Many factors affect germination. Cool weather delays sprouting, lack of moisture will prevent sprouting, and over-watering and high temperature can induce disease. Proper care and maintenance are essential to the establishment of a healthy lawn. Your lawn will germinate, mature and become established over an eight week period. Here is an idea of how a lawn should progress:

First and second weeksa few seedlings (mostly ryegrass) begin to appear.
Third and fourth weeksbluegrasses germinate and begin to grow.
Fifth and sixth weeksall grasses should have germinated and begun to thicken.
Seventh and eighth weeksgrasses fill in and are established.

Watering is a key factor in establishing your lawn. The seeded area should be kept moist but not wet. Water the area until a slight puddling occurs. This will help develop a deep strong root system. Watering frequency should be systematically reduced over several weeks time so the roots can strengthenand adapt to more normal conditions. A good rule of thumb is one inch of water per week. Frequency also depends on the weather, soil type, seed type and rainfall. Be cautious not to over-water your lawn (large puddles in the lawn,) or under-water (dried out, cracking, and brown turf.)

As your lawn fills in and becomes established, it will need regular care. When the grass is about 2” tall, begin to mow weekly. Raise mower to standard cutting height when lawn is established. 2.5” is a good height during spring and fall. 3” is best in the hot summer months. Weed control is best achieved with a combination of herbicides and hand removal. Fertilization can take place after the first cutting at one half the manufacturer’s suggested rate for established turf. The following year you may fertilize at the recommended rate.
