Iv seen somewhere on here that someone used stainless steal and bent them into pins. So that should work ok to help root.It's a lot of work - trying to make sure each leaf root actually roots into the substrate. Some sort of 'U' shaped pin could help to keep them down (like a wire tack)...anyone used anything like this that doesn't rust? Also I've noticed that some leaf nodes produce multiple leaves - any reason for this? Is it where the plant has been trimmed?
