Improve soil moisture by adding well-rotted organic matter

The single best practice gardeners can do to improve their soil is add organic matter. It has a profound effect on the physical and chemical properties of the soil and increases the water- and nutrient-holding capacity. It helps make nutrients available for plant use. And, as it accumulates, it binds clay particles into larger aggregates, improving aeration and drainage. Gardeners can reap the benefits of organic matter by regularly incorporating compost, manure and other organic residues into the soil before planting out or when dividing. It is better to only mulch (a top dressing to avoid damaging roots) around already established plants.
