In the garden of an experienced gardener, you can find apple, pear, and plum trees with nails in their trunks.
Gardeners resort to this method when old trees stop bearing fruit.
The problem lies in the lack of iron in old trees. To solve it, it is enough to hammer a few rusty nails into the tree.
The nails should be hammered in shallowly. First, one is hammered in, then a couple of centimeters higher – one or two more.
This method is tried and tested and truly effective: the following year, the tree will yield significantly more fruit.
