| I recently purchased a home, the lawn is Korean Grass. In the last month or so large brown spots, 4-12 inch diameter, started appearing in the lawn. I have been told that I am watering too much and that I am not watering enough. How much water is correct for this type of lawn. This is my first experience with this type of grass, any help will be greatly appreciated. |
| Zoysia japonica is sometimes called 'Korean turfgrass'. It's a drought-tolerant grass that is slow growing, spreading by both stolons and rhizomes. Zoysia will get by on one-inch of water per week. The roots will deeply penetrate the soil in search of moisture, so be sure to water thoroughly but infrequently. Depending upon your soil type you should be able to keep your lawn looking its best by watering only once or twice a week during the summer months. To help you figure out how much water you're applying, put two or three empty tuna or cat food cans on the lawn and turn your sprinkler on. Time for 15 minutes and then check the level of water in the cans. When you've applied a full inch of water, write the time down. That's how long you'll have to run your sprinkler to give your lawn its full one inch of water. If you have sandy soil, apply one-half inch of water each time you water, and plan to water every 3 days. If your soil has more clay than sand, it will retain the moisture longer and you won't have to water as often. Hope this helps clear the confusion! |
