If you know the different types of marigolds, which we will discuss in the next section, you will be able to identify how many seeds are recommended per square, per hole, or per pot. You must also keep in mind some important details, like how much space each marigold needs. 

You will have to consider your pots before planting your marigolds. They do play an important role if you plan to grow potted marigolds.
