Growing from seeds
Most fruit trees cannot be grown single-variety from seeds because they - especially apple and Pear trees - are often self-sterile and therefore have a second, suitable variety for fertilization require. After pollination by the wind or by insects and subsequent fertilization, a fruit with germinable seeds grows. However, these contain the genetic makeup of both parent plants and are therefore not uniform. Plants by sowing These seeds are obtained, therefore do not fall true to the variety. They are known as wildlings or seedlings. Even self-pollinating fruits like most peaches and plums are not propagated by sowing because they are not sure to fall true to the variety.

But seedlings also have other disadvantages:
- They grow very quickly at a young age and can get very large.
- On the other hand, they will bear fruit later - you have to wait a long time for fruits.
- It can also be an undesirable Thorns appear.
Asexual reproduction
The asexual reproduction from parts of plants is called "vegetative reproduction". If another variety is used as a rhizome for asexual propagation, i.e. refined, this is referred to by experts as "xeno-vegetative propagation". The plants resulting from asexual reproduction are those that are identical to the mother plant.
Cuttings
Propagation by cuttings takes place during the period of dormancy, between November and February. In doing so, you cut annual sticks that are about as thick as a pencil and must be 15 to 25 centimeters in length. You should also mark on the wood where is up and where is down. If the log is stuck upside down, it will not grow on - because then the roots would have to form in the crown. The cuttings are stored in a slightly moist substrate as cool and dark as possible until they are plugged. The stick itself takes place in spring, either directly in the prepared field or in planters under glass.
Cuttings
In contrast to cuttings, cuttings are inserted immediately. The best time for this type of propagation is late spring and early summer. Then cut from the plants to be propagated freshly sprouted, but already firmer shoot parts with a length of about 10 to 15 centimeters. Remove the lower leaves and put the shoots in unfertilized Potting soil. It is important that the substrate is always kept slightly moist.
Tips
Another form of propagation is mossing, in which quite large plants can be grown within a short time. This method is mainly used in bonsai cultivation.
