Time Of Planting
I am considering planting dwarf mondo grass on a hill side near the house with only 6 hrs. of sunlight. I presently have periwinkle in the area but have problems with root and stem rot. Is mondo grass tolerant of root and stem rot, and when is the best time to transplant it?

Nothing is fully tolerant of root rot. This has more to do with the soil drainage and how much water the plant receives, as too much moisture normally leads to issues with root rot. Mondo grass can be planted in spring or fall and needs well-draining soil. If the area had issues with rotting previously, you may want to check its drainage prior to replanting anything else. Amenidng the soil with organic matter, like compost, can oftentimes help with drainage issues. Also, take note of drainage patterns and if there is significant pooling of water during rain or watering. If so, this needs to be addressed.
