do they wipe off??

are you spraying the plant ...

Yeah, wiping off is my first question, too. Lucky bamboo can sometimes weep a little bit if overwatered, particularly in late winter, early spring as growth resumes. Check closely for insects or other pests, but if you don't see any, wipe away that bit of mess and see what happens.

Think of it as the sap rising as the season turns. :-) It's not, but it's sort of comparable.

I wipe off too many times, but than same happened. I have my lucky bamboo about 3 month and it has this problem 3 month. I checked other plants, its far from my lucky bamboo, and they dont have problems

Might be Mealy Bugs. Try insectacial soap spray. I am experimenting with using cheap mouth wash sprayed on the bugs- so far the results are fair, it is a non toxic solution. Keep plant as isolated as possible and check it daily till it is bug free for 2 weeks at least. Mealies can also be treated by dabing them with alcohol on a Q-tip. They can also me manually smushed with your finger, or a flat tooth pick for tight areas.

There is also a Lucky Bamboo Forum on this site.
