The next morning, I see my Monstera was sunburned at many different locations. The ends and sides of the leaves turned brown, and there were some sketchy dark patches. I knew I had to do something to help my plant, so I followed these steps:

But hey, I didn’t give up on her. I went online and bought this cool GE Lighting 93101230 LED thingy. I hung it about 12 inches above my Monstera, and you know what?

Make sure your Monstera is getting enough water
