Hey, hoping that some of the hop growers made it here from the other board. I have a few hop mounds that I planted last year and should start sprouting here soon (I live outside of DC, its still been cold.) Does anyone here have experience with propagating established hops? I'd like to maybe double how many plants I have but don't want to do anything that would hurt the established plants or lower their yield by much...

How are they planted, in the ground, or in containers? Either way, a little gentle digging from the periphery will lead you to see what you have in the way of rhizomes. You can prune a few with sharp shears or rosebush pruners, or a sharp blade. Look for a sprout or more on the section, and repeat planting like last year.Mine here by Chicago are allready sprouting, with cascade in the lead with 14 sprouts on one crown, and Centennial with half dozen on each.

They are in the ground, and while we've had a few warm days its been going below freezing at night. Hopefully that's done now that we're almost in April. I'll wait until I see some sprouts come up and then follow your advice. Do the roots that are important for growth this season mostly go straight down, and things I see coming off laterally with buds are fair game?

My cascades spread like crazy this spring. Once the shoots came up I was able to gently dig around them to find the rhizome and cut with a sharp knife. The shoots were probably already about 4 inches tall when I did this. I expected the shoots to at least wither a little from the replanting. They look really healthy and didn't wither, but the replanted ones are growing much slower than the original planting. I guess once the roots get established they will take off.Some of the vines are already 4' tall.

Sorry, I actually meant buds, not sprouts. :) As far as the roots go, mine are in all directions, so only the hops know for sure. The deeper (tap) roots are for drought resistance, as they seek water.

Just got my rhizomes from William's yesterday. I assume I can keep them until this weekend when I plant them. Wrapped a wet paper towel around the root. Any issue with that? And, how deep do you plant them or how much of the top do you leave out or do you just bury the whole thing and let it fight for the surface. William's says it has instructions on their site, but they don't.

They will be fine in the damp paper towel for a week or two. I kept a couple in my fridge last season until the ground warmed up. When I planted I built up some mounds, mixed in some better soil at the top, and put the rhizomes like 3" down in the mounds. I also put down a bunch of mulch to keep weeds etc. out of the mounds. They really will grow quickly if you prepare where you plant them and get them the right amount of water.

Thanks for the link. The rhizomes looked good. Already with some growth.

Last year, it was almost 3 weeks from the time I received my rhizomes to when I had them in the ground. When I went to plant it, there was almost another inch of growth compared to when I received it. I was worried that I waited to long, but it really took off and did well for a first year.

Obviously it's too late now for this year, but the best way to propagate is to bury bines in the fall, then dig them up in the spring.

I waited ~3 weeks maybe more before planting mine this year. I just tossed the ziplock bag in the back of the fridge. It took less than 4 days for it to sprout once I planted it.
