Step 1: Prepare the Ground
If hand sowing, divide the site into 3-ft (1-m) squares with string or canes. Stir the seed to mix evenly. Weigh out seed for 1 sq yd (1 sq m), following the directions on the package. Pour into a plastic cup, mark the level, and use it as your measure. As a guide, 1 oz (30 g) is roughly a handful.
Step 2: Scatter Seeds Evenly
For even distribution, scatter half the seed over the square in one direction, and half at right angles to it. Use the same crisscross method if sowing by machine. Repeat for each square. When all the seed is sown, remove the strings or canes.
Step 3: Lightly Rake
Seedlings should appear within 14 days. Water regularly. Mow for the first time, on a high setting, when seedlings have reached 2 in (5 cm). For fall-sown lawns, maintain this height until growth slows. The following spring you can gradually lower the blade height.
Whether you are laying sod or sowing seeds, preparing the soil is key to successful grass growth.
