POLLENIZATION (Trees that are pollenized by this one): Arkansas Black, Colonnade Golden Sentinel, Colonnade Scarlet Sentinel, Fuji, Gala, Ginger Gold, Golden Russet, Golden/Yellow Delicious, Granny Smith, Hardy Cumberland, Honeycrisp, Jonagold, Jonathan, Liberty, McIntosh, Pink Lady, PREMIER Honeycrisp, Red Delicious, Royal Red Honeycrisp, Stayman Winesap, Sweet Sixteen, Urban Apple 'Blushing Delight', Urban Apple 'Golden Treat', Urban Apple 'Tangy Green', Winesap, Wolf River

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: Very resistant to apple scab, moderately resistant to fireblight and powdery mildew, susceptible to apple rust

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