Crab apple 'John Downie'

Sun

Full sun gives the best flowering and fruiting; tolerates light partial shade.

Water

Water regularly while establishing; established trees usually need extra water only during prolonged dry spells.

Soil

Moist but well-drained loam, clay or sandy soil; tolerates a broad pH range but struggles in waterlogged ground.

Height

15-25 ft (4.5-7.5 m)

Spread

12-20 ft (3.5-6 m)

Flowers

Mid-spring; pink buds open to white flowers.

Foliage

Oval, toothed green leaves, often turning yellow in autumn.

Growth rate

Moderate

• Plant with the root flare at soil level and any graft union above the soil.
• Water deeply during dry weather for the first two growing seasons.
• Apply a 2-3 in (5-8 cm) mulch over the root area, keeping it clear of the trunk.
• Stake only if the root ball moves in the wind; remove supports once roots anchor the tree.
• Feed in spring only if growth is weak or soil is poor; avoid heavy nitrogen feeding.
• Remove shoots arising below the graft and collect diseased fallen leaves.

Pruning. Prune lightly in late winter while dormant, removing dead, damaged and crossing branches and retaining a balanced framework. Avoid hard pruning, which encourages upright shoots at the expense of blossom and fruit.

Pick the orange-red crab apples in early to mid-autumn when fully coloured, firm and easy to detach with a gentle twist; they are tart and best cooked into jelly or preserves. A grafted tree commonly gives its first useful crop about 3-5 years after planting, depending on its size, rootstock and growing conditions.

Late autumn

Plant while dormant where soil is workable and not waterlogged.

Late winter

Remove dead or crossing branches and check ties and stakes.

Early spring

Renew mulch and check for shoots growing from below the graft.

Spring

Avoid insecticides during flowering so bees can visit safely.

Summer

Water young trees during dry spells and inspect foliage for scab and aphids.

Autumn

Harvest ripe fruit for jelly, leaving some sound fruit for birds.

Late autumn

Collect diseased leaves and shrivelled fruit to reduce infection next year.

• Use as a small lawn specimen where spring blossom and autumn fruit can be seen from the house.
• Underplant with spring bulbs and shade-tolerant perennials for a layered seasonal display.
• Place at the edge of a kitchen garden or orchard for edible fruit and blossom visited by pollinating insects.
• Include in a mixed wildlife boundary, allowing enough space for its mature crown.

Garden styles it suits: English country, Cottage garden, Wildlife garden, Backyard orchard, Edible landscape and Traditional.

Plant it with: Snowdrops, Daffodils, Hardy geraniums, Hellebores, Lady's mantle and Hawthorn.

Wildlife: Flowers provide pollen and nectar for bees and other insects. Birds eat the fruit, although these relatively large crab apples may be taken later than smaller-fruited kinds; the branches also offer cover and nesting sites.

• Apple scab can cause dark leaf spots, fruit blemishes and early leaf fall: collect infected leaves, keep the crown open and avoid wetting foliage when watering.
• Fire blight can blacken blossom and shoots, especially in warm, humid regions: seek local guidance and cut infected wood back into healthy growth during dry weather, disinfecting tools between cuts.
• Aphids can curl young leaves: encourage natural predators and wash small colonies off with water rather than spraying flowering branches.
• Poor fruiting can follow late frost, shade or inadequate pollination: provide a sunny position and, if crops remain sparse, grow another compatible apple or crab apple flowering at the same time.

The fruit flesh is edible and is not known to be toxic to people, cats, dogs or horses, although eating much fallen fruit can cause digestive upset. Seeds, leaves and stems contain cyanogenic compounds; substantial amounts, especially chewed seeds or wilted foliage, can cause serious poisoning. Avoid crushing seeds during food preparation and keep livestock away from prunings.

• Crab apple 'Evereste' (Malus 'Evereste')

  'Evereste' has smaller, rounder orange-red fruits, often retained into winter; 'John Downie' has larger, more elongated or egg-shaped fruits.

• Crab apple 'Golden Hornet' (Malus 'Golden Hornet')

  'Golden Hornet' bears small yellow fruits in conspicuous clusters rather than the larger orange-red fruits of 'John Downie'.

Malus is the Latin name for the apple tree, while crab apple is the common name used for small-fruited apples.

Propagation. Usually propagated by budding or grafting onto an apple rootstock. Seedlings do not come true to 'John Downie', and rootstock choice affects mature size and time to cropping.
