- Species and varieties: Green apple seeds belong to the species Malus domestica. Popular heirloom varieties of green apples include 'Granny Smith', 'Newtown Pippin', and 'Antonovka'. These varieties are known for their tart flavor and crisp texture.
- Hybrid or heirloom: These seeds are heirloom varieties, meaning they are open-pollinated and have been passed down through generations without genetic modification. Heirloom seeds are valued for their historical significance, genetic diversity, and unique flavors.
- Pruning and training: Pruning is essential for green apple trees to maintain their shape, remove dead or diseased wood, and promote healthy growth. Prune during the dormant season, typically in late winter. Training young trees to a central leader or open center form can improve air circulation and sunlight penetration.
- Fertilization needs: Green apple trees benefit from regular fertilization. Apply a balanced fertilizer in early spring before new growth begins. Additional applications of nitrogen may be needed during the growing season. Organic options such as compost or well-rotted manure can also be used to enrich the soil.
- Hardiness zones: Green apple trees are suitable for USDA hardiness zones 4 through 8. They can tolerate cold winters and require a certain number of chill hours to produce fruit.
- Climate requirements: Green apple trees thrive in temperate climates with cold winters and warm summers. They require full sun exposure and well-drained soil. Adequate rainfall or irrigation is necessary, especially during the growing season.
