Is it a modern observation or old folk-law? Without explanation, it's a system which simply demands adherence to rules without understanding, and that's not something I can live with

Hosting innocuous fungi also helps to fill the niche that would otherwise be waiting for the pathogen. Other studies have shown that certain areas in San Diego have something in the soil that is antagonistic to Phytophthora but these concepts just sit there in dormancy until some college student like myself comes by willing to pour in our time for a grade. I'm sorry to have gotten so off topic but this notion of selective funding is frustrating and dear to my heart.

These include trap crops, dynamic accumulators, nitrogen fixers, mulchers, etc. I hope that helps.

Two of them were planted right next to other plants, while the other 3 had lots of empty space around them. All 5 were planted in soil of equal quality - pretty sandy with a little composted cow manure mixed in. They were all mulched with a couple of inches of shredded oak leaves/pine straw mix. All 5 are in full sun all day, and have received about the same amount of water.
I thought that perhaps the two that were planted close to other plants might not do as well because of the competition they would have to endure. However, the complete opposite has happened. Those two plants are now 24 inches high and wide and 3 to 4 times more massive than the other 3. The two "companion plants" are similar - one is apple mint and the other is greek oregano.
Is this an effective companion plant combo? Or is it just a coincidence? It would be interesting to see if anyone could duplicate this "experiment" and help answer that question. Or maybe someone's already seen something like this?

my first response to the topic is that i do not believe that most companion plants (or guilds) work everywhere. it seems to me that soils, climate, etc will influence what plants like each other or do well together.
