In June, fruit trees like to drop fruit by themselves. If you want to prevent this, then you should thin out the fruit.
The tree can no longer support the fruit
Have you ever noticed that many fruit trees shed their fruit? Don't worry, it's perfectly normal and it's the way it should be. Because the tree gets rid of these fruits by itself because it simply can no longer provide for them. Fruit that is lying on the ground should be picked up and discarded immediately as it can be a breeding ground for disease. Since not every tree produces enough fruit, you should lend a hand and check the trees yourself.
To thin out the fruit:
Any fruit that is closer than a hand's width apart must be broken out, as must any fruit that is in twos or appear in threes. Except for one fruit you have to break out all the others. This reduces the risk that diseases can spread to the entire tree due to rotting fruit that is no longer supplied. In addition, the other fruits get more nutrients, become larger and also tastier. Don't think that if you don't pluck the beautiful fruit, it's a waste of it, because you'll end up harvesting a lot less.
