My lawn is a swamp in winter, any suggestions?

I had the same problem on the side of my house. I installed french drains. But I have a tiny piece of property so it wasn't too expensive. A few hundred dollars at most.

Another option would be to bring in more dirt to raise the level of the lawns, and reseed. This may have to be done over time too, as the new soil will compact some after each storm.

Do you live near wetlands? Do you live near a natural spring? I would find out what's causing the continuous water source before I spent any money trying to fix it. After you find the water's source, then you'll have a better idea of how to deal with it. If it's something you can fix with new soil, absolutely get (or borrow) a tamper (This is a tool for tamping earth. It has a heavy cast concrete head with a flat bottom. You pound the earth with it to compact the dirt. It is a tool that might be used in road work, or for preparing ground prior to pouring a cement floor, etc.) It's a lot of work, but IF adding new soil will work, it'll be worth it. Good luck Kay

You might also have a problem with to compacted soil if this is the case you are going to have the soil aerated to allow drainage of water. or you are going to have to add soil to eliminate low spots from collecting water I lived xt to a lower vacant lot that the builder decided to develop he brought in truck loads of soil the ran it over with a steam roller he compacted the earth so much that water could not absorb into the soil it had to be aerated with a large machine to allow for drainage

If you have access to a very large rock pile I would dig trenches were you walk and fill in with rocks and put the soil were you want to plant this should raise you soil and have a nice walk way its a lot of work but cheap as the rocks are free???
