In Big Bad Butte, if the minecarts allow me and I'm not overwhelmed, I try to stall Gargantuars as much as possible. When Gargantuars come near a minecart, plant any plant on it (the best would be spikerock, or some attacking plant). When it's about to smash it quickly move the minecart, then place it back again. The Gargantuar will keep standing there, trying to smash the plant, until your plants kill it. If you have Wintermelons or Snow Peas, that's even better since you can take out more damage that way and easily deal with multiple gargantuars.

This also works for multiple Gargantuars (I tried, and it worked), but you may get overwhelmed after a while (obviously). I use this for emergencies and early Gargantuars.
