Re: Re: CULT: pH (was OT-BIO)


Well............ all the data is not in but from the limited data I have now 
the supposition that a rhizome prefers the pH it was collected from, takes 
approximately 18 months to acclimate itself to new conditions then carries on 
as if undisturbed would be more accurate.

Certainly we can hybridize for extreme acid or alkaline tolerance and to a 
degree some plants exhibit this though not necessarily hybridized for 
specifically. Either would serve only a niche market. Plants that did well 
across a broad pH range would obviously serve a larger market. I suspect 
variation in pH tolerance is one of the reasons you get so much diversity in 
the collection of the data you now collect on the performances of different 
irises.

Contrary to conventional wisdom, there are a few Japanese iris that grow in 
alkaline soils though as a group they are notorious in their demand for 
acidic conditions.

Of course all this takes place within certain finite limits that as of now 
are poorly defined
