The main reason for poor or no fruit production in fruit trees is iron deficiency. However, this is usually only a problem for older trees. As incredible as this method may seem, the problem can be easily remedied with rusty nails in the case of apple, walnut, plum and pear trees. The iron on their surface makes up for the deficiency, but the effect does not appear immediately in the year of use, but only after a year.
How to do the “rusty nail” method?
The first and most important step is to carefully sterilize the nails before using them and only then hammer them into the tree trunk. This is a really delicate operation that must be carried out as carefully as possible to avoid the formation of wounds on the tree trunk, which, if they do occur, can become a path for certain diseases and pests that affect the tree.
The first signs of iron deficiency in fruit trees are the appearance of yellowing leaves, which eventually fall off. Iron deficiency is usually characteristic of soils rich in calcium or when large amounts of limestone are used.
