Introduction to apples
Apple trees are a delightful addition to any garden or orchard. These beautiful trees, not only provide shade and visual appeal but also bear delicious and nutritious fruits. With their rich history and wide variety of cultivars, apple trees have captured the hearts of gardeners and fruit enthusiasts for centuries. Whether you're a seasoned gardener or a beginner, growing apple trees can be a rewarding and fulfilling experience.
The history of apple trees is a fascinating journey that spans thousands of years. Apples have been cultivated by humans for centuries, and their origins can be traced back to the wild apple trees of Central Asia. The cultivation of apple trees began around 4,000 years ago in ancient Mesopotamia (modern-day Iraq). The ancient Greeks and Romans also recognized the value of apples and cultivated various varieties. Apples were not only enjoyed as a tasty fruit but were also used for medicinal purposes.
In the 17th century, European settlers brought apple trees to North America, where they thrived in the new environment. The apple became an important part of American culture, with settlers using apples to make cider, pies, and other culinary delights.
Apple trees have become a symbol of abundance, health, and temptation throughout history. They have inspired myths, folklore, and even played a role in religious stories, such as the biblical tale of Adam and Eve. With their rich history and cultural significance, apple trees continue to be cherished by gardeners and fruit enthusiasts worldwide. Whether you're planting a single tree in your backyard or tending to a vast orchard, apple trees offer a connection to the past and a delicious bounty for the future.
Apple Trees vs Cider Apples
The main difference between apple trees and cider apple trees lies in the purpose for which they are primarily grown.
Apple trees, in general, are cultivated for their edible fruit, which can be eaten fresh, used in cooking, or made into various products like apple juice, applesauce, or pies. These trees are often selected for their flavor, texture, and sweetness.
Cider apple trees, on the other hand, are specifically grown for the production of cider, a fermented alcoholic beverage made from apples. Cider apple trees are typically chosen for their specific characteristics that contribute to the flavor, acidity, tannin content, and aroma of the resulting cider. These trees may produce apples that are less palatable when eaten fresh but are ideal for cider-making due to their unique qualities.
Cider apple varieties are often categorized into four main types: bittersweet, bittersharp, sweet, and sharp. Bittersweet apples have high tannin and sugar content, providing body and flavor to the cider. Bittersharp apples have high tannin and acidity, contributing to the cider's structure and balance. Sweet apples add sweetness, while sharp apples bring acidity and tartness to the final product.
It's worth noting that some apple varieties can be dual-purpose, suitable for both fresh consumption and cider production. However, cider apple trees are typically selected and cultivated specifically for their cider-making qualities.
Apple Tree Planting Location
Apples are best planted in full sun, that is, an area that gets at least 6-8 hours of direct sunlight per day. Moist, but well drained soil is preferred.
Apple Tree Fertilizing
For new plantings, use bonemeal or myke in the planting hole. You can also use liquid transplant fertilizer when watering to promote root growth and development. For established plants, use a Fruit Tree and Berry food in early spring before new growth begins
Apple Tree Pollination
Apple tree pollination is a crucial process that ensures the production of fruit. Most apple trees are not self-pollinating, which means they require cross-pollination from another apple tree of a compatible variety to produce fruit. Here's how apple tree pollination works:
-
Flower Structure: Apple trees produce flowers that contain both male and female reproductive parts. The male parts, called stamens, produce pollen, while the female part, called the pistil, contains the ovary where the fruit develops.
-
Pollination Agents: Pollination can occur through various agents, including bees, other insects, wind, or even human intervention. Bees are the primary pollinators for apple trees, as they are attracted to the flowers' nectar and inadvertently transfer pollen from one flower to another as they move between them.
-
Pollen Transfer: When a bee visits an apple tree flower, it collects pollen from the stamens. As the bee moves to another flower, some of the pollen grains are deposited onto the sticky stigma, which is part of the pistil. This transfer of pollen is known as pollination.
-
Fertilization: Once the pollen reaches the stigma, it travels down the pistil to the ovary, where fertilization occurs. The pollen fertilizes the ovules, leading to the development of seeds within the fruit.
-
Fruit Development: After successful fertilization, the ovary begins to grow and develop into an apple. The seeds within the apple are the result of the fertilization process.
-
Cross-Pollination: To ensure successful pollination and fruit set, it is important to have apple trees of different varieties that bloom at the same time. This allows for cross-pollination between the trees, as pollen from one variety is transferred to the flowers of another variety.
-
Pollination Compatibility: Not all apple tree varieties are compatible for cross-pollination. Some varieties have overlapping bloom times and compatible genetic traits, while others may not. It is essential to choose apple tree varieties that are known to be good pollinators for each other.
-
Pollination Challenges: Factors such as weather conditions, lack of pollinators, or limited availability of compatible varieties in the vicinity can affect pollination success. In such cases, hand pollination or the use of pollinator-attracting techniques may be necessary.
An apple tree triploid refers to an apple tree variety that has three sets of chromosomes instead of the usual two sets found in diploid apple trees. One significant characteristic of triploid apple trees is that they typically produce sterile pollen. This means that they are unable to effectively pollinate other apple trees or even themselves. As a result, triploid apple trees are primarily used as pollen-sterile cultivars in orchards, where they serve as pollination partners for other apple varieties.
By understanding the process of apple tree pollination and ensuring the presence of compatible pollinators, you can increase the chances of a successful fruit harvest.

Apple Tree Pruning
Pruning an apple tree is an essential task that helps promote healthy growth, improve fruit production, and maintain the overall shape and structure of the tree. Here are some general guidelines to follow when pruning an apple tree:
-
Timing:
The best time to prune apple trees is during late winter or early spring, while the tree is still dormant before new growth begins. This allows the tree to heal quickly and minimizes the risk of disease transmission.
-
Tools:
Gather the necessary tools, including sharp pruning shears, loppers, and a pruning saw for larger branches. Make sure your tools are clean and sharp to make clean cuts and reduce the risk of damage to the tree.
-
Remove Dead, Diseased, and Damaged Wood:
Start by removing any dead, diseased, or damaged branches. These can be identified by their lack of foliage, discoloration, or signs of decay. Cut them back to healthy wood, making clean cuts just outside the branch collar (the swollen area where the branch meets the trunk).
-
Thin Out Overcrowded Branches:
Look for branches that are crossing, rubbing against each other, or growing towards the center of the tree. Selectively remove some of these branches to improve air circulation and sunlight penetration. Aim to maintain an open and balanced canopy.
-
Maintain the Central Leader:
Apple trees are often pruned to have a central leader, which is a dominant vertical stem. Encourage the central leader by removing competing branches that are growing upright and taller than the leader. This helps maintain the tree's desired shape and structure.
-
Prune for Fruit Production:
To encourage fruit production, prune to create an open canopy that allows sunlight to reach the inner branches. This helps promote bud development and improves fruit quality. Remove any water sprouts (vigorous vertical shoots) and thin out excessive fruiting spurs to prevent overcrowding.
-
Step Back and Assess:
Throughout the pruning process, step back occasionally to assess the tree's overall shape and balance. Aim for a well-proportioned tree with evenly spaced branches.
Remember, these are general guidelines, and specific pruning techniques may vary depending on the apple tree variety and your desired outcome.
Apple Tree Care & Maintenance
Apple a Dormant Oil / Lime Sulphur Spray is late winter to early spring to smother over-wintering insects and reduce the likelyhood of disease. Apply a 2-3 inch layer of mulch in fall to help the apple tree over winter.
