A favorite for many, the marigold is a versatile annual flower. There are multiple uses for marigolds. From cut flowers, borders, and companion plants, the options are nearly endless. In fact, there are a few different common types of marigolds that you can select to best fit your gardening needs.
The African marigold (often called giant marigold) has long, sturdy stems and is a great option if you want to grow marigolds for cut flowers. These marigolds are often 3 feet tall. African marigolds have large blooms in a multitude of colors.
French marigolds work great for containers or borders. They also are a great option for companion planting, since they will be shorter than their vegetable companion. French marigolds are usually only up to 12 inches tall.
Finally, the signet (gem) marigold is often used for edible flowers as well as borders and garden beds. They have the smallest blooms and grow 10 to 18 inches tall.
If you are wanting to start flowers from seed, marigolds are a great option to begin with. Start your seeds about 4 to 6 weeks prior to your frost-free date. Lightly cover the seeds with moistened potting media. Seedlings can be set out after the danger of frost.
Marigolds should be pinched to increase branching, which means pinching the top and removing spent blooms. In fact, marigolds reseed easily, and you may be able to enjoy marigolds for years to come by sprinkling the seeds on the soil.
Marigolds are great companion plants for your vegetable garden. Not only do they attract beneficial insects, such as hoverflies, but they also add color to the garden as well and increase biodiversity. Marigolds also can help repel certain pests, such as deer and rabbits, when planted as a border or companion plant.
