Q.Where to get soil analysis

Zone 10014 | Anonymous added on January 21, 2020 | Answered

I have a a curbside city planted tree to which I wanted to add some annual flowers and other plants.
I’d like to amend the soil and need to know what minerals to get.
Where might I send a dirt sample for analysis?
Thank you
