[{"question":"What is Kentucky bluegrass and why is it the most popular lawn grass?","answer":"Kentucky bluegrass (Poa pratensis) is a cool-season perennial grass that forms dense, dark green turf through its aggressive rhizome system—underground stems that spread horizontally and produce new shoots. This rhizomatous growth gives Kentucky bluegrass its signature ability to self-repair damaged areas, filling bare spots without overseeding. No other common lawn grass matches bluegrass for density, color, and self-healing ability, which is why it dominates premium lawns across USDA zones 3-7."},{"question":"What is Full Moon Kentucky bluegrass?","answer":"Full Moon is a premium Kentucky bluegrass cultivar known for its dark green color, excellent density, strong disease resistance, and aggressive rhizome production. It consistently ranks among the top-performing bluegrass varieties in National Turfgrass Evaluation Program (NTEP) trials. Full Moon establishes more quickly than many bluegrass varieties while maintaining the fine texture and deep color that premium lawns demand. It is particularly well-suited for USDA zones 3-7 in full sun to moderate shade conditions."},{"question":"What is the difference between Shamrock and Navy Kentucky bluegrass?","answer":"Shamrock Kentucky bluegrass is selected for improved shade tolerance and disease resistance, making it a strong choice for lawns with 4-6 hours of sun and moderate tree cover. Navy Kentucky bluegrass emphasizes aggressive lateral spread and wear tolerance, performing well in high-traffic areas and sports turf applications. Both are named, improved cultivars that significantly outperform common or VNS (Variety Not Stated) Kentucky bluegrass in color, density, and disease resistance."},{"question":"How long does Kentucky bluegrass take to germinate?","answer":"Kentucky bluegrass germinates in 14-28 days—the slowest of all common lawn grasses. This slow germination is normal and not a sign of seed failure. Soil temperature must reach 50-65°F for germination to begin. During the 2-4 week germination period, keep the seedbed consistently moist (light watering 2-3 times daily). Higher-grade seed (98/85 or better) germinates more uniformly than economy grades. Full lawn establishment from Kentucky bluegrass takes 12-18 months as rhizomes gradually fill the stand."},{"question":"What does 98/85 and 85/80 mean on Kentucky bluegrass seed labels?","answer":"These numbers represent purity/germination percentages. 98/85 means 98% pure seed (only 2% inert matter, weed seed, or other crop) with 85% germination rate (85 of 100 seeds produce viable seedlings). 85/80 means 85% purity and 80% germination—a lower grade with more inert material and fewer viable seeds per pound. Higher grades cost more but produce denser, more uniform stands with fewer weed contaminants. For premium lawns, 98/85 or higher is recommended."},{"question":"How much sun does Kentucky bluegrass need?","answer":"Kentucky bluegrass requires minimum 4-6 hours of direct sunlight daily for healthy growth. In less than 4 hours of sun, bluegrass thins progressively, becomes susceptible to disease, and eventually fails. Improved shade-tolerant varieties like Shamrock extend performance to the lower end (4 hours), but no Kentucky bluegrass thrives in heavy shade. For lawns with less than 4 hours of direct sun, fine fescue blends (like the Wicked Tuff Turf Sun & Shade Mix) are a better choice."},{"question":"When is the best time to plant Kentucky bluegrass seed?","answer":"Plant Kentucky bluegrass in late summer to early fall (August 15-September 30 in zones 4-6) for best results. Fall planting provides warm soil for germination, reduced weed competition, and a full fall growing season for root establishment before winter. Spring planting (April-May) is possible but less ideal—summer heat stress arrives before bluegrass is fully established. Avoid planting after October 15 in zones 4-5 because bluegrass needs 6-8 weeks of growth before winter dormancy."}]
