Why pollination is the first harvest

In a traditional orchard, the crop begins long before the first apple is picked. Apple blossoms are hermaphrodite, but most varieties are self-incompatible or only partly self-fertile, so pollen must move from a compatible variety. Bees and other insects do that work, visiting flowers for nectar and pollen and brushing grains from one bloom to the next. Good pollination means more seeds, and more seeds mean larger, better-shaped apples that hold through June drop. A tree with poor pollination may still flower beautifully, then shed most of its fruitlets. In a mixed cider orchard, where bittersweet and bittersharp varieties often flower at slightly different times, insect movement between trees is what ties the crop together.

Know your orchard's pollinators

Honeybees are the familiar workers, but they are not the whole story. Bumblebees fly in cooler, damper weather and can pollinate apple flowers when honeybees stay in the hive. Solitary bees — mining bees, mason bees and leafcutter bees — are often more efficient per visit on apple blossom. Hoverflies, beetles and even some flies also carry pollen. Do not assume one hive solves everything. A traditional orchard with old trees, hedges and rough grass supports a wider pollinating team. Encourage it by leaving bare soil for mining bees, dead wood and hollow stems for mason bees, and untidy corners for overwintering queens. If you use bee hotels, clean or replace tubes regularly to avoid disease.

Plant early nectar sources

Apple bloom is brief. Pollinators need food before and after it, especially in early spring when queens are founding nests. Plant in drifts rather than single plants, and let some areas go unmown.

• Willow and blackthorn: March to April. These are lifelines for early bumblebee queens and mining bees.
• Dandelion and lungwort: April to May. Leave the first flush of dandelions in the orchard floor; they are excellent early bee plants.
• Comfrey and clover: May to July. Deep-rooted, reliable in grass, and useful after apple bloom.
• Phacelia and borage: Quick summer bridges if you have bare ground or a vegetable patch nearby.
• Ivy: Late season. Allow it to flower on walls and old trees for queens preparing to overwinter.

Hedgerows are just as important. A mixed hedge of hazel, hawthorn, field maple and wild cherry gives shelter, nest sites and a succession of blossom.

Spraying during bloom: the line to hold

Never apply insecticides while apple, pear, plum or cherry flowers are open. That includes organic sprays such as pyrethrum, which are broad-spectrum and harmful to bees. Fungicides are less directly toxic, but some can affect bee larvae or beneficial insects, so keep them for the pre-bloom or post-petal-fall window. Wait until petals have fallen and bees have finished foraging before spraying. If scab pressure is high, choose a calm evening before pink bud or after petal fall, and always read the label. Avoid tank-mixing products. In a small orchard, cultural controls — raking up fallen leaves, pruning for airflow, choosing resistant varieties — reduce the need to spray at all.

Manage the orchard floor and hedges

Mowing is where many orchards accidentally starve their pollinators. Mow paths only, or leave alternating strips that are cut on rotation. Let dandelions, clover and selfheal flower before you top them. If you graze sheep or cattle, keep them out of the orchard during bloom so they do not browse low branches or trample nests. Leave some prunings in a quiet corner as habitat, and avoid burning every pile. Trim hedges in rotation, not all in one year, and avoid flail cutting between March and August when birds and insects are nesting. A shallow water dish with stones for landing helps bees in dry spells.

Pollination, fruit set and small-batch cider

Well-pollinated apples have more seeds, higher sugar and a better acid balance. For cider makers, that matters. A full set gives you enough fruit to blend bittersweet, bittersharp, sharp and sweet varieties consistently. Poor pollination leads to small, misshapen apples and a light crop, which can push trees into biennial bearing. If you have a small orchard, plant a reliable pollinator such as a crab apple or a known diploid variety that flowers at the same time. In a cold, wet spring, hand-pollinate the king blooms with a soft brush. Keep a notebook of bloom dates and pollinator activity. Walk the orchard at dusk, listen for the hum, and you will learn which trees and which insects are doing the real work.
