I have an interview with Lime Light Marketing Chicago and they don't have a website, which is not a good sign for a marketing company. Is this a pyramid scheme type job?
Lime is not a food, it is a soil amendment.
I would not put lime under a fig tree unless I get my soil tested for PH. Lime might raise the PH too high. If your soil is acid, then you could add lime to your soil, otherwise leave it alone.
