need help with lawn drainage issue
Comments (2)Put in a dry well to intercept the runnoff then pipe it to the lowest spot in the yard. A trencher costs about a $100 bucks a half day and will make quick work of the digging the trench. Then go back and using a string line backfill the ditch to get the proper finish slope for the pipe. Once you have got the bottom of the ditch leveled out lay your pipe out, stick it together, tape your joints and kick it in the hole. I love watching geysers of storm water shooting out of a well designed drainage system during a hard rain....See MoreNeed help on determing issue - my lawn is beinng ruined
Comments (11)One of the frustrating things about lawns and water is that sometimes a lawn that looks like it is dying because it doesn't have enough water may be dying because it is drowning. I think there's a good chance that your problem is due to too much water. I live in the desert and I watered for the first time yesterday. We did have almost three inches of rain in June this year, but it sounds like you've had lots of rain, also. The areas that are affected may have poorer drainage or may be a little lower so that water sits there longer or they may just have some grass that is more susceptible to fungus. Don't water until the grass starts to get stressed, then water deeply. You need to let the soil dry out down to about 4 inches or so. If you can't tell by the grass, use a screwdriver and poke it into the ground to see how deep it's moist. I'm pretty sure at least one of those pictures shows some KBG, so if those areas have died, there's enough grass around them that is still green to fill in. I would not fertilize now, except maybe with a slow release fertilizer. Most organic fertilizers are slow release and there are some synthetic products that are also slow release. I don't have a lot of direct experience with fungus (it's just not a problem when the relative humidity usually hovers around 5%). I've read posts from others who have used cornmeal at 10-20 lbs per 1000 sq ft and had good results from it. That would also qualify as a slow release mild fertilizer. There are also synthetic anti fungal products available. I think the synthetic products are faster working. One important point is that you should not mix the two approaches. The cornmeal works by encouraging the growth of beneficial fungi, so if you use an anti-fungal application of some sort, the cornmeal won't work....See MoreNeed help with the lawn issue
Comments (8)Picture 1 looks to me like Black Medic which many people confuse with clover. Difficult to control even with "weed" poisons. Picture 2 looks like a thistle, as in Canadian Thistle. Picture 3 is difficult to identify. As a rule "weeds" get established and grow when the turf grass is not and that is often because of a soil related problem. The soil may not have enough available nutrients to feed the grass. There may not be enough soil moisture to support the grass for a number of reasons, but if that lack of soil moisture is the result of drought there may not be anything you can do, at this time. These simple soils tests can help you understand more about your soil and what you could do to make that soil a better place for grasses to grow with less of a "weed" problem. 1) Soil test for organic matter. From that soil sample put enough of the rest to make a 4 inch level in a clear 1 quart jar, with a tight fitting lid. Fill that jar with water and replace the lid, tightly. Shake the jar vigorously and then let it stand for 24 hours. Your soil will settle out according to soil particle size and weight. For example, a good loam will have about 1-3/4 inch (about 45%) of sand on the bottom. about 1 inch (about 25%) of silt next, about 1 inch (25%) of clay above that, and about 1/4 inch (about 5%) of organic matter on the top. 2) Drainage. Dig a hole 1 foot square and 1 foot deep and fill that with water. After that water drains away refill the hole with more water and time how long it takes that to drain away. Anything less than 2 hours and your soil drains� too quickly and needs more organic matter to slow that drainage down. Anything over 6 hours and the soil drains too slowly and needs lots of organic matter to speed it up. 3) Tilth. Take a handful of your slightly damp soil and squeeze it tightly. When the pressure is released the soil should hold together in that clump, but when poked with a finger that clump should fall apart. 4) Smell. What does your soil smell like? A pleasant, rich earthy odor? Putrid, offensive, repugnant odor? The more organic matter in your soil the more active the soil bacteria will be and the nicer your soil will smell. 5) Life. How many earthworms per shovel full were there? 5 or more indicates a pretty healthy soil. Fewer than 5, according to the Natural Resources Conservation Service, indicates a soil that is not healthy....See MoreNeed help diagnosing lawn issue!
Comments (4)Thank you for doing some reading. You don't really need a diagnosis before using corn meal. It doubles as an organic fertilizer as well as eradicating most lawn diseases. Since it stopped raining for a week I put some down today. So your lawn service treated for grubs multiple times already? I think I know the answer to this but did they look for grubs before treating? They're easy to find. You dig up a square foot of turf and if you find fewer than a dozen grubs, you cover it back up and leave everything alone. If you find a slimy, uncountable mess of grubs, then you can take action. But you might wait another couple weeks to go looking for them. This time of year they would still be eggs. Then you would expect to see damaged turf in August or September, not May and June. You may need to adjust your sprinklers, too. If you are watering more frequently than once every 5 days (in 100 degree heat), then that is too frequently. Grass should be watered deeply and infrequently. I have yet to water my lawn either in San Antonio or in the Hill Country. Deeply means 1 inch all at one time. Infrequently means once per week with temps in the 90s, once every 2 weeks with temps in the 80s, once every 3 weeks with temps in the 70s, and once a month the rest of the cooler part of the year. With temps in the 100s you should be able to go once every 5 days. When you allow the soil surface to completely dry out you avoid disease and weeds in St Augustine. Lawn care is as simple as watering (described above), mulch mowing at the highest setting (always for St Augustine), and fertilizing 3x per year. If you are doing those three things you should not need any other treatments like insecticide, herbicide, fungicide, dethatching, core aerating, top dressing, or composting. Once you eliminate the need for the counter measures, it's dead simple....See Morecramol
