The ever-dying begonia Iâve been ready to yeet this plant out the window for like 2 months. Itâs looked like this since February and wonât improve no matter what I do. Iâve repotted into fresh mix, treated for pests, adjusted watering schedule, and moved it all around the house to see if changing up the lighting helps. Whatâs her problem? đ©

Tips needed Found this cutie in a large pile of sad looking plants at Walmart. I could have picked out a bunch more. Some looked much better. Might go back tomorrow. Anyway, this plant type is new to me. I put it in my bathroom on a shelf next to a south window. Replanted it also. Any tips are appreciated. #Begonia #PolkaDotBegonia #NewPlants #PlantsMakePeopleHappy #PlantAddict #HappyPlants #PlantTherapy

My âPink Spotâ begonia has been a major work in progress since I got her in August 2025. She was jostled a bit on her way to PlantCon, so I got her for a steal of $5. Then I struggled with getting her conditions right for *months*. She lost so many leaves in that process, but just look at her now (top in pic). Sheâs finally thriving! Now Iâm hoping sheâll get more pink in her leaves. Iâm glad I didnât give up on her #Begonia #PinkSpotBegonia
