Apple
Malus domestica. Family Rosaceae. Tree.
Also called Eating apple, Cooking apple, Orchard apple.
A deciduous fruit tree grown for spring blossom and apples that ripen from summer into autumn, depending on the cultivar. Rootstock controls much of its eventual size; most cultivars crop best with a compatible apple or crabapple flowering nearby.
At a glance
- Sun
- Full sun, ideally at least 6 hours daily. Choose an open site away from frost pockets.
- Water
- Water young trees deeply during dry spells for their first two or three growing seasons. Established trees need extra water during prolonged drought, especially while fruit is swelling; dwarf trees and container-grown trees dry out sooner.
- Soil
- Fertile, well-drained loam, ideally pH 6.0-7.0. Avoid waterlogged ground. Match the rootstock to your soil, available space and local climate.
- Height
- Standard trees: 20-30 ft (6-9 m); dwarf trees commonly 6-12 ft (1.8-3.7 m), depending on rootstock and training.
- Spread
- Standard trees: 15-30 ft (4.5-9 m); dwarf trees commonly 6-12 ft (1.8-3.7 m). Trained forms can be kept much narrower.
- Flowers
- Mid- to late spring; pink buds open to white or pale pink flowers. Timing varies with cultivar and climate.
- Foliage
- Oval, toothed green leaves, often softly hairy beneath; sometimes yellow in autumn.
- Growth
- Moderate; strongly influenced by rootstock, soil and pruning.
- Care needed
- High
Care
- Choose a locally suitable cultivar with the right winter-chilling requirement; low-chill cultivars are needed in mild-winter districts.
- Plant with the graft union above soil level and provide a compatible pollination partner unless reliable local pollen is available.
- Water deeply during dry weather rather than giving frequent light sprinklings.
- Keep grass away from the trunk and apply 2-3 in (5-8 cm) of organic mulch, leaving the bark clear.
- Feed in early spring only as needed for healthy growth; excessive nitrogen encourages leafy shoots at the expense of fruit.
- Support dwarf rootstocks permanently and thin crowded fruitlets to one apple per cluster, roughly 4-6 in (10-15 cm) apart.
Pruning. Prune free-standing trees in late winter while dormant, removing dead, crossing and crowded branches without stripping out fruiting wood; tip-bearing cultivars need a different approach from spur-bearers. Summer-prune established cordons and espaliers to maintain their shape, and avoid severe pruning that produces masses of upright shoots.
Through the year
- Late autumn to early spring
- Plant bare-root trees while dormant, when soil is neither frozen nor waterlogged.
- Late winter
- Prune free-standing trees and inspect stakes, ties and branch structure.
- Early spring
- Renew mulch and feed if growth or soil conditions indicate a need.
- Spring
- Watch for blossom frost and avoid insecticides while flowers are open to pollinators.
- Early summer
- Thin fruit after the natural fruitlet drop and water during dry spells.
- Late summer
- Summer-prune trained forms once shoot growth slows.
- Summer to autumn
- Harvest according to cultivar; ripe apples usually lift away with a gentle twist. Remove fallen and rotting fruit.
In the garden
- Train an espalier against a sunny fence to produce fruit without a broad canopy.
- Use dwarf trees to structure a kitchen garden, with low herbs outside the mulched trunk area.
- Plant a small orchard with compatible cultivars for blossom and a longer harvest season.
- Use a standard tree as a productive focal point in a lawn or large cottage garden.
Garden styles it suits: Backyard orchard, Edible landscape, Potager (kitchen garden), Cottage garden, Homestead and English country.
Plant it with: Chives, Thyme, Yarrow, Borage and Daffodils.
Wildlife: Flowers provide pollen and nectar for bees and other insects. Birds and mammals eat the fruit; protect developing crops with securely fitted, wildlife-safe netting where necessary.
Problems to watch for
- Apple scab: dark leaf spots and scabby fruit. Choose resistant cultivars, clear or shred fallen leaves, and prune for airflow.
- Fire blight: blackened blossoms and hooked, dying shoots. Choose resistant cultivars where it is prevalent, avoid excess nitrogen, and remove infected wood using local extension guidance.
- Codling moth: larvae tunnel into fruit. Remove damaged and fallen apples promptly, use monitoring traps, and consider fruit bags or locally recommended controls timed to egg hatch.
- Poor fruit set: often caused by blossom frost, unsuitable winter chilling or lack of compatible pollen. Choose locally proven cultivars, avoid frost pockets and check pollination compatibility.
Safety
Ripe flesh is not known to be toxic to people, cats, dogs or horses. Seeds, leaves and stems contain cyanogenic compounds; substantial ingestion, especially of chewed seeds or wilted foliage, can cause serious poisoning. Accidentally swallowing a few intact seeds is unlikely to harm a person, but keep prunings away from livestock and do not let pets chew cores. Whole apples can choke horses, and large quantities of fruit can cause digestive illness.
Easily confused with
Crabapple (Malus spp.)
Usually bears much smaller fruit, commonly under 2 in (5 cm) across. Crabapples and domestic apples overlap, so fruit size alone is not a definitive distinction.
Common pear (Pyrus communis)
Leaves are generally glossier and less hairy, flowers usually have dark anthers, and most cultivars produce fruit narrowed towards the stalk.
Quince (Cydonia oblonga)
Has leaves with untoothed margins, solitary flowers and large yellow fruit that is often fuzzy and strongly fragrant.
The name
Malus is the Latin name for apple, and domestica means cultivated or belonging to the household.
Propagation. Named cultivars are propagated by grafting or budding onto a suitable rootstock. Seedlings do not come true to type, may take many years to fruit, and have unpredictable fruit quality and size.
