Wormy apples are not a sign of "naturalness" at all. They are the result of a codling moth attack.
The butterfly lays eggs in the ovaries, and the caterpillars eat the fruits from the inside.
Chemicals only temporarily solve the problem, but there is a way that agronomists are silent about.

A month before the apple tree blooms, dig a 15 cm deep groove around the trunk and place fish heads and tails in it.
As the fish decomposes, it releases nitrogen and phosphorus, which strengthen the roots and repels butterflies with its pungent odor.
The depth of the planting will not allow the smell to bother you, but it will remain noticeable to insects.
Additionally, sprinkle the soil around the tree with a mixture of mustard powder and wood ash (1:2) - this will create a barrier for caterpillars.
If there is no fish, use human hair (collected from a comb) - it contains keratin, which the codling moth avoids. Bury it around the perimeter of the crown to a depth of 10 cm.
After flowering, hang containers of fermenting kvass or beer on the branches - the smell will attract ground beetles that eat the caterpillars.
When the apples reach the size of a walnut, wrap each fruit in a paper bag soaked in tea tree oil to repel butterflies.
In the fall, be sure to collect all fallen fruit and bury it outside the area - caterpillars overwinter in the soil under the tree.
If this method seems radical, try "trapping belts": wrap the trunks with burlap smeared with honey. The butterflies will stick before they have time to lay eggs.
Store the harvest in boxes with dry wormwood - its essential oils kill the larvae remaining inside the fruit. Now your apples will be clean, and your neighbors will start looking at the branches bursting with perfect fruits.
