Clover seeds are very small and lightweight. To ensure they spread evenly, it's best to mix them with another medium that will make them easier to distribute on the ground. You will need about 2 oz. (57 grams) of seed to cover 1000 square feet (93 sq. m.) of lawn. Before planting, mix your seeds with one of the following:  Soil (preferably unfertilized, to discourage the growth of weeds) Sand Sawdust Use your hand to spread the seed evenly over the lawn. If you have a large lawn, you can use a broadcast spreader, which you can buy at local garden stores and home improvement stores. You can also spread seed over large areas by smoothing the seed and sand mixture over the ground with a leaf rake turned so that the tines face up. Clover seeds will not grow if they are buried in the ground, but covering them with a thin layer of soil will help to keep them in place and prevent wind or predators from disturbing them. Go over the area you've seeded with a rake that is turned so that the tines face up, and gently mix the seeds into the top layer of soil. Do not rake more than a quarter-inch (6 mm) deep, otherwise the seeds won't grow. Water the seeds immediately after spreading them. This process will help the seeds stick in the ground and encourage germination. Provide the seeds with a light misting of water every day that it doesn't rain until the seedlings grow leaves.  During the spring, summer, and warmer fall months, make sure the clover gets about 1.5 to 2 inches (3.8 to 5 cm) of water per week. When planted during the warmer spring or summer months, clover seeds will germinate in one to two weeks. Make sure that the seeds do not have a chance to dry out during the day, or the sprouts will not survive. Once your clover lawn is established, take soil samples at least every 2-3 years. Check your soil nutrient and mineral levels, and make adjustments as needed. Try taking samples in spring one year, and in fall the next year. This will help give you an idea of which nutrients are most needed during different parts of the growing cycle.
Mix the seed with sand. Spread the seed. Rake the area. Keep the seeds moist until the clover is established. Test your soil occasionally after your lawn is planted.
