Gulf Muhly Grass Recently Planted In TX In Full Sun Light Planter Boxes. Why Has It Started Turning Brown? Is This A Bad Sign?

Question

I planted 7 Gulf/Pink Muhly grass plants in tall planter boxes in direct central texas sunlight. These have been planted for about a month now and are turning a light brown color and the green is going away. What is the cause of this? We try to water heavily but may miss a day or two throughout the week.

Answer 1

This sounds like it could be overwatering. They don't like to be wet, and do need a dry out between waterings. I would wait until it is dry down to about 1/3 or 1/2 of the container. This article will give you some general care on the plant:
