Lawn Irrigation questions, answered by experts

Properly secured bird netting is the best option to cover your grass seed with. It creates a minor moisture barrier that can help seeds sprout, and it’s a great way to keep birds away from your seeds. A cheaper, lower-maintenance option is hay or mulch, but these can change the look of your lawn and require cleanup in the case of straw.

While hydroseeding is typically meant for bare soil, it is possible to hydroseed over an existing lawn with some adjustments. For the new seed to germinate and thrive, it needs good seed-to-soil contact. Without it, most of the seed may not take root and will die. To improve your chances of success when repairing a patchy area, mow any existing grass as low as possible and loosen any exposed soil before application. It is also recommended to use a finer mulch mixture when spraying, as this will help the seeds reach the soil and root without suffocating the existing grass.

The best time to plant grass seed depends on your local climate and whether you have cool-season or warm-season grass.

For cool-season grasses (like tall fescue), the ideal time to seed is late summer or early fall (typically August and September). During this period, the soil is still warm from the summer, but the air is cooler, creating optimal conditions for germination and root establishment before winter. There is also less competition from weeds. Spring is a secondary option, but cooler soil temperatures, the risk of a late frost, and less time for the grass to mature before summer heat can make it less successful.

For warm-season grasses (like St. Augustine), the best time to plant is from late spring through mid-summer (typically May and June), when temperatures are consistently between 75 and 90 degrees Fahrenheit.

In general, it is best to avoid seeding during winter or early spring, as cold soil and air can prevent seeds from germinating. For recommendations tailored to your specific grass type and climate, consider consulting a local lawn care professional.

Fescue grass is a relatively low-maintenance grass type, meaning it doesn’t require much more attention than regular watering, dethatching, and mowing. Some fescues even grow slowly enough for hard-to-reach areas, particularly those inaccessible by the mower. Following a seasonal maintenance schedule will help your fescue lawn stay green, healthy, and durable for years to come.

Yes, but the best approach is to apply fertilizer well before you actually sprinkle the seeds. Apply fertilizer with an NPK ratio somewhere around 10-10-20, or 10-10-10, depending on soil test results and the type of grass you're planting, about six to eight weeks before planting grass seed. This mix added to loosened soil will give the grass seed its best chance of getting off to a solid start.
