Need help with fertilizer for lawn
Posted on 3/5/25 at 12:22 pm

Soil Sample results came in:
recommends
14.40lbs/1000sq ft of Ammonium Sulfate
1.5lbs of Triple Super Phosphate
0 Potassium
St Aug is the grass type (fresh sod laid three weeks ago)
Soil is low on Sulphur
Medium on Phosphorus
Everything else is good
Any recommendations for a fertilizer or should I just use Scotts Turf Builder?

Something with a "0" for the last number = no potassium. (3 numbers stand for N-P-K, Nitrogen-Phosphorous-Potassium)
That's all I got....

Don't do anything to your lawn until it is rooted and you have had to mow twice. I don't do soil samples because most don't tell you very much and getting some sort of custom blend specifically for your lawn is impossible. Site One sells a 16-0-4 which is a good mix for St Aug.

Why not use what they recommend?
Need nitrogen, lower pH, and a little phosphate.

sod comes heavily fertilized from the sod farm to begin with. Let the sod take root and start growing on it's own before dousing it in fert.
Also definitely do not do this

Agreed. I think you would absolutely torch it with 18lbs. I assume you tested the soil underneath. Not the soil attached to the new sod.
