My Mini Mondo Is Turning Yellow Rapidly.
I have a massive area of mini mondo that is turning yellow rapidly. It have been beautiful, lush and thick for 10 years. Would it be Pythium Root Rot? If so, is this treatable or should I remove and start again?

Unfortunately, your photo did not come through. Depending on how the damage looks, it could be quite a few different things.
If the plant has never been divided, then this is likely the cause of the plant's degrading health.
Over, or underwatering can cause similar symptoms.
If this is planted near sewage, or a septic line, then the system may have failed. Raw sewage is deadly to plants.
Nutrient deficiencies of many sorts can be to blame, if this area does not get fed at least once per year.
Dog or other animal urine can cause dead spots, as well.
