[Have a hum of acknowledgement or greeting. Gokudera is in the partially caved-in library. The lighting isn't great, and he's got his glasses on, but he doesn't seem bothered. Uri is off camera, probably playing with debris from whatever explosion caused the cave-in.]

Yours? No. Well... maybe?

[Gokudera rakes a hand through his hair, then puts it up with a small elastic.]

If you wanted to slow down the growth of weeds, you could probably use it directly. But it may be more effective to channel and contain your flames to use them as a weed killer? If it were a vast area, I'd have Kojiro spread them out for you, then plow? Also, maybe the pests would be good food if they're small enough?
