When cutting Oldhamii for propagation questions
1) How many culms should you get from a 20-30 foot plant? I'm guessing 15 or so before the culms are too thin... Is that correct?
2) When pruning off branches, should I just cut close to the node or totally take everything off of it?
3) If I cut a 10' long section, would I be able to transfer the whole section and separate the culms and bury them for propagation later? or once it's cut does it immediately have to go into soil for it to survive?
4) For the lower nodes that are already bare, If they are buried, will they develop viable branches or are they done once they are bare?
That's all I can think of right now. I'm going to get some cuttings this weekend and I'm trying to figure out how much soil and containers I'll need. Thanks.
