Actually it's not a TM. You have to get a move tutor in FireRed or LeafGreen to teach it to a Pokemon.
near the berry store there is a man talk to him and he will give you TM bullet seed
This TM doesn't exist in leafgreen.
TM 09 is bullet seed
You have to find/buy the TM Bullet Seed and teach it to the Treecko...
There is no Tm trick in leaf green
