Howdy VA,
Tepary beans are easier than folks think. They simply prefer their soil very well drained. So, a raised bed, even just 6 inches raised, is preferable for teparies.
Tepary beans will grow as if they are miniature pole beans if they are happiest, but they don't need to be at their happiest to produce. They do well if you put 3 seeds in the soil around a 3 foot rough stick, each of those 3 seeds separated from each other 2 or 3 inches. Don't worry if only 1 or 2 grow, but they tend to germinate pretty well and easily. Water them just the same as any other bean. Once the pods begin ripening, it is best to pick them every few days because overripe pods tend to pop open.
I'm looking forward to growing tepary beans.[/QUOTE]
