Hello guys, My polka dot begonia that i bought a couple of weeks ago isnât doing well. I water it regularly, and it's next to the window. But it has been freezing in Vancouver around -10 lately, so my house temp is around 21 and maybe even colder next to the window, and itâs been really gloomy. The leaves are getting dry, and theyâre losing their colours. Is there a way I can save this plant? What should I do? Thank you!
