Got a plant question or want to brag about your flourishing flower and veggie gardens?

Head to the State Fair Star Tribune booth to hang out with the Greengirls bloggers. Play a game that tests your knowledge about what you can or can't compost and what's a garden friend or foe  -- and win prizes, too.

Greengirls will be at the Strib booth -  right at the bottom of the Grandstand ramp - from 1 to 3 p.m. Aug. 31 and 5 to 7 p.m. Sept. 2.

We welcome all green thumbs – from novices to know-it-alls.
