So, first start the game (it has to be a new game). When it asks you if you want help, click yes. Then follow the instructions till you get to the one that says, "One of your plants has produced seeds! The seed appears in the seed area..." and so on. Then collect the seeds and then hit the "replay tutorial instruction" (at the top of the screen) and you get extra seeds even though the plant was depleted.
