compost "too clean"

[size=large]By using sterilized compost in the pots do we open the way to any more problems ?[/size]

 

That is the approach I was thinking armandii... As far as I am aware, plants dont have active immune systems, but do develop certain immunities and vulnerabilities through evolution. That is not to say however, that they cannot adapt to environmental changes, so It would be interesting to find out from someone more knowledgeable than me knows more about this.

My guess would be that it prevents more problems that it causes though, otherwise it wouldnt be logical to use sterilized material.

 

Plants often form symbiotic relationships with soil borne micro-organisms. For example some bacteria and fungi convert chemicals that are useless to the plant into nutrients that the plant can use, often in return for something from the plant, such as sugars that get robbed from the roots. There are also good microbes that kill bad microbes.

Perhaps that's what miraflores was getting at?

However, there are also things like vine bad bugs and weed seeds to think about, and I suspect this is why commercially produced compost is often sterilised. I believe the good micro-organisms just find their own way back into the soil.

 

[size=large]Yes ARMANDII, that was my thought.[/size]
