If a cherry tree bears fruit for several years, and summer residents do not bother to apply fertilizer, the situation becomes close to consumerism.
Another year or two and the harvest will start to get smaller. Therefore, cherries, like other crops, need to be fed according to a schedule.
First, you need to take several factors into account. First of all, the age of the tree.
Secondly, the time of year.
Thirdly, the type of fertilizer.
They say that cherry trees are not fed for up to 2 years after planting. But this statement is only true if all necessary additives were added during planting and the tree grows in fertile soil.
In this case, you can add additives under a three-year-old tree. Once a year, a complex fertilizer is added and 1-2 times, leaf treatment is carried out, also complex.
Fruit-bearing trees are fed twice a season - when leaves appear and at the beginning of flowering. Another feeding is carried out during the period of ovary appearance and berry ripening.
Adult trees are fed with mineral fertilizers once every 2 years.
In early spring, a mixture of nitrogen, phosphorus and potassium (nitroammophoska or ammonium nitrate) is added.
After flowering, foliar feeding with urea is carried out.
In autumn, a phosphorus-potassium mixture is added (superphosphate and potassium sulfate or potassium monophosphate).
