Formula Used
The amount of Ortho Dial N Spray needed is calculated using the following formula:
Total Gallons = (Lawn Size ÷ 1,000) × Application Rate
Where:
- Lawn Size = Area of your lawn in square feet
- Application Rate = Recommended amount per 1,000 square feet (typically 1-2 quarts)
The calculator uses this formula to provide an accurate recommendation for your specific lawn size.
Worked Example
Let's say you have a lawn that's 5,000 square feet and you want to apply Ortho Dial N Spray at a rate of 1.5 quarts per 1,000 square feet.
- Divide the lawn size by 1,000: 5,000 ÷ 1,000 = 5
- Multiply by the application rate: 5 × 1.5 = 7.5 quarts
- Convert quarts to gallons (since the product is sold in gallons): 7.5 quarts ÷ 4 = 1.875 gallons
You would need approximately 1.88 gallons of Ortho Dial N Spray for your 5,000 square foot lawn.
Note: Always follow product instructions and local regulations when applying lawn care products.
