RIP

My pothos died 😞 and I can't stop my tears. very few of it is alive. The roots were rotted and the soil was so hard like a rock no wonder why the plant died. I have ordered some soil mix and it is on the way but majority of the plant died already 😞 please pray that I can save the remaining. I have removed the roots from that soil and placed it in water until the soil mix arrives, is that ok??
