I put my basjoos in my greenhouse where at nights it gets around if not just under 50 degrees. Through the day it's between 70-100 degrees. Is it from the temp change or did I water to much?? I'm not sure how to post a pic but I do have one..
Any Idea????

most likely to be over watering,make sure perlite is mixed in to any compost for good drainage,very important especially in winter months.

Watch for spider mites with those temps. You may be better off moving it outside during the day.

You do want to get the temp fluctuation under control somewhat. from 50 at night to 100 during the day is too much. 30 degrees or so variance is ok, but 50 is too much for most things. You need ventilation and/or shade cloth. Most likely the basjoo isn't the only thing that won't like that kind of fluctuation, most of your stuff will be unhappy...
You didn't say whether you just moved potted basjoo from outdoors to in, or whether you dug them up recently. If you just dug them up and potted them, then that would be perfectly normal due to the root disturbance and issues like temp change. They will also most likely lose several leaves.
If they were already potted, then it's also due to adjustment, but you do want to make sure your watering is enough, and yet not too much, since they are going to be actively growing at those temps still. They will not be growing as fast as they were during the summer, and they are getting shortened day length too which causes them to yellow. You're not getting it quite as bad down in N. Alabama as we get it in Indiana, but your days are shorter too, which automatically means less sun hours. They normally do show some yellowing this time of the year in my greenhouse too but they should snap out of it when they adjust. Also if they were already potted, and they will be still actively growing,use fertilizer on them, about 1/2 or 1/3 of what you were using in the summer. That's another reason to adjust your watering schedule, shortened day length means that they are not going to use as much water.

Sandy i think your right its from the huge difference in temps.. My cannas and ears are also showing some yellowing and those things cant get enough water.. I keep my space heater on all the time, but i think maybe i should shut it off on sunny days to keep it down.. I'll keep checking to keep in in a 30* range.. There were only a few days it got that hot in there but the sun was beating and the heat was on. I though it would be best to get it as hot as possible, but i guess i was wrong. I have a door i can open if it needs to be also..

Sunfish i wish moving them outside durning the day was an option for me but i;m 14 weeks pregnant and theres no way i can move them safely there about 24" diameter at the top of the pot. I'm the only on here through the day and my husband had trouble moving them front the front to the backyard just by dragging them, there very heavy..

No sign of spider mites, and yes they have been potted since i got them in july..

How's the humidity?

When I grew bananas in greenhouses, the only issues I had with temperature was dry heat. 50 at night and 100 during the day should be no problem if the plants are watered well with high humidity. I grew a basjoo in the ground inside my greenhouse. I would let it get up to 110F before the vents turned on. I was able to do this because I kept the humidity way up.

If I had the vents set to turn on at 95F, the humidity would go way down and the plants would suffer (even though the temp was lower). The plants did far better when I turned the vents off and kept the humidity high. 110F @ 90% > 95F @50%

ok i stand corrected!! i've got spider mites, seems like it happened over night but wow those things are every where, off to get spray...

Velutina

An easy option for controlling spider mites in a greenhouse is simply spray the underside of the leaves with the hose. I would turn the hose on barely, put my thumb over the end and get a nice fast spray. Bananas are simple cuz you can spray the underside of every leaf in a matter of minutes. This technique has never failed me.

i wiped them down with a dish soap soultion, i will keep them sprits with the hose for a few more days to keep them away, then i'll do it every few days after that.. I cut most of my other plants, most of my elephant ears i just chopped down to the stem, as they grow back so quick its just easier..

If it's warm enough during the day open up the greenhouse let some air in,helps some with the SM.

Since mine is just a cheap made PVC greenhouse Covered in vapor berrier the best venting I can do is open the door. We're just renting here and don't want to spend much on a greenhouse until we get settled in to our own house.
