From a tree at the age of 12, it is possible to collect about 100 kilograms of fruit. A record yield was also recorded - a little over 200 kilograms were collected from one tree of the Zvezdochka variety.

Consumer ripeness of fruits occurs at the stage of storage of apples. As a rule, apples reach full maturity in mid-October. The fruits of this variety are characterized by excellent keeping quality. Apples can be stored in stores for more than six months. Subject to storage conditions, the quality of the fruit remains high until March. The shelf life of fruits in an ordinary basement exceeds five months without loss of commercial quality and appearance.

Landing and care

Disembarkation is carried out in late April or early May after complete snow melting and in the absence of frost. The Zvezdochka variety does not adapt well when planted in the autumn. The apple tree needs good lighting, and it is recommended to plant a fruit tree of this variety on an open southern, southeast, or southwest site. The presence of shade significantly slows down the growth of the apple tree, reduces its productivity, and the fruits lose their color and taste. Landing area should be carefully dug up and loosened.

Saplings of the Zvezdochka variety are planted in deep, wide pits with fertilizers in the form of peat and wood ash. Vertically located seedlings are installed in the central part of the planting pit. The root system is distributed and sprinkled with fertile soil, which is slightly compacted. The root neck of the plant should rise above the ground by six centimeters. Near the plants, it is advisable to make grooves that contribute to the outflow of excess moisture from the roots of the tree.

The first top dressing is introduced in the spring at the planting stage. It is allowed to replace peat with wood ash with humus or horse humus in the amount of one bucket per square meter. In the autumn, complex fertilizers without nitrogen are required. The presence of fertile soil significantly reduces the need for fertilizing.

The Zvezdochka variety is demanding on pruning, which increases yield and is the best option for disease prevention. Pruning is important every spring before the leaves bloom. The variety is characterized by insufficient frost resistance, which requires mulching the soil around the plants in the autumn. Hay, peat, bark or sawdust can be used as mulch.
