I take this remark to say something, namely that I believe that as a "natural" gardener, who tries to have biodiversity, auxiliaries, life in the vegetable garden, it also depends a little (a lot) on the neighborhood ...
if we are surrounded by vegetable gardeners "chemists", in bare soil, followers of the tiller, treatments at all costs, the populations of auxiliaries will not be able to develop as well as if everyone "played the game".
Alas my neighbor is an irreducible and the other, two houses away, the same. Fortunately there are still their large cherry trees, at least they are free from treatments and sprays (which is not the case for young apple trees, however)!
On the right, one who does not garden, but a swimming pool ...
And behind, plowed fields, conventional agriculture.
So I'm a little stuck ... besides, my land is small. Just a "small island" of limited biodiversity.
well, there are browsers anyway ... and even slugs and some mole rats
