hello, this yucca is indoor, now it's winter here how should i understand these yellowish patches? too much water, too less, it's normal during winter or problem is something else?
I'd suggest just watching this to see if it progresses. From my expoerience with Y.guatemalensis (aka Y.elephantipes) is any help yours seems to either gotten a bit too much sun or was too cold at some point. http://growingontheedge.net/viewtopic.php?f=2&t=7597&view=print
thanks for your answer i checked the link you gave... when it comes to "too cold" they are talking about below zero celsius, in my room even if i open windows it never falls under 15 degree celsius. sun burn - it cold be but again i find it strange because i had it whole summer and nothing has happened and now it got sun burn during winter? windows are facing south-east and there's tall building just across so it gets (winter) sun from 8 to 12 o'clock . could it really be the reason?
I've had plants outdoors sunburn in Spring after all winter in the sun. So I wouldn't rule out anything. Someone else may have another idea.
