Very nice! Of my 8 rhizomes planted, 4 are doing very well, 2 are mediocre, and 2 are slow. I have 2 that have produced bines up to 15' and one up to 12'. I have one at about 9', two at 3 to 4', and two that don't seem to want to climb beyond 2' depite a ton of bines popping through the ground. I just posted a few pics on my thread. Like yourself, I'm getting some burrs forming. One of the cascades is absolutely loaded with burrs, one of the chinooks has a fair amount, andthe other cascade is just starting to form a few. I had an issue with the natural fiber twine that I used for climbing lines rotting at the bottom with the ends being staked slightly below grade. My hallertau was the fastest out of the gaits and was up to 6' very quickly when I came home from a weekend out of town and there had been storms. Several of my ropes had rotted and the high winds snapped the climbing bines on those plants, so I have been struggling to retrain the later developing bines that have emerged to climb. I have since fixed my rope rotting problem and added more slack to my cables to allow sufficient tree sway, so now it's a waiting game. The slow pokes in my garden are my centennial and glacier. I also had some early issues with aphids, but an organic vegetable spray has solved that issue. Keep us posted on the progress, but it looks like you and I both should have little first year harvest!
