Growing grass in seven days is a daunting challenge. Taking into account various factors—such as soil condition and climate—can help maximize chances for success.
Start with quality seed. Select a variety that’s suitable for the growing season, climate, and expected mowing height.
Prepare the soil for planting by amending it with compost or other organic matter to increase water retention, drainage, aeration, and nutrient base.
Next, remove weeds, large rocks, and debris that could interfere with seedling growth. With soils such as clay, it’s important to incorporate gypsum to break up compaction and improve air circulation.
Water thoroughly and evenly at intervals of consistently moist soil until germination takes place. Irregular watering can cause weak spots in the lawn later on due to inconsistent germination.
Mow your new grass when it reaches two to three inches long; mowing helps encourage root development for a healthy-looking turf since too much thatch can interfere with the growth rate.
After mowing twice, feed young grass seedlings every four weeks until fully established (about six months). Fertilization helps speed growth rate but is not necessary if frequently watered or naturally fed by rainwater runoff from yard coverings like wood chips or mulch material.
Finally, keep an eye on competing species of weeds like crabgrass which may try to overtake the grass plantings before they are firmly rooted in the soil bed – hand pulling them will help control their spread without over-herbicide usage, which can be harmful to sensitive eco-systems!
