Drooping Leaves Indoors?

[Matt in TN]

I'm probably over-thinking this, but the moso I've brought in for the winter has changed from mostly upright to looking fairly "droopy" and laying down. Is this a sign of too much/not enough water, humidity, sunlight, or something else? Or is it just feeling like the winter has dragged on and is ready for spring (like I am!)?

It has 11hrs of grow-bulb light every day, and I started out misting it daily and watering it weekly. Once it started drooping I thought maybe it was being over-watered, stopped misting it, and cut back on the watering.

Any ideas?

My guess, and I stress guess, is that you brought in a culm that had not fully hardened and is now drooping due to reduction in sunlight. Gently squeeze it and see if it feels like you could easily snap it.

I have been watering mine ever two week. I have had my wood stove going quiet a bit lately with all the extra cold and then ice & no electric. They seem to be doing good. Starting to grow.

I would also increase the amount of time the growlights are on, probably in the 14-16 hour range. That way you can make up for the decrease light levels.

I also have Moso inside for the Winter.

It's definitely the light level since mine are doing the same thing. I can't wait until I can get these guys outside again under full sun where the leaves can harden back up.

3ft and still growing.

That was it - I increased the light from 11hrs to 14hrs and it started to perk up a little in the first day. I'll bump it up to 16 or 17 hrs and see if it'll help more.

BTW - this is a single 60 watt grow light about 3 ft over the plant, in addition to regular room light.

Thanks!

You may also want to try moving the light closer to the plant. The instructions for your specific grow light may provide suggestions, but closer means much more intensity, as long as it's not too hot.

Now that daylight is starting to increase and the outdoor bamboos have had more than enough of a dormancy season, I decided to try bringing in one of the weaker mosos inside by a south facing window. The objective is to see if this one will end up ahead of the ones that are left outdoors/greenhouse by around May after the outdoor ones have gone through a shooting cycle too.

Since this one has received 3 months of dormancy already and gets an entire south facing window for itself, I'm predicting that the shoots that come up in 1-2 weeks will be fairly strong and capable of adjusting to outdoor conditions when I take it back outside in about 2 months or later. I think spring daylight through a window should be enough to get this guy growing very well. I chose the middle of January also because that will allow it to have ample time to shoot, leaf out and be primed to shoot again by spring. I don't expect it to look anything like the plant I had in the other picture with very etoliated culms and droopy leaves.

It looks exactly the same as when it was placed in the greenhouse 3 months ago and it takes about 1 week to bring it out of dormancy.

how can you say that ?
thanks for let us know when it going on .



I live in zone 9, I have got a small pubescens bicolor in pot but it s not very heallty at all for the moment. a small shoot has appeared last week but it s not growing much because a bit too cold outside at the moment,
do you think I should keep it outside or I can put it inside to make this shoot grows quicker ?
thanks

Philippe, I say outdoors is better, I do not like my bamboo to shoot indoors those shoots always produce weak culms and I think it is wasteful to the plant.

Not unless you can provide it a lot of light and being in zone 9, it might be better to let it stay adapted to outdoor conditions. In most cases bamboos may have a hard time adapting back to the outdoor conditions due to an abrupt temperature change along with increases sunlight.

I have lots of these small mosos so I have the freedom to experiment with them as much as I want. I've killed off a few by leaving them in pots outside, not buried which died off, and the ones that were buried mostly top-killed, but came back. The tarped + buried ones kept foliage, as well as the ones kept in a greenhouse. The ones kept indoors last year kept shooting over the winter and had a hard time adjusting to outdoor conditions, but still made shoots by May and caught up to the outdoor ones.

This particular moso gets a 30X30'' south facing window all for itself and it has remained dormant for a long time so I'm letting it get a running start into 2011 to see if it beats out the rest. Hopefully the stronger sun will cause it to produce stronger culms that adapt well to outdoor conditions. BTW, do you have any pictures of the little bicolor?

I thought the same , it s better to leave it outside

I ll take a picture of it one and post it one of these days ,this picture is interesting, the original culms within any leaves anymore, one shoot from october that has stopped growing but still very green and a new shoot from january growing very slowly

steve, thank you for your answer

I had two bigger culms in that pot but they have lost all their leaves and they are very dry, I think they are gonna die

at the moment, I try to water less than once a week.

I hope to get stronger shoots at the end of march.
