Blackberry and Raspberry Trellis
I have question regarding trellising blackberries and raspberries. I currently have 4 berry beds which are roughly 30 feet long and 4 feet wide. Each bed is separated by a 3 foot path of grass. I've done some serious research into different trellis designs and as a result, assembled my first trellis.
The trellis consists of 2 4x4 posts with 2 2x4s attached like a "T." The 4x4 post is roughly 5' tall above ground. The first 2x4 is placed 2 ft off the ground and is 24" in width and the second is placed 4 ft off the ground and is 36" in width. I'm using turnbuckles and strong clothes line for my wires that connect to the 2x4s (4 wires total).
In Bed #1 - I have a black satin blackberry, 1 heritage raspberry and 2 jewel raspberry. Bed #2 - I have 2 heritage, 1 Anne and 1 jewel raspberry Bed# 3 - All fall bearing golden raspberries, species unknown Bed#4 - 1 Apache and 1 Navaho and hopefully 2 Darrow blackberries.
Now to my questions, sorry for all the detail!! Given my trellis design above, I feel pretty good using this on Beds 1, 2, and 4 but what are your thoughts on the bed of fall bearing golden raspberries? I plan to mow these down at the end of the year and am not quite sure if my trellis design is overkill. I've already purchased all the wood according to my trellis design so at this point, money is not an object. I'm just hoping to find the best design.
Question #2 - In terms of the 2 Darrow blackberries, I purchased them roughly 7 weeks ago at Lowes. They were 1 year cuttings so there were pretty small. I soaked them in water prior to planting and have kept the ground moist ever since. But these 2 plants have not shown any sign of growth...no new sprouts. We did get warm temperatures pretty early this year in Ohio so maybe they dried out? Is this common or should I right them off and order 2 more? I'm running out of time for blackberry shipping in May so this has me in a bit of jam.
Any help you can provide would be greatly appreciated!!!
