Thanks for the warning.

Seem like there is risk of burning the grass whichever way I choose.
Can I simply choose whichever product is available and apply either
one in cool temperature?


I'd go with the muriate, in small doses and only with cool
temps and irrigation.



Are you referring to "muriatic acid" (hydrochloric acid)? I haven't
heard this name before.

Muriate of potash (a dry fertilizer concentrate) is NOT muriatic acid (a
liquid ).

It's been a half century since I had a chemistry class. But, as I
recall, "muriatic acid" is an old, obsolete name for hydrochloric acid
(HCl). And, I believe "muriatic acid" is not pure HCl, but is purposely
adulterated to prevent it from being used in a production line because
it is cheaper than pure HCl.

"Potash" is some sort of potassium (K), probably KNO3. So HCl and KNO3
will probably react to form KCl, potassium chloride ("muriate of
potash"?)you want for your soil, and HNO3 which will evaporate. I'm way
out on a limb here and hope I got it all right and didn't mislead anyone.

Frankly, I wouldn't mess with muriatic acid or muriate of potash. Just
buy standard garden fertilizers which have the N-P-K numbers that suit
your needs.
