When you're at the garden, click on the plot of land that you want to plant at. And when you're at the Market, look in the top right corner to see if you can get a bargain on any plants! Different seeds take different times to grow. Marshmallows are the slowest, and beans are the fastest. Click on a plant once it's ready to harvest it, and then go to the Market and click on the corresponding square to sell.
