'Cortland' Apple Tree - Malus domestica 'Cortland'

Discover the ultimate multi-purpose apple: the 'Cortland' apple tree. A cross between the famous 'McIntosh' and 'Ben Davis', it surpasses its parents with larger fruit and a brilliant white flesh that uniquely resists browning after being sliced. With its well-balanced sweet-tart flavour and tender texture, it is the dream apple for chefs and home gardeners alike. Robust and productive, this tree thrives in the Canadian climate, offering a bountiful harvest year after year.

Characteristics

• Foliage: Features oval, medium green leaves that form a dense, harmonious canopy. This deciduous foliage provides excellent structure to the landscape.
• Flowering / Fruit: Fragrant pinkish-white blossoms followed by large red-skinned fruit. The crisp, juicy white flesh is famous for not oxidizing (browning) when cut.
• Pollination: Not self-fertile (Group 3). Requires a pollination partner like 'McIntosh', 'Empire', or 'Honeycrisp' to set fruit.
• Light: Full sun is essential (at least 6 to 8 hours daily) to ensure optimal fruit ripening and colouration.
• Habit: Displays a rounded, slightly weeping habit at maturity, which makes fruit picking easier.
• Growth: Moderate to strong vigour; typically reaches 4 to 5 metres in height depending on rootstock.
• Soil: Prefers deep, organic-rich, and well-drained soil. Avoid heavy or compacted soils.
• Temperature: Exceptional Canadian hardiness (Zone 3), making it one of the most cold-resistant varieties for Quebec.
• Resistances: Susceptible to apple scab and powdery mildew; requires preventive care during wet spring weather.

Usage

• Types of utilization: A staple for home orchards, food forests, or as a productive ornamental specimen. Its rounded shape makes it a beautiful standalone tree.
• Decorative benefits: Provides a spectacular spring floral display and highly aesthetic red fruit contrast in late summer and fall.

Maintenance

• Watering: Maintain consistent moisture, especially during the first two years and summer dry spells to ensure steady fruit development.
• Fertilization: Apply compost every spring and use a fruit tree fertilizer high in potassium early in the season to support heavy cropping.
• Pruning: Perform annual pruning in late winter. Pay special attention to thinning the centre of the tree to allow light penetration.
• Planting: Plant in a sunny spot in a generous hole, keeping the graft union 5 cm above the soil line.
• Preventive Treatments: Apply dormant oil and lime-sulphur in early spring before bud break to eliminate overwintering pests and fungal spores.
• Winter Protection: Install a white plastic spiral tree guard every fall to protect against rodents and frost cracks.

Companion Planting

Maximize your apple tree's vigour by creating a beneficial guild at its base. Nasturtiums (Tropaeolum majus) act as a trap crop for aphids, while Chives (Allium schoenoprasum) help deter certain fungal diseases. For a natural nutrient boost, plant Comfrey (Symphytum x uplandicum), and encourage optimal pollination by adding Catmint (Nepeta x faassenii) nearby.
