And on the side of predators is there no way to favor, pamper, "cultivate" the carabid population?
I think they like hedges ... but it's true that they were destroyed a lot at one time
The carabes just like the covered areas: meadows, etc ...
The sheet cited below says: "Tillage, and more particularly plowing and
le deep work increase the risk of nuisance on beetle populations. The sowing under cover,
theresidual grass as well as organic matter input are favorable to them "
In short, make a "Lazy Vegetable Garden"! Laziness pays off !!! I know, it's not moral !!!
This is one of the reasons for the maintenance of grassy paths between my flowerbeds, and hedges all over the northern border, all without borders around the flowerbeds (so as not to put any obstacle).

[I observed yesterday the first golden beetle - carabus auratus; I had already seen black carabids, no doubt: Pseudoophonus rufipes
