| Having covered many bare spots in my backyard with Marathon Sod II, the grass in my backyard grew only it grew thin and delicate. There is no brown-yellow spots in certain spots. What can I do to remove these spots? I have dwarf brand grass, I think it's called and I water everyday. |
| Marathon is a fescue type sod and is very well suited for your growing region. As long as you prepared the soil prior to seeding or sodding, it should grow well for you. I'm not sure why you are having problems in certain spots, but I do think you are watering too much. It is better for lawns to be watered deeply but less frequently than you are doing. Here are some guidelines: Good lawn care can be summarized in three cultural practices: mowing, watering and fertilizing. If you will do these three properly, your lawn will be the best on the block! Frequent mowing is better than infrequent mowing. Mow on a 5-7 day schedule, removing no more than 1/3 of the leaf blade with each mowing. While many homeowners like to water 15 minutes a day, your turf will benefit from a good soaking applied less often. Apply 1/2 to 1 inch of water once or twice a week. A coffee can makes a good rain gauge to test out how long it will need to be run to apply an inch. Frequent wetting promotes disease problems and a shallow rooted turf. Let the soil dry out a bit between waterings and the grass will develop a deep root system and do much better. Fertilize with no more than 1/2 to 1 pound of nitrogen in spring after you have mowed the grass twice, again in June, another feeding in September and again in late November. Apply a product with a 3-1-2 ratio of nutrients as this is roughly the ratio of nutrients grass takes in. So, for example, if you purchased a 15-5-10 fertilizer (15% nitrogen), you would apply about 7 pounds per 1000 square feet (1 pound / .15 = about 7). If you purchased a 21-7-14 fertilizer (21 % nitrogen), you would apply about 5 pounds per 1000 square feet (1 pound / .21 = about 5). Healthy turf will choke out most of its weed problems. When the turf is thin and soil is exposed to the sunlight, weeds will sprout and you have a battle on your hands. So first concentrate on the above 3 cultural practices and you will be amazed at the results. |
