I've got a Dracaena plant; that has what appears to be white scale or something like it (see attached photos); I don't know much about plants, I bought this one in Vauxhall Flower market in London a year and a half ago, one month after it started showing these symptoms. I moved home and planned to buy new plants. I don't want the new plants to get infected with the disease, so I got the Baby Bio house plant insecticide spray - but the instructions are not clear about how to use it, and I'm not finding any instructions online, so hopefully I can find help here. My question is how to safely use Baby Gio house plant insecticide spray? I'm sure this is toxic and should use outdoors, but it's 2C ~ 8C at the time I wrote this post, and surely the plant is going to die if I leave it outside. So, what to do? How long should the plant stay outdoors until the spray effects finish? Any advice is appreciated! Even if that means throwing the plant away. Thank you!
