Natural garden at any cost?

Hello, my sister is very focused on organic and wants to have it that way in her garden. Now she has problems because the neighbors do not like that the seeds of weeds, as they call them, fly into their gardens. What can be done to keep the peace in the neighborhood?

With something like this, it is always difficult to convey, because if someone values a well-kept garden, then every dandelion from the neighbor's garden is an attack on their own garden. But a natural garden does not have to mean that the weeds spread all over the area. A bio garden is often mistaken for a wilderness!!

I believe there are few things on which opinions differ as much as here. Whoever stands on English lawns quickly gets annoyed when a weed appears. But it is such that one probably has to accept it when seeds fly around. That's just nature!

In a natural garden there is actually no weed, one always thinks that such a garden is not maintained but that is not true. Rather, care is taken that only native plants grow there that provide enough food and shelter for our insects and birds.
