Ugh! I bought this plant from a fb seller several weeks ago; noticed fungal gnats in and around it, so decided to re-pot. The roots are all rotted, every single one is squishy, I don’t see anything viable here. What can I do??? Really frustrated, bought 2 orchids from him, just discovered that the venda has fusarium, had to throw it away. So, is there a way to save this plant?
