Thanks for the enlightenment
@Gourmet Hawaiian Kava . I've done some very amateur gardening and I've learned some plants grow their roots down, others grow them out and not so far down. Most of my peppers I've grown have been in pots, so I haven't had a nice outdoor spot to let them spread their roots to the extent that they would go naturally, but I know they like shooting them farther down. It must be some kind of strategy to optimize water availability.
