Shopping List

Supplies You Will Need

1. SOIL TEST KIT
to test the pH level of the soil. Do-it-yourself soil kits are sold at garden shops and hardware stores for less than $15, or for about $10 more you can contact your local extension service for a mail-in kit that takes about two weeks for results.

2. SAND
to mix with existing soil; about 3 cubic yards covers 1,000 square feet

3. COMPOST
to condition soil before seeding; you’ll need 3 cubic yards per 1,000 square feet

4. PULVERIZED LIME, peat moss, or sulfur
to correct the pH of soil; you’ll need lime if your soil is acidic, peat moss if it’s slightly alkaline, and sulfur if it’s very alkaline.

5. STARTER FERTILIZER
use a 12-25-12 mix; the numbers refer to the ratio of nitrogen to phosphorus to potassium. You’ll need about 5 pounds per 1,000 square feet.

6. GRASS SEED
about 4 pounds of seed per 1,000 square feet

1. Test the soil pH

Put measured amounts of soil and water into the test kit's plastic test chamber and shake well. Wait a minute or two for the soil to settle and the color to develop.

Hold up the vial and compare the color of the soil solution to the color-coded chart printed beside the test chamber. It should read between 6.0 and 7.5.

If the reading shows a pH lower than 6.0, your soil is too acidic and you'll need to add lime in Step 4. If it's above 7.5, the soil is too alkaline. For moderately alkaline soil add peat moss in Step 4; for very alkaline soil, use sulfur.
