There are plenty of types of apples to grow at home. Evaluate your zone first and the number of cooling hours. Next, envision the area in which you have tolerant an apple tree. Next, decide whether you want to harvest the fruit and whether you plan the fruit to pick early, mid-season, or late. Select two apples out of the same pollination group to yield the best crop.
Many apples quickly grow from seeds. Rather than for other perennial crops, though, apples must be propagated asexually by grafting to acquire the parent’s sweetness and other attractive properties. That is because seedling apples are an example of “strong heterozygotes,” in that they are radically different from their parents rather than inheriting genes from their ancestors to produce a new apple with maternal traits, maybe to cope with the many pests.
Triploid cultivars provide an external reproductive obstacle, as three sets of chromosomes can not be equally distributed through meiosis, resulting in uneven chromosome division (aneuploids). Although if a triploid plant can develop a seed (e.g., apples), it is uncommon, and seedlings never grow.
Apples will grow well in loamy, well-drained soils, even though they thrive in more sandy soils or soils with some clay.
Apple trees will grow best in a neutral soil pH of 6.0 to 7.0.
Apples are better grown in full sunlight. An apple tree placed in limited sunshine does not yield as many apples as an apple tree planted in full sun.
Apples are self-incompatible. They must be cross-pollinated to grow apples. During the growing season, apple growers sometimes use pollinators to deliver pollen. Honey Bees are the most widely used species. Orchard Mason Bees are also used as secondary pollinators in agricultural apple orchards. Bumblebee queens are often found in orchards, but typically not in large numbers to be significant pollinators.
Cultivars differ in yield and the overall size of the fruit, often though raised on the same rootstock. Some varieties, if left unpruned, develop very large, allowing them to produce more apples, but actually make harvesting more difficult.
Based on the tree density (number of trees planted per area), mature trees usually bear 90–440 lb (40–200 kg) of apples each year. At the same time, productivity can be close to zero in the hard years.
Trees grafted on dwarf rootstock produce around 20–180 lb (10–80 kg) of fruit each year.
Apples are picked using three-point ladders built to fit between the limbs.
