Tomatoes, peppers, and eggplant are already perennial.
Anyway, I don't think you have to go so far as grafting a perennial rootstock onto an already perennial rootstock. Seems kinda redundant.
on a companion planting scheme of things I don't think tomato's are suitable to plant with potato's normally.
Interesting about the possibility of grafting capsicums ect onto a rocoto tree though, I have a large rocoto so i think i'm going to try it.
ok I will, lmk your postal address and i'll be happy to send you both red & yellow rocoto seed.
I've heard "Devil's Plant" works well as an eggplant rootstock.
Yukkuri, did the seeds get to you? just picked some fresh big reds and have more seeds if they didn't, i put in new guinea beans aswell, don't know why but i feel cuxtoms might not let 'em in.
with grafting onto the rocoto, i'm guessing to cut an upright branch halfway?
I don't have capsicums at the moment so instead i'll just try a tomato, then cut the tomato branch of similar thickness, shape the tip like a flat wedge, make a slit down the rocoto stem and wedge it in?
tape it up ect and see what happens i guess..
