The Q&A Archives: Mondo Grass

Question: Hi, I'm Arnold from the Beach Tower. We have mondo grass in our property. Does mondo grass needs a lot of water? Watering is set to 2 minutes every night. How do I get rid of those unwanted grass?

Answer: Mondo grass spreads by underground rhizomes so keeping the soil moist will help the plants grow and spread. As for weeds, I'd suggest hand pulling the existing weeds and then applying a pre-emergent herbicide to keep new weeds from sprouting up. Unless you are growing the dwarf or semi-dwarf types of Mondo grass, you may be able to use a product called Image. Be sure to read and follow label directions.
