Leverhead, It looks like your plants are doing great. My orientals are ranging from 3-4 ' at the moment. They have a ways to go yet before I s..t my britchs. ha ha I,ve got some plants topping out in the 5' range and starting to bud as of this morning. I've got 1 each... havana 41, Perique, and silk leaf bagged so far.
I finished that article on the soil surveys and 100 yrs ago some of these areas were just getting settled, It may just be my interpretation but They seem to have specificly chosen far ranging areas in Brazos valley, which is bigger than some states to conduct there survey. I would have to double check on the palestine area but we both are probably growing in similar soils.
