Do tomato plants need to be planted every year or are they perennials?

Also, what about marigolds, mandevilla, and four o'clocks?

Do tomato plants need to be planted every year or are they perennials?
You'll need to plant them every year in spring indoors then transfer to outside when about 6-8 inches high.


Old plants will produce fuit if kept alive but not nearly as bountiful as fresh new plants.


Marigolds produce seeds and will come up again year to year without the need to replant. You may want to spread them out once they do start to come up to avoid over crowding and get full coverage.

Reply:Yes sweetie, they are annuals, but you can sve the seeds from your tomatoes dry them out and plant them, that way you do not have to buy plants, saves a lot of money that way.
