Well, I've beaten the stage now and I'd say I can't seem to use Garlic very effectively in this stage, so I stuck with my previous strategy through most of the levels. As it turns out though, Primal Wall-nut is actually more useful (IMO) than Infi or Chard in this stage. I've used it to defend against Raptors with ease so I can save Perfumes for Pterodactyls and sometimes Stegos.

The ability to set up a defensive plant, even a weak one, at almost any time is surprisingly useful and seems to be the one thing preventing some of the later levels from being BWB-difficulty.
