Mess with the bugs heads, yes my Dad planted in this manner one row this, the next something else in the vegetable garden, plenty of variety very little need for poisons, but then he grew up on a farm when poisons were not available.

When we moved from the Highveld to the coast an Indian gentleman who had farmed down here told me of how they planted certain herbs on borders to confuse bugs, if I remember correctly one was the Thyme bush. Not having money to afford pesticides they also mixed certain plants and herbs by crushing them, laying that in water for a week before going out and spraying the cabbages and leafy veg that attracted some unwanted nibblers.

Lovely lesson to remind folk there are other ways of controlling pests rather than poisoning the food you are preparing for the table @lizziesworld
