So do you just cut the bines, dip in root hormone and grow normally.
Sorry for taking long to respond. What you are referring to is taking a cutting. Where you cut off binds and root them in either water or soil. You can either dip them in rooting hormone first or skip that step. Using rooting hormones tend to have a higher success rate, but it will cost you more money and is not always necessary. Propagating from cutting is what jperry is describing two posts above mine.
Layering is similar, but instead of cutting the bines and then trying to root them, you actually do it in the reverse order. You take a bind that is still currently attached to the mother plant and you bury part of the bine. The part of the bine that is buried should start rooting and once it starts rooting then you cut the bine away from the mother plant. Pretty much how cram describes in the post directly above mine.
A convenient way to layer is to layer directly into a pot. Rather than burying the bine in the ground. When you bury the bine in a pot you can then transport it after it roots and after you cut it away from the mother plant.
I have read in the forum that you can take a cutting and root it in water or soil, but from what people have described part of the bine begins to wilt or die off. This tends to be true of other plants that I have taken cuttings from such as tomato and basil.
When you take a cutting you are in battle against time. Can you get the cutting to form roots so that it can support itself before the cutting rots and shrivels away. Sometimes you succeed and your cutting grows roots. Sometimes your cutting die before they root and you fail. I have heard it referred to as "Root vs Rot".
When you use layering, the bine is still attached to the mother plant therefore the bine should continue to grow and receive nutrients from the mother plant while you are in the process of trying to get the bine to grow its own roots that are separate from the mother plant.
I have read here on the forums that both cuttings and layering works on hops. I have not done this with hops so I am speaking from what I have read and I am speaking from my experience with other plants.
With a single hop bine I have read that you can use a technique called "serpentine" layering which could allow you to create multiple rooted crowns with rhizomes from a single bine. I will post a diagram of this technique.
If I am successful in doing this then I will have some plants to trade with locals in the SoCal area. This is my first year trying to grow hops so I don't have rhizomes to trade and I don't want to wait a couple of years for my plants to get healthy enough for me to take a rhizome cutting, so I am using this technique out of necessity. I can't wait for rhizomes so start shipping already so I can test this out.
