on a plantation spacing will effect fruit density plus you need to consider space for followers (offshoots), usually 4 followers. we planted Gros Michel about 12 ft apart (keep in mind the followers) and Gros Michel is roughly the height of basjoo. we now use a double row system spacing cavendish types about 5-6.5 ft (rows are 10-12 ft apart).

i know this is more info than you asked for but these might be things you want to consider; do you want to try and get fruit (density effects plant height & thus fruiting), plus you need to think about the followers, how thick do you want your mat to get.

since i don't care if my basjoos fruit i space about 4-6 ft.
