It turns out why people in the village hammer rusty nails into fruit trees, I’ve been doing the same thing for as long as I can remember!

However, there is another effective way to replenish the iron content of trees, but without hammering in rusty nails: by digging a rusty iron object into the ground near the roots of the affected trees, even when they are planted. This step ensures that the plant has access to a source of iron from the very beginning.

In general, a single rusty nail (or some iron object) is enough to achieve the desired effect, but depending on the size of the tree, more than one may be needed. However, as with everything else, moderation is very important: if we use an inadequate amount of “rust”, we can harm our fruit trees more than we use.

Rust increases the acidity of the soil, and in direct proportion to that of the plant, which is not always healthy for trees in all cases and quantities!
