Quite a few years ago, I received a catalog from a hybridizer in Alabama
(Bernice Miller) who was also experimenting with pH. She found that
different cultivars responded differently - some did best with a higher
pH, some with lower. I believe she concluded that the source (i.e., the
environment in which the seedlings were grown and selected, not the
commercial source) was related to optimum pH. In other words, if it was
hybridized and selected as a seedling in a high pH soil, it did best in
a high pH. And vice versa. Makes sense.
I don't remember what pH levels she was experimenting with - will see if
I can dig out the old catalog.
I wonder how much diversity there would be in pH requirements of
seedlings from parents that do best with high pH. I wonder what pH
commercial gardens strive for. I wonder if different commercial gardens
have different pHs...
Interesting thread....
