A lot of lawns have weathered blistering heat and devastating drought this summer and look worse for the wear. September and October are the key times to sow new grass seed to make repairs.
Bare patches in the lawn or sections of dead grass need to be repaired to avoid opportunistic weeds that will take root in the soil. Weak or dead grass also is an open invitation to insects or disease. Late summer and early fall are the best times to sow grass seed because temperatures usually are more moderate and the soil is more evenly moist.
- Remove the dead grass, exposing the soil. Rough up the soil with a garden rake. Poor preparation of the soil will greatly diminish seed germination.
- The most common mistake people make when they buy grass seed is selecting according to price rather than quality.
- Another common mistake is allowing the newly planted area to get dry, which will kill the seedlings. Water newly seeded areas as needed so that the top two inches are kept moist. Once the grass gets about 2 inches tall, you can start to cut back on watering.
- Mow when the new grass is about 4 inches tall, removing only the top inch. A common mistake in mowing the lawn is cutting it too short. After the grass has been mowed once, apply a fall fertilizer. Grass should be kept at the 3 to 4-inch height.
