anyone growing p. parvifolia, rubromarginata, dulcis in zone 6?
Just wondering how your boos are doing- I planted a small rubro in 2011 and its still shooting up even now, still very small. Just wondering which ones should get the biggest diameter culms in zone 6a. I've had a nigra henon for 10 years, and the culms are still very thin, maybe about 3/4 inches in diameter this year- last winter it didn't go below 0 farenheit, so it seemed to really like that! If we get another mild winter, it'll probably get even better!
I've got a p. atrovaginata I planted in 2008 (it was 1 gal, small plant), that is finally starting to fill out (about 1/2 inch dia. culms, 6 feet tall and has spread 5 feet or so).
My one incense bamboo was planted in 2009 in crappy crappy soil, I started to fertilize it and pile on hay so hopefully it will do SOMETHING next year, it's got 4 small culms that had looked anemic ever since I planted it. It's about 3 feet tall, what there is of it.
