Triple Crown Blackberries - trellising and care
I currently have a mix of erect blackberries in a bed in my back yard (Navaho, Arapaho, Apache). I have another bed where I want to add Triple Crown (semi erect). That bed is about 28' long and 6' - 7' wide. I can easily extend another 2'+ by putting my trellis stakes 1'+ away from each end of the bed. My questions are as follows:
1) I plan to make a simple two wire trellis. I had hoped that I could treat like trailing varieties, but not sure that will work. In other words, I wanted to allow current year primocanes to sprawl along the ground, while training flouricanes to the trellis. That way after fruiting, I could remove the flouricanes and the following late winter/early spring, train the prior season's primocanes (current season's flouricanes) to the trellis. That next season, I would again allow the primocanes to sprawl on the ground. This would allow me to keep flouricanes and primocanes separated, and would give me a systematic method for trellising the plants. My question is, will this work with Triple Crown?
2) I plan to have one row of 5 plants, spaced between 5' - 6' apart. Does this sound about right?
3) I plan to use a simple 2 wire trellis system, using 3 metal stakes (those green stakes you get from Home Depot/Lowes). Will that suppoort the weight of these semi erect blackberries?
