1. Rough up the current ground cover. The roots from the sod need to make contact with dirt, so use a rototiller or similar tool to expose the soil beneath.
2. Add some lime. Lime promotes lawn health by providing nutrients and improving soil structure. Because lime is absorbed slowly, add it prior to the sod.
3. Fill in the gaps. After fitting the sod pieces closely together, cutting and trimming as needed, fill in the joints with a mixture of soil and grass seed.
4. Compact and water. Compact the sod using a roller—or by driving over the installation with a pickup truck! Water for 20 minutes in the early morning (before the sun gets too high) and 20 minutes in the evening (after the sun has set).
A month later, the sod we would have sent to some refuse center is living on and looking great. Both we and our neighbors couldn’t be happier about that.
