mini: What I mean is that when it rains even alittle their are mud pits all over my yard and some places even turn into a mini swamp. The water isn't be soaked up by the ground. I've tried putting more grass seeds down thinking that more grass will hold the soil better but nothing. Can anyone help me out.How come every time it rains my yard becomes like a mini swamp?French drains would help your yard a lot. Just trenches (a few feet deep) filled with rock and covered over - will absorb quite a lot of water.|||Your yard, much like mine, needs to be leveled. Your yard should actually set at a slight grade sloping towards the nearest street or alleyway. This is so that run off can go to the storm drains easily. My yard puddles for the same reason. You can actuall make a small ditch to irrigate the area. You can have a french drain put in, or you can have your yard leveled.How come every time it rains my yard becomes like a mini swamp?It sounds like you have compacted clay-like soil. Not a nice sandy loam that would take well to lots of rain. You should aerate your lawn. Call some fertilizer companies to get some quotes. They will want to know about how many square feet of lawn you need aerated. Or, if you have an equipment rental place near-by, you could rent one yourself & get the job done in an afternoon. Preferably not when the lawn is still saturated. Leave the plugs on the lawn.|||It depends on a few factors. What kind of soil do you have? Clay will drain the slowest. Is the water pooling in the same area all the time? Check the grade to where the excess water can run off. Do you have a yard next door that their runoff is running into your yard? Can that be diverted. Do you have a septic system or an old one that is full? This could cause flooding. You might want to check out a contractor that can give you an idea of what the cause or causes are. Check with a few of them for an educated decision.How come every time it rains my yard becomes like a mini swamp?The first problem is poor drainage and poor soil. The best way to solve the problem is to create positive drainage. If the elevation of your house foundation is high enough, you ( or a landscape contractor) can pitch the lawn from the high point at the house to a lower elevation. This creates positive drainage. The soil can also be rototilled to mix with any new topcoating that may be brought in. You may have to have this new elevation done with a builders level if the existing grade is not workable. Finally, check with local laws governing water runoff from your property.
