Hi, brown spots have started showing near the roots of my Areca palm. Does anyone know what they might be?
I water it once a week (0.5l, 17oz), it's been in the same pot and soil for 5 years, since I bought it from Ikea. I haven't done anything to the soil and I haven't moved it around, it's right next to a window and it's recently gotten warmer here in Switzerland.
Thank you
