Lawn Fertilization Frequently Asked Questions

• When should I fertilize my lawn?

  The best time to fertilize depends on your grass type. For cool-season grasses (fescue, bluegrass, ryegrass), fall is the primary season. We apply 70% of annual nitrogen between September and November. For warm-season grasses (Bermuda, Zoysia), fertilize during active growth from April through August. Virginia Green's agronomists time each of our 7–11 annual applications to your specific grass type and local conditions.

• How often does my lawn need fertilizing?

  Most lawns benefit from 5–7 fertilizer applications per year, spaced throughout the growing season. Virginia Green's Premium program includes 7 applications, while our Estate program provides 11 treatments including additional a maintenance application of lime, disease control, and grub prevention. Each application is timed to your lawn's specific needs rather than a generic calendar.

• What do the numbers on fertilizer mean (N-P-K)?

  The three numbers on a fertilizer bag represent the percentage of Nitrogen (N), Phosphorus (P), and Potassium (K) by weight. Nitrogen promotes leaf growth and green color. Phosphorus supports root development and is restricted in some states for maintenance applications. Potassium strengthens cell walls for disease and drought resistance. Virginia Green selects the right N-P-K ratio for each seasonal application.

• Is professional fertilization worth the cost vs. DIY?

  Professional lawn fertilization typically costs $350–$500 per year for 7 applications, while true DIY costs more when you factor in products, equipment, soil tests, and your time. With Virginia Green, you also get commercial-grade, slow-release products not available at retail, calibrated equipment for precise application, expert timing, and a 100% Satisfaction Guarantee.

• Is fertilizer safe for kids and pets?

  Virginia Green uses products that are safe for families and pets when applied correctly. We recommend staying off treated areas until the product has been watered in and the lawn is dry — typically 24–48 hours. Your technician will provide specific re-entry instructions after each application.

• Is fertilizer bad for the environment or the Chesapeake Bay?

  Improperly applied fertilizer can contribute to nutrient runoff and water pollution. That's why Virginia Green uses calibrated commercial equipment for precise application rates, slow-release formulations that reduce runoff risk, and state-certified applicators trained in environmental compliance. Fertilizer applications are made according to turf needs and state regulations. Professional application actually reduces environmental impact compared to typical DIY over-application.

• Why shouldn't I fertilize fescue in summer?

  Applying nitrogen to cool-season grasses like fescue during hot summers promotes fungal diseases like brown patch, increases the lawn's water demand during drought conditions, and can cause fertilizer burn on heat-stressed turf. Virginia Green monitors your lawn during summer but intentionally withholds heavy nitrogen to protect long-term turf health. Instead, we focus on weed control during this time of year to keep lawns free of weeds, and Estate Program Customers receive disease treatments to protect turf during heat stress.

• Do I need a soil test?

  Yes — a soil test is the foundation of effective fertilization. It reveals your soil's pH level, nutrient deficiencies, and organic matter content, allowing us to customize your fertilization program rather than guessing. Clay-heavy, acidic soils common to Mid-Atlantic states frequently need lime and specific nutrient adjustments. Virginia Green's Estate program includes soil testing as part of the comprehensive service.

• What's the difference between slow-release and quick-release fertilizer?

  Quick-release fertilizer provides an immediate burst of green to jump start growth. Slow-release fertilizer feeds gradually over 6–12 weeks, promoting steady growth, deeper roots, and reduced disease risk. Virginia Green uses professional-grade fertilizer products tailored to the season and turf needs, including quick-release applications in the spring for increased greenup and slow-release formulations in the fall for consistent, long-lasting results.

• How does Virginia Green differ from national lawn care companies?

  Virginia Green is locally owned and operated with 20+ years of lawn fertilizing experience. We maintain a 300-acre research farm where we test products and develop formulations tailored to local soil and grass types. Our in-house agronomists design every program. We also offer a 100% Satisfaction Guarantee with free re-treatments if you're not happy with results.
