Ortho Dial N Spray with powder mix
How do I use powdered fertilizer, pesticide, etc with my Ortho Dial N Spray? Simple, dilute the powder. I had the same problem. I had a box full of Miracle Gro All Purpose fertilizer, the ECONOMY box. By the time I went through the first little baggy, I was tired of premixing in 5 gallon buckets. I already owned the Ortho Dial N Spray, which I successfully used to murder my lawn before planting new grass. That thing comes well recommended online and in person. So how much to mix into this contraption?
For All Purpose Miracle Gro which uses a 1 tablespoon to 1 gallon ratio, simply:
1) Fill the Dial N Spray halfway with powder (16oz line)
2) Fill the rest with water (32 oz)
3) Stir or shake vigorously and make sure all of the powder has been diluted into the water. We don’t want to clog the apparattus ; ).
4) Set the dial to 1oz.
Why this works:
Forget about the 16oz we added, this amount of water is negligible, when considering the gallons we’re pouring out in total.
When filled up to 32 oz, spraying at 1oz per gallon, the sprayer will spray a total of 32 gallons of water. 10z is 2 tablespoons. This means with a full bottle, dialed at 1 oz, we will mix a total of:
32 gallons of water total, with 64 tablespoons of solution.
This is a 2TB/gal ratio (too much)
So by cutting the powder down to 16 oz, we’re left with:
32 gallons of water total (can’t change that), 32 tablespoons of solution.
Thus, 1 Tbsp Powder/ 1 Gal Water
Fill the reservoir with half-powder, half water. Set the dial to twice the amount of powder recommended per gallon, and you’re done. Assuming, of course, that the recommended amount is on the dial.
Remember 1 oz = 2 Tbsp = 6 Tsp.
