I really did NOT pay all that close at the roots area when I cut mine.I had a neighbor let me have
plants off some property he has 4 sale out here.I've took about half the side shots& I would guess& I don't think any were shorter than a foot.I took 3 the 1st year and more this year.The ones I took 1st have not set off any side shoots,but I used an axe& a shovel.Mines a basjoo& I don't know if other cultivers are different.I know some shoot off more pups than others& that they recomend that the pups have a start of their own roots.BUT they don't have 2 have roots to sprout.I had a portion that I tossed against shed cause it had no roots.& a month or so latter it started
growing.I'd guess grown from tissue?I just dug a hole& dropped it in.it really needs a sunnier spot.
So tell me more about your
plant& grow condtions.are they pot grown?inground?I use to watch Alan titmarch on our BBC.They would add some pea gravel to their inground mix.I imagine for drainage& watch the winds.high winds will shred your leaves.they'll still live,but the leaves look tattered& will yellow sooner than not shredded.and they like fertilzed.
