|Okra growing around two swales--the far swale is receiving a good |
dose of rain barrel water.
First step in building the mound is to put down a good layer of leaves or other water retaining material, because we have sandy soil. I use compost to form the rest of the mound. I also add kitchen scraps three or four inches under the soil in middle of the swale to add all those micronutrients. I mulch everything with pine needles to keep down the weeds.
The swale arrangement does a good job of capturing rainfall or irrigation water, because the water does not leave the mound. Also, there are fewer problems with weeds outside of the swale areas, because it is drier.
