Fertilizing during peak
summer heat requires caution and precision. Applying too much nitrogen too soon
can backfire, fueling excess top growth, raising water demands, and encouraging
disease.
Follow
these expert-backed tips to manage fertilization wisely:
- Go Easy on Nitrogen:
During mid-summer, extension programs across the Southeast recommend no more than ¼ pound of actual nitrogen per 1,000 ft², and only when grass shows visible fading. Excess nitrogen forces top growth, increasing water demand and vulnerability to disease.
- Avoid Forcing Growth:
Tall fescue can withstand temporary dormancy during hot weather. Pushing it to stay green through high-nitrogen feeding risks triggering brown patch disease and significantly increases irrigation needs.
- Watch Night Temperatures:
Resume a more balanced feeding routine only once nighttime temperatures fall below 70°F, typically in early September. Cooler conditions support safer nutrient uptake and better root development.
- Targeted Fertility = Long-Term
Health:
Feeding lightly during summer helps the lawn conserve energy and moisture, while still preserving its ability to bounce back once fall arrives.
- Trust the Experts:
A reputable lawn service in Clifton VA can assess lawn color, soil condition, and seasonal timing to apply the right amount of fertilizer at the right moment, without overdoing it.
