Clueless Raspberries
2012 is the first season with raspberry canes growing behind the fence.
Last winter I prepared a raised bed with a core from the remnant pieces of the 6′ rotted maple stump that had been a corner of a fugly storage shed (that has been replaced with something more suited to Mrs cohutt’s eye.)
Into this bed four “Heritage” raspberry plants were tucked in along with mulch and a drip irrigation line to keep them happy.
Following the somewhat vague guidance from various state agriculture bulletins, I constructed a sturdy two wire “T” trellis system for support.
As the canes came to life, I searched for pictures showing what a bed of Heritage raspberries might look like inside of a properly dimensioned “T” trellis system. There were a few, but with the massive number of canes that come up in an established bed, the pictures just looked like a mass of modestly contained chaos.
Once my new canes came up I panicked and lowered the height of both wires; now I am contemplating raising them again if I can. It appears that I significantly misjudged the ultimate length of the canes- I figured 5 feet might be about right but these just keep growing.
I “tipped” the main canes two or three weeks back to promote lateral growth, which seems to be working well. Still, what a tangle of thorny canes.
If anyone has experience with raspberries, especially “Heritage”, and the proper trellis system for them, I’m all ears.

I curious to hear from someone with expirence as well. I planted six canes but have no trellis system at all. They produce good berries but it is one ugly mess.
I think this is close to what I need per the various AG bulletins. I’ll cut to the ground in late winter and start over vs thinning and doing the primocane/floricane thing.
from everything I’ve seen, this is exactly what you are supposed to do…. we are planning to try the same. I didn’t know raspberries were so gangly!!
That’s good news. Hope you are right!
