Frequently Asked Questions
-
How long does it take for the seed to germinate?
Germination typically occurs within 7-14 days under optimal conditions with consistent moisture and temperatures between 60-75°F.
-
What is the best time of year to plant this grass seed?
The ideal planting times are early fall (late August to mid-October) or spring (mid-April to early June) when soil temperatures are favorable for germination.
-
What do the numbers on the seed tag mean?
The seed tag shows purity percentage (amount of pure seed), germination rate (percentage that will sprout), weed seed content, and other crop or inert matter. Higher purity and germination percentages indicate better quality seed.
-
What is the recommended seeding rate per 1,000 square feet?
For new lawns, apply 3-4 pounds per 1,000 square feet. For overseeding existing lawns, use 2-3 pounds per 1,000 square feet.
-
Is it better to use a single species or a seed mix?
A single species like Kentucky Bluegrass provides uniformity in color and texture, while a mix offers better disease resistance and adaptability to varying conditions. Your choice depends on your priorities for appearance versus resilience.
