SCIENTIFIC NAME: Malus domestica 'Jonagold'

COMMON NAME: Jonagold Apple

GARDEN SIZE: 12-15 ft. tall and wide

USDA ZONE: 4-8

EXPOSURE: Full Sun

WATER & SOIL: Loamy & well drained soil

HABIT (FORM): Semi-dwarf

FOLIAGE: Deciduous; Green

BLOOM TIME: Late-midseason - Flowering Group 4

HARVEST TIME: Late-midseason, ripens mid-October

FRUIT: Large apples with a balanced, sweet-tart flavor and gold skin that blushes red as the apple matures. Jonagold's Golden Delicious parentage lends it the trait of storing well, while its Jonathan ancestry enhances the apple's flavor.

POLLENIZATION: Not self-fertile and does not pollenize other apple trees. Needs another compatible tree nearby to produce fruit. Due to their close relation, Jonathan and Golden Delicious apple trees do not pollenize Jonagold.

POLLENIZATION (Trees that pollenize this one): Colonnade Golden Sentinel, CrimsonCrisp, Fuji, Gala, Ginger Gold, Granny Smith, Hardy Cumberland, Honeycrisp, Pink Lady, Premier Honeycrisp, Red Delicious, Royal Red Honeycrisp, Sweet Sixteen, Urban Apple 'Blushing Delight', Urban Apple 'Golden Treat', Urban Apple 'Tangy Green', Wolf River

POLLENIZATION (Trees that are pollenized by this one): None - this tree has sterile pollen and does not pollenize other apple trees.

CARE: Prune while the tree is dormant. Remove water sprouts in June or July. Options for controlling pests, bacterial infections, and fungal disease include dormant oils applied early in the season before blooming, scented insect traps, and copper-based fungicides. DO NOT apply insecticides during blooming. This risks harming bees, which are crucial for pollination and fruit production. If necessary, fireblight can be treated with a streptomycin antibiotic spray during blooming. Apple trees need about an inch of water every 7-10 days, though young trees need a little more during their first growing season as they establish roots. If not enough rain has fallen, give the tree extra water by running a hose at a trickle around the base of the tree until the ground is fully soaked (but not for so long that there is standing water). Waterlogged roots can harm apple trees, so don't overdo it!

DISEASE RESISTANCE: Susceptible to cedar apple rust, fireblight, powdery mildew, and scab. Despite its susceptibility, Jonagold is a vigorous tree and seems to survive and recover well.

USES: Eating fresh, cooking, juice and cider

TOXICITY: Stems, leaves, and seeds contain cyanide and are therefore toxic to dogs, cats, horses, and humans. The fruit is non-toxic.
