone traps, are often enough in a well-balanced garden orchard.

Also resist the urge to be too tidy. Leaf litter, dead wood and rough grass are not mess; they are habitat. A little benign neglect in the right places pays dividends.

A Year of Small Habits

Pollinator-friendly orcharding is really a set of small, seasonal habits rather than a grand project. In late winter, check your bee hotel and plan your sowing. In spring, hold off the mower and let the dandelions and clover bloom. Through summer, keep water available in shallow dishes with pebbles for landing, and deadhead the flowers you want to keep going. In autumn, leave the ivy to flower and resist cutting back every stem until spring, since many solitary bees overwinter inside them.

Do these things and the rewards come quickly. Fruit set improves, the orchard feels alive on a warm May morning, and you will find yourself noticing hoverflies, mining bees and bumblebees you never knew you had. A good orchard is a working landscape, and the hum of pollinators is the sound of it doing its job.
