very small wet lawn drainage

Hi folks, have a very small (2m x 4m) patch of grass in my tiny garden.

I started the garden from scratch when i moved in but the soil was very full of clay. I did my best to remove clay and add better soil but my lawn gets very very wet and doesnt dry out well.

Any ideas or tips would be very much appreciated!

Thank you

I just posted tis under in a similar topic.


From the sound of it you will want to put in a french drain. A french drain is a pipe burried in the ground with holes in it to let the water in, the pipe should be covered with a special cover to keep the dirt out of it, and then be surrounded by gravel. It should be about 6 inches or so deep. You will need to run it down hill to a spot where the water can drain out, or build a dry well. You can get the pipe and covering at your local hardware store, it is not that expensive, the digging and bringing in gravel is the hardest part.

As the soil is clay you may also amend the soil by adding compost and round sand, if you add sand it must be the round kind as the sharp kind will turn the clay into rock, you need to add lots of it as well.

Any soil can be made to be productive with time and amendment. If you regularly top-dress the lawn with good quality compost, over time, this compost will work it's way into the clay soil. To speed the process, CORE aerate the lawn prior to top-dressing. This will allow the top-dressing to drop down into the cores and will do a wonderful job of amending things.

As the previous poster indicated, round sand can also be used in this manner and will loosen things up, but doesn't add much in the way of organic matter. A combination of the two could also be used.

I still suggest that aeration should be done prior to the top-dressing, though, to speed the process of penetrating your clay soil profile.
