If it's happening to more than a couple of leaves, I'd say there is a problem. Moso is hardy to 0 degrees F. I've got moso plants and moso seedlings and they don't lose very many leaves in fall. My seedlings were started last summer (2004) and stayed out all winter in Zone 8 with no leaf loss. What are yours planted in and are they too moist/dry?

Here's a couple pics

That doesn't look so bad to me. The way you described it at first I thought there was nothing but twigs left. Most of the leaves look nice and green and healthy. If it were my plant, I wouldn't be worried until it dropped alot more than that.

I agree. That could be the normal seasonal response. I wouldn't worry at this point.

Kudzu had given me some of his Moso that he started from seed in 2004. Mine are going great and they have been left outside throughout the winters. I usually move the planted up against the house on the back deck for just a little shelter from the weather. The Moso seems like a tough cookie in cold weather. My biggest concern is where to plant it in the yard....and when.

Make sure you give moso the best soil and drainage you can. Plant it in a south facing area. Moso is hard to get growing from a container plant. It will take 30-50 years to get a mature stand growing.

"It will take 30-50 years to get a mature stand growing".

Always lurking around and trying to remain silent, but I just can't buy that one. Have to say 10 to 14 years for in ground planting of Moso in the southeast U.S. to reach mature sizes.

My sentiments exactly Rogers sr. I thought they made a typo error and meant 3-5 years...

Well, a mature stand has culms 80ft to 85ft tall by 8" dia . Yes, you might want to talk to Chinese or Japanese experts about moso. they'll tell you the same thing.

They can't reach that here in the states! I did speak to Japanese experts when I was there a few years living.

I have been growing bamboo 20+ years and do not do much consulting with Japan anymore. However, one of our Moso groves produced several 6 inch diameter X 70 foot last Spring. That grove was 14 years old.

ABS list 7 inch X 75 foot for the mature estimate listed on edulis 'Moso'.

I would say you definately qualify as an expert Roger sr.

30 to 50 years!!!... mannn I'm digging mine up and tossing it over the fence...lol NOT!!!
