ABOUT
The 'Delcorf' apple tree, known as Malus domestica Delbarestivale, is a cultivar that produces red apples. The tree exhibits a strong central leader and a well-branched structure, creating a characteristic silhouette of an apple tree. Throughout the seasons, the tree's appearance changes dramatically. In spring, it bursts into life with a show of delicate white to pale pink blossoms, which attract pollinators and promise future fruit. The leaves are lush and green, ovate in shape with a slightly serrated edge, providing a dense backdrop to the flowers. As the season progresses and flowers are pollinated, small green fruits begin to form, gradually swelling over the summer months. By late summer or early fall, those fruits mature into the striking red apples that give this tree its renown. These apples have a glossy skin that ranges from a light pinkish-red blush to a deeper red hue, depending on sun exposure and other growing conditions. The flesh of the 'Delcorf' apple is typically crisp and juicy with a balanced, sweet-tart flavor, making it desirable for fresh eating. In the fall, the tree's leaves transform into warm hues of yellow and orange, presenting a beautiful contrast against the bright red apples. This seasonal change adds ornamental value to the tree before it sheds its leaves for winter dormancy. During the winter months, the bare branches reveal a sturdy, woody structure, which stands resilient until spring returns.

ToxicityTo humans
The plant commonly known as the apple tree is not toxic to humans when it comes to the fruit (apples) they produce. Apples are safe and commonly consumed worldwide. However, other parts of the apple tree, including leaves, stems, and especially the seeds, can contain traces of a compound called amygdalin, which can release cyanide when metabolized. The ingestion of a large quantity of apple seeds may lead to symptoms of cyanide poisoning such as headache, confusion, anxiety, vomiting, and potentially more severe symptoms such as respiratory failure and cardiac arrest. Accidental consumption of small amounts typically does not lead to toxicity due to the body's capacity to detoxify cyanide in small doses, and because apple seeds have a protective coating that may prevent the release of cyanide when intact.
To pets
Apple trees are known to be toxic to pets, but the level of toxicity varies depending on the part of the plant consumed. The fruit flesh of apples is generally safe for pets like dogs and cats in moderation. However, the core and seeds of apples can be harmful. Apple seeds contain amygdalin, a compound that can release cyanide when digested. Symptoms of cyanide poisoning in pets may include dilated pupils, difficulty breathing, panting, shock, and in severe cases, coma or death. It is important to prevent pets from having access to the seeds, and to always remove the core before sharing a slice of apple with your pet. Small amounts of seeds are unlikely to cause poisoning, especially if they are not chewed, but it's best to avoid the risk entirely.

WaterApple trees, including the 'Delcorf' variety, should be watered during dry spells to promote healthy growth and fruit development. Young trees typically need about 1 to 1.5 gallons of water once a week, whereas mature trees may require 2 to 4 gallons weekly, especially during the peak of summer. The best method is to slowly water the base of the tree, allowing the water to penetrate deeply into the soil, reaching the root system. It's important to avoid overwatering, as this can lead to root rot. During the winter months, watering is often unnecessary unless there is an extended period of drought.
LightThe 'Delcorf' apple tree thrives in full sunlight, requiring at least six hours of direct sunlight daily. The best spot for planting is an open area with clear exposure to the sun throughout the day. Avoiding shaded areas is crucial for the development of healthy fruits and to prevent disease.
TemperatureApple trees, such as the 'Delcorf', are hardy and can withstand a range of temperatures. They can typically tolerate winter lows down to -20°F, while the ideal growing temperatures are between 60°F and 75°F. However, temperatures consistently above 90°F can be detrimental to the tree and its fruit production.
PruningPruning the 'Delcorf' apple tree is vital for maintaining tree health, encouraging fruit production, and enabling sunlight to reach the inner canopy. Prune during the dormant season, in late winter or early spring, before active growth starts. Remove dead, diseased, or crossing branches and thin out the canopy to improve air circulation. Annual pruning is recommended, but be careful not to remove more than a third of the tree's total growth in a single year.
CleaningAs needed
SoilApple trees like Malus domestica 'Delcorf' thrive best in well-draining loamy soil with a pH range of 6.0 to 7.0. Amend the soil with compost and balanced fertilizer to provide a nutrient-rich environment for robust growth.
RepottingApple trees such as the Malus domestica 'Delcorf' are typically not repotted as they are commonly grown outdoors. In a nursery setting, they might be transplanted every 1-2 years until they are planted in their permanent location.
Humidity & MistingMalus domestica 'Delcorf', or apple trees, prefer moderate ambient humidity but are adaptable to a wide range, without specific humidity requirements, making them versatile in various climates.
Suitable locationsIndoor
Growing Malus domestica 'Delcorf' indoors is impractical due to size.

Life cycleMalus domestica 'Delcorf' (commonly known as apple 'Delcorf') begins its life cycle as a seed, which, under the right conditions of moisture and temperature, germinates and emerges as a seedling. The seedling grows into a young tree through a vegetative stage, developing a root system, stem, and leaves. As it matures, the tree enters a reproductive stage where flowers are produced; these need to be pollinated, often by bees, to set fruit. Following pollination and fertilization, the flowers develop into fruit (apples), which grow, ripen, and are usually red when ready to be harvested. Once the fruit is picked or falls, seeds within the apples have the potential to start the cycle over if they reach a suitable environment. Beyond fruit production, the apple tree continues to grow and can produce fruit annually for many years before eventually senescing and dying.
PropogationPropogation time
Late Winter to Early Spring
The most popular method of propagation for the apple tree 'Delcorf' is through grafting, which is usually done in late winter or early spring when the rootstocks are dormant. In this process, a scion, which is a short piece of stem with two or more buds, is taken from the desired apple tree. Then, the scion is joined onto a rootstock, which is a young tree or root with an established root system. The grafting site is then sealed with grafting wax or tape to prevent drying out and infection. This creates a new apple tree that combines the fruit-bearing qualities of 'Delcorf' with the vigorous root system of the rootstock. The grafted tree will begin to grow and can produce fruit in a few years, replicating the characteristics of the 'Delcorf' variety.
