Moving first year Triple Crown blackberries

joeszyAugust 12, 2013

I had a very small patch of Triple Crown I decided to try to rip out last winter because of space issues. Since then, they've since come back in spades, which has a blessing in disguise because now, I have a brand new trellis all set for them in November.

Right now, they are 6 - 7 feet long and trying to tip-root while I try to keep them from doing so.

I'd like to retain some of this first year growth so they'll produce fruit next year after I move them to their new area, but would like to head back the shoots a bit in meantime to keep them under control. My question is, will doing so encourage horizontal growth similar to what would result when you do a "tipping" on a cane? If so, is it better to leave the canes long and singular and just deal with the mess in the meantime before November? Thanks.

Depends on how many berries you are trying for next year.

Because they are being transplanted yet again, I would advise keeping them as is and pruning them in autumn. Any tip-rooting they do between now and then is easily uprooted and pruned off.

Thanks for that info. How much should I prune them back after transplanting and how many canes should I put in each spot? Have wires at 3 and 5 1/2 feet on both side of the trellis. Not hoping for bumper crop, just would be nice to have a few.

You can keep as much growth as your trellis will support, however, there is a compromise here between retaining most of the growth, gambling that there will be little or no transplant shock, or pruning about half the growth off and allowing for transplant shock--and possibly better growth of next year's primocanes.

If you don't need a lot of berries next year, I would prune by about half. If that leaves dozens of leaf nodes, it will result in hundreds of berries next year. Triple Crown will fruit quite low on the main cane.
