|Most garden plants are happy in soils with a pH of 6.0 to about 7.2. If the pH of your soil is above that, amend the soil with organic matter. Peat or sphagnum peat moss are highly acidic and will lower soil pH more than other organic amendments. You can spread 4-5 inches of organic matter over the area, dig it in to a depth of 10-12 inches and then plant. Once the bed is planted, lay another 2-3 inches of organic matter over the bare soil between the plants to help suppress weeds and slow water evaporation. At the end of the season dig the organic matter into the soil and add a fresh layer. Repeat this process annually and you'll end up with rich garden loam - and a spectacular garden.
