It's a question asked perhaps more than "what's for dinner?" - - - "What's my spreader setting?"
While there are spreader setting charts out there that list common settings across a wide variety of different spreaders (Lesco, Scotts, Earthway, etc etc), you should always CALIBRATE your spreader to accurately calculate the desired rate for the desired product.
"How do I know how much fertilizer to use?" - Here is an example to help you figure that out.
You have a 10,000 sq ft lawn & you're going to fertilize using our 18-0-3.
1) Choose a desired rate of Nitrogren to be applied per 1,000 sq ft
(for this example, I will use .5 lb N per 1,000 sq ft)
2) Divide your desired rate by the percentage of Nitrogen in the bag - this will tell you how many lbs of fertilizer you will need to apply per 1,000 sq ft to achieve your desired rate.
(.5 lb N / .18 N) = 2.78 lbs per 1,000 sq ft.
3) Your lawn is 10,000 sq ft so if you multiply that number (2.78) by 10 - this will tell you how many lbs of fertilizer you will need for the job.
(2.78 x 10) = 27.8 lbs of 18-0-3
Now, you need to calibrate your spreader to apply 2.78 lbs of 18-0-3 per 1,000 sq ft

Materials you will need:
- bucket or pail
- scale
- your spreader (don't laugh - you really need it)
- paint can
- marking flags (or anything to help you mark a point of reference)
- measuring tape or wheel
