Dayton Apple is a Purdue selection that combines disease resistance with exceptional flavor and productivity. The trees grow to about 11 feet tall and thrive in hardiness zones 4 through 9, making them suitable for a wide range of climates. The large fruit develops brilliant red color and ripens in late September, offering a crisp, juicy texture with a perfect balance of sweet and tart notes. What makes Dayton particularly valuable is its immunity to apple scab and strong resistance to mildew, fireblight, and cedar rust, allowing gardeners to grow beautiful, flavorful apples with minimal disease management.

The fruit is striking: brilliant red, large, and loaded with crisp juiciness balanced by a sweet-tart flavor that makes it genuinely delicious straight from the tree. The tree itself is a strong grower with an upright form and sturdy branch angles, producing abundantly year after year. Best of all, this is among the very best disease-resistant apples available, immune to scab and resistant to mildew, fireblight, and cedar rust, so you can grow without the fungicide routine that plagues many apple varieties.
Dayton apples are grown fresh for eating straight from the tree, where their crisp texture and balanced sweet-tart flavor shine. The fruit's size and appearance also make it suitable for farmers market sales and home orchards where both visual appeal and flavor matter.

Plant bare-root trees in early spring or fall when dormant. Choose a location with full sun exposure and well-draining soil. Space trees 12 to 15 feet apart depending on rootstock. Dig a hole slightly larger than the root ball, backfill with amended soil, and water deeply to settle the soil around the roots.
Harvest in late September when the fruit has fully developed its brilliant red color and the apples yield slightly to gentle pressure. The fruit should separate easily from the branch with a slight twist and upward lift. Mature apples will be large and heavy; pick carefully to avoid bruising. Sample one apple a few days before your planned harvest to confirm ripeness, as sugar content peaks once the fruit transitions from firm to just-yielding.
Prune during dormancy in late winter to early spring, focusing on maintaining the natural upright form and strong branch angles that characterize this variety. Remove crossing branches, inward-growing wood, and any dead or diseased limbs. Thin the canopy to improve air circulation, which supports the tree's natural disease resistance. Train young trees to a central leader system if desired, though Dayton's sturdy branch structure requires minimal shaping.
