Re: CULT: rscorch

I guess the best way to describe it would be to position the rhizome so that the fan casts the smallest shadow.  If the fan catches most of the sun in the morning or afternoon, then the shadow will be big. That is when scorch occurs.  If you turn the fan 90 degress or so, the shadow gets smaller.  You do not want the morning and afternoon sun hitting directly on the front and back sides of the fan.  You want it hitting the side of the fan in the morning, the top of the fan in the day, and the other side of the fan in the evening.  If the sun rises in the northeast and sets in the southwest as it does here, then you want the toe of the rhizome facing a northwestern direction. 
 
If anyone understands this and has a better way to explain it, please help.

The sun shines from the North here. Should I position the plant with the fan
facing North (rz facing south) or the fan facing East (rising sun) or west
(setting sun)? I can see your reasoning, but I'm not quite sure of the
positioning you describe.
It gets blisteringly hot here in summer, and I've lost a few to scorch. I do
find that the plants established on pots seem to fare better.
