Frequently Asked Questions
When is the best time to plant heat-tolerant grass seed?
Plant your seeds when soil temperatures consistently reach 70 to 80 degrees Fahrenheit. This usually falls in late spring or early summer for most regions. Timing is everything, as late autumn planting often leads to poor survival rates for these warmth-loving species.
How much water does new grass seed need?
Keep the soil surface consistently moist until the seeds sprout. This requires light, frequent watering sessions rather than one deep soak. Once the grass reaches two inches in height, you can gradually transition to deeper, less frequent watering to encourage root growth.
Should I use a starter fertilizer?
Use a phosphorus-rich starter fertilizer to boost root development during the initial growth phase. Apply it at the time of seeding or shortly after. This provides the essential nutrients needed to help delicate seedlings survive the high-heat environment.
Can I overseed an existing lawn?
You can absolutely overseed to thicken up thin or patchy areas. Mow your existing grass short and remove debris before spreading the new seed to ensure good soil-to-seed contact. Aerating the soil beforehand significantly increases your success rate.
How long until I can walk on the new grass?
Avoid foot traffic until the grass is at least three inches tall and has been mowed at least once. Walking on young shoots can crush fragile roots and stunt growth. Give your new lawn a few weeks of undisturbed time to mature before hosting any backyard activities.
