B.vulgaris 'wamin', getting the internodes to swell
I am looking for information on how (or if) I can coax an in-ground 'wamin' specimen to take on the characteristic bulging internodes.
The specimen showed the "Buddha Belly" shaped culms when I bought it (in a pot) locally. However in 2-3 years in the ground no further culms have the shape, though the plant is vigorous.
I used to have one of these in South Florida and the culms were fantastic. Now I am in near-coastal Southern California where there is a lot less heat accumulation and humidity than South Florida. I'm trying to find out what can be done to get the Buddha belly shape going.
I also have a B. ventricosa "Buddha Belly" and the key to the shape seems to be stressing it with minimal food and watering. However I have been told this will not be the way to get the B. vulgaris 'wamin' to 'belly out'.
