From I have read, well draining soil.
In the Rio Grande Valley it seems that we are on clay and sand. The fields around here are irrigated but in my tests of the soil where I am planting I found the soil to be slow draining.
I am using 60% compost, 20% ground soil, and about 20% peat moss. (helps hold a bit of moisture with the hot south winds) In elevated beds with a earth berm around them.
So far I have 4 rescued Orinocos in the ground, the rest are in pots getting used to the heat and sun.
All the Orinocos have now put out a new leaf
And seem to do 1-3 inches in a day (I may be over estimating).
So well composted, well draining, lots of light, and watering when the soil is damp 3 inches below the surface.
Of course I am NEW to all this and your mileage may very.
