Buy new plants, grow them to full size, then sell them. Repeat this to earn more money. You can also use this trick when you have to get Marigolds in Crazy Dave's shop and they are out of stock . Also, if you don't want to change the date, you can give chocolate to your plants to make them give money faster. But be sure that your plants are fully matured.
