Real plants have something white on them,need home remedy

true Bayer aspirin mixed and dissolve well in water. water lightly 2 or 3 times.... don't drench them though...

You don't say if this is indoor or out but, on indoor plalnts, if it is something that looks like tiny bits of cotton, it is probably mealy bugs and depending on the size of the plant, with a Q-tip wet with rubbing alcohol, you can remove them - just wipe it over them and they will turn brown. You'll need to do this daily until the infestation is gone. If they are outside plants, they can also get mealy bugs and there may be something you can buy specifically for outdoors.

Mealy bugs?? I kill them with Q Tips and Nailvarnish remover.

If it's mealy bugs, alcohol should kill them. You can also try handpicking them off if that's not too tedious.

Could be a number of reasons.Indoor or outdoor,a photo would help to determine the correct answer
