The science of these great ferns is that evolved to sometimes fall, and then root again lying down, grow up to 10 or more feet and then fall again. Over the centuries one hapuu fern can "travel" 30 or more yards. (Some of the giant, centuries old hapuu at Volcano Art Center's Niaulani Nature Walk are apparently rooted in super deep soil.)
Even though hapuu will grow if fallen, I need to keep some of my Volcano hapuu erect. I've been piling dirt around their bases, 2 or more feet of it. Some are leaning at a 45% angle. I used to just prop them up with a thick piece of guava, but gravity eventually wins here.
I'm also piling dirt around some stunted hapuu, 4 feet tall and old, growing in only 4-6 inches of soil (lava shelf underneath). On occasion you see a big hapuu growing in a place with minimal soil, but mostly they need a lot of dirt. Any one have any tips or observations on this subject? Mahalo.
