How long does an apple tree live and what does it depend on?
The apple tree is the most common fruit tree in our country. The Greeks brought this culture to Europe, in Russia they learned about apples in the 11th century. One hundred years later, the plant has already been successfully grown and used. Of course, this tree was not yet what we know it at the present time, and many species simply did not exist. Today, the diversity of apple varieties in Russia is entirely the merit of modern breeders.
Apple tree: general characteristics
Modern plants originate from their wild ancestors, which for a long time were "domesticated" by people. The Sievers apple tree is a powerful tree with a trunk height of up to 14 meters, which once grew in the foothill regions of Kazakhstan and Central Asia, has become the ancestor of all cultivated species.
To date, in the middle lane, the most common domestic apple tree is Malus Domestica. Depending on the variety, trees can reach a height of 2 to 7 meters, begin to bear fruit in the second, fifth and even tenth year of life. As a result of hybridization, many varieties are self-infertile, so they require cross-pollination with other similar species.
Thanks to the work of breeders, small compact plants have recently appeared that are more convenient for growing, caring for and harvesting.
The apple tree belongs to the Rosaceae family, in which there are up to 60 different species, including wild ones. Among them there are not only trees, but also large shrubs with a height of about 11-12 meters. By the way, they are also used by man - for forest shelterbelts in arid regions.
Due to the fact that a tree has a lot of advantages, consisting in high productivity, a certain unpretentiousness to the soil, resistance to cold and relatively simple care, it is always in demand. And, of course, it is important for gardeners to know what the life expectancy of this culture is.
On average, an apple tree lives no more than 40-50 years, hybrid crops usually remain viable for about 30-35 years, but there are some cases when an apple tree can live up to 100-150 years. But the life span of wild varieties significantly exceeds the life cycle of cultivated plants; these species sometimes live up to 200-300 years. To understand why there is such a big difference in terms, one should consider all the circumstances that affect this aspect.
What affects the lifespan of a tree
On how long the apple tree will live, and also, how many years it will bear fruit is influenced by a number of important factors:
- The terms of life and fruiting can be directly affected by various types of vegetative propagation, in particular, rootstocks - plants for grafting, which increase early fruiting and improve crop yields. But it is known that early-growing varieties, for all their advantages, have a lower life expectancy.
- Of great importance is the area where the apple tree is cultivated. In the northern regions, with prolonged exposure to cold, insufficient light and heat, plants die the earliest. In the middle lane with its temperate climate, trees, in most cases, can reach a cycle of 60 years.Long-livers are considered varieties growing in the south. In addition to the fact that they live from 80 to 100-120 years, they can even bear fruit at such a mature age.
- Proper and regular care of a crop such as an apple tree is very important. You need to start by choosing the most convenient place for the tree - sunny, calm, with good soil and average humidity. Seedlings are planted in accordance with all the rules of agricultural technology, after which they need timely watering, fertilizing, weeding, pruning. Sanitation from pests and diseases can also increase the life cycle of a plant.

When purchasing a seedling, the gardener must know the characteristics of the selected variety and the subtleties of caring for it, but, along with this, one must have a good idea of how the culture grows and develops, in accordance with its heredity
Features of life cycles
The life cycle of a tree can be divided into several important periods, each of which is characterized by its own characteristics, expressed in age-related changes.
- First stage - this is the growth of a seedling, the development of its root system, the formation of a crown, followed by flowering and the formation of fruits. In apple trees of different varieties, it can proceed for 2-15 years. At this point, it is important for the gardener to follow all the basic rules for caring for the plant. Basically, fruiting and life expectancy depend on this.
- Second period lasts from 15 to 40-50 years with a gradual inhibition of vegetative growth. If the crown is too dense, the interweaving of side branches and other manifestations of insufficient care, the growth on young shoots stops, which leads to the appearance of small fruits, diseases caused by lichens, and a large number of root shoots.If measures are not taken in time, the tree may completely degenerate or run wild. To restore the culture, formative and special sanitary pruning will be required.
- Third cycle is final. The growth of the tree stops, the largest branches that extend from the trunk and make up the skeleton of the crown begin to gradually dry and die off. At the same time, fruiting may decrease gradually, or the apple tree abruptly stops producing crops. Such plants can no longer be restored, so it would be wise to uproot old trees by digging a ditch around them and cutting off the largest roots. Then the trunk is felled, the remaining root growth is removed.
Watching a tree, it is easy to understand when its life cycle begins to come to an end, and at this time you can already think about what kind of apple tree will replace the old one.
Selection and age of apple varieties
It is known that the very first varieties of apple trees grown from seeds, and not using scion and rootstock (that is, grafts), were more viable and lived up to 150-170 years. This is probably why today many are trying to grow a tree from apple seeds.
Such trees have all the positive characteristics - disease resistance, frost resistance, unusual unpretentiousness in relation to the soil. They are stronger and more enduring in all respects, apart from excellent yields. But not everyone is ready to devote so much time to this occupation, because it is much easier to buy a ready-made seedling and, having rooted it, after a couple of years, get a good harvest.
Complaining about the fact that the hybrid variety bears fruit for the longest, 20 years, many people forget that precocity, in the literal sense, costs the plant life.After all, being, in fact, not fully formed, a young apple tree begins to spend a huge amount of carbohydrates, amino acids and other plastic substances on the formation of fruits. As a result, the tree quickly depletes its vitality and wears out.
Unlike hybrids, wild crops of this species bring a crop only for 10-15 years, when all the necessary substances for fruiting have been accumulated, the root system and the aerial part are fully developed.
Also, during breeding, plants are often transported from one climatic zone to another, and, as a result, apple trees become smaller in size, acquire such a property as precocity. Moving them to the eastern regions and Central Asia does lead to a reduction in the life span to 30 years.
So we can say that it is the cultivation without taking into account the important features of the tree that is the reason for the rapid decline in vital activity and the early death of artificially bred varieties of apple trees.
