The best way to water a garden on sloped ground involves slowing water down before gravity turns it into a tiny downhill river. Drip irrigation, terracing, contour planting and careful watering habits can help moisture reach plant roots instead of racing across the soil and carrying precious topsoil with it.
A flat garden gives water a fairly simple job. A sloped garden adds gravity to the conversation, and gravity has never been known for patience. Pour on too much water too quickly, and the upper part of the garden may stay dry while the lower section becomes soggy, muddy and mysteriously talented at collecting every bit of soil that once lived uphill.
