Question
I live in west tn and want to know if it is the right time to spray my lawn for weeds such as henbit and other weeds and also onions?  what do i need to use to spray it with. it is a small lawn

Answer
Once the grass is actively growing, and you see the weeds emerging, it's time to apply a selective weed control product. You can use something like "Weed-B-Gone" or any of a large number of products that are labeled safe for lawn use. Just make sure to avoid a "non-selective" product.

That link is a pretty good one to better demonstrate how you can do it properly.

Good luck!
