Keep your Columbia lawn healthy through Maryland's brutal summers with professional fertilization from Greenlawn Inc. Serving Howard County since 1986.
Cool-season grasses struggle with Maryland's heat and humidity. Summer fertilization requires careful balance—enough nutrition to stay healthy without forcing growth that increases stress. Professional application prevents burn and maintains color safely.
Professional fertilization protects against heat stress

Slow-release nitrogen (0.5-0.75 lbs/1000 sq ft) provides gentle feeding without forcing growth or increasing burn risk.
Potassium strengthens cells, improves heat tolerance, and helps grass regulate water—often equal to or higher than nitrogen.
Iron provides green color without nitrogen's growth-forcing effects—perfect for summer stress conditions.
Early Summer (Mid-June): First application bridges spring to fall, providing steady nutrition before peak heat arrives.
Late Summer (Late August): Second application prepares grass for fall recovery as temperatures moderate.
Mid-Summer (July): Generally avoided due to peak heat and higher burn risk. Only applied with adequate irrigation.
No. Fertilizing when temperatures exceed 90°F can cause severe burn. Wait for cooler periods (below 85°F) with adequate soil moisture. We monitor weather carefully and postpone applications during dangerous heat.
Not essential like spring/fall, but provides major benefits—better color, improved stress tolerance, and healthier turf. If budget is tight, prioritize spring and fall first, then add summer.
Yes. Apply ¼-½ inch within 24 hours to move granules into soil and reduce burn risk. Continue regular watering (1-1.5 inches weekly) to help grass use nutrients effectively.
No. Spring fertilizers have too much quick-release nitrogen for safe summer use. Summer needs specialized low-nitrogen, high-potassium blends. Save spring fertilizer for next year.
