| Does anyone have any pointers on rooting trailing blackberries? Will they root anywhere along the cane if pinned to moist soil? Is it best to wait till fall? Mine are still growing ~2 inches a day. Kinda hard to pin down the tip. Do you just bury the tip in soil? How deep? Any other rooting methods? |

| When I propagated boysenberries I just pinned the tip into a 1 gal container and threw a little additional soil over the tip, then kept the soil moist. Considering that they seem to root spontaneously whenever they are even in sight of the ground, it should be fairly simple. The same worked even for the upright growers like Triple Crown. You could stub the canes, wait for branching and then pin each branch to accelerate the propagation progress if you want to make a lot of clones. |

| For my blackberry, I just bend the long canes, rub off the leaves, bury them in soil. I can do this twice or three times with a long cane.By next spring, they should be ready for transplanting. |

| Steve: My black raspberries are like yours. The canes bow over naturally and root anytime they touch ground. Maybe the trailing type would do the same if I let them hang straight down. Maybe hanging down slows the vegetative growth and increases rooting?? Thanks for the input! |
|
| Redsun: Maybe I could just bury the last 2-3ft of cane and see what happens. Thanks. |

| Fruitnut one way is to use clonex rooting gel or another rooting hormone on the part you bury. I bend the cane over and bury it deep enough to be in the moist ground. In Kansas that's 4 inches or more because anything more shallow drys out daily from the hot sun. I don't have much experience with air layering but I do know they peel the top layer of bark back similar to the method I'm suggesting. Another trick I use is I start the plant in sand or another loose medium so the roots can grow faster and it can be transplanted easier so just use hard soil on top to hold the moisture in. |

| ClarkinKS: I probably can't go too wrong trying anything. The canes are already longer than needed for next yrs crop. It's just that these trailing seem different than erect berries. They grow faster. Thanks for the input! |
|
| Fruitnut I grow a couple of acres of the erect type my grandfather grew and they grow both by runners and by seed but with thorns of course. They have been in my family for almost 100 years and get 15'-20' tall. I hope your new starts do well for you. My friends who grow that type here support theirs on wire trellises made from close line wire and t-posts. I suggested barb wire might be cheaper because I have seen people use barb wire to trellis grapes in Nebraska. Let us know how it turns out. |

| I'm afraid blackberries grow down just as readily as up; all of my temporary cane placements on the trellis in summer head straight for the ground with no inclination to curve up, like most plants would. |
|
| fruitnut, I have several varieties that have started tip rooting (layering) within the last two weeks. September seems to be the month that it occurs the most often for me. Moist soil helps. Siskiyou, Wild Treasure, and Kotata have rooted in recently. My trailing varieties are still growing but I have noticed some color changes in the leaves, so I think they are starting to slow down. |

| larry: Blackberries are strange plants. They never branch unless tipped. They grow down, root, and grow back up. The black raspberries do seem to thicken up as the shoot approaches ground and root. jt: I'm thinking Sept and even Oct here will be my best bet for easily rooting these things. Those Columbia Star plants are amazing. The one in a 3 gal pot has 10 shoots averaging 12-14ft. I have to water it 3 times a day to keep up. I'm planting it in-ground this winter so I can get away from it once in a while. |
|
| My Columbia Star haven't been that vigorous but they seem to be growing well. I think my cane lengths on those would be around 6-8ft but generally not more than 4-5 canes per plant. My Newberry has been the most vigorous new blackberry with growth similar to what you have on the CS. The longest cane award this year goes to Kotata, which I measured this morning at 19ft. I have its canes going in both directions on the top trellis wire and it looks pretty impressive seeing one plant stretch almost 40ft across. My biggest surprise has been my single Black Diamond trailing blackberry. Last year the plant had one cane that was barely 3ft long and this year it has 5 canes, 4 of which are over 10ft. I have no idea what happened to make it grow this year. |
