Step 1: Gather seed, fertilizer, and compost to bring dead patches back to life. Patches of your lawn can turn brown for various reasons. They are most often caused by too much traffic, the roots compacting, too much fertilizer, not enough water or insects and animals that dig up the lawn.
Step 2: Prepare a large patch of seed mix for multiple problem spots If there are numerous areas on your lawn that need attention, mix a large batch of compost, seed and fertilizer in a bucket. This will save time. Be sure to follow step #3 to prepare the soil and step #5 after the mixture has been applied.
Step 4: Apply fertilizer, seed and compost Following the manufacturer's directions for new seeding, lightly sprinkle fertilizer on the area and work it into the soil with the cultivator. Sprinkle the new grass seed as you would sugar on pancakes. Cover the seed with compost, and step on the patch to set the seed.

Step 5: Add lime to reduce acidity. If you think your dog may be part of the problem, you may need to add lime to neutralize acidity from urine. Use a PH test kit to determine the level on your lawn. Grass prefers a level of 6 to 7. If lower than 6, add a little lime.
