If the fruits fall off prematurely, there may be several reasons for this ailment - let's look into this issue in more detail.
One of the most common causes is disease – fruit rot and scab.
In the first case, dark spots appear on the apples, and then the fruit becomes completely rotten - infected apples fall from the tree.
When infected with scab, apples may fall off before ripening - a sign is the presence of brown spots, and the apple itself loses its shape.
To combat these diseases, the apple tree should be treated with a 1% solution of Bordeaux mixture.
The second reason for fruit falling is pests - the codling moth and the apple sawfly. Therefore, the apple tree needs to be treated in the spring against pests.
Another reason is the lack of nutrients – phosphorus, potassium, calcium and other microelements.
Therefore, the apple tree, like other crops in your garden, needs fertilization so that the fruits do not fall off prematurely.
