Single Packet of 500 Seeds
Grow a garden filled with Mary Helen African Marigolds, from freshly harvested Tagetes erecta seeds. Mary Helen is an African variety of Marigold that will produce gorgeous, brightly colored blooms through the summer months. Each flower ranges in size from 1.5 to 2 inches in diameter, and displays tightly packed rows of golden yellow petals. Mary Helen will grow to a mature height of roughly 24 to 36 inches tall, and can spread roughly 12 inches wide.
You might be surprised to know that Marigold flowers are not only attractive, but they will deter pesky insects as well. Bugs such as mosquitoes, fleas and ticks will stay away from these beauties. However, they will also attract an array of beneficial insects to the garden as well, such as butterflies, bumblebees, honeybees, hummingbirds and even lady bugs. Marigolds look great in flower beds, raised beds, along borders and even in large pots and containers as well.
Marigold plants are grown as annual flowering plants. Annuals will grow quickly from freshly harvested seeds, bloom profusely through the summer months, and will later die with the first signs of frost. You can easily collect seeds from spent blooms at the end of the season, for resowing the following year. Seeds can also drop to the bare ground beneath, establishing fresh plants in the Spring.
To extend your bloom time, try to prune and deadhead your Marigold flowers, so that fresh flowers can take their place. Look for old and withered flowers and simply pop the heads off, or snip with a pair of scissors.

Sowing The Seed
Marigolds are among the easiest plants to establish from seed. They can be sown directly outdoors, or in starter pots, 6 to 8 weeks prior to the last forst. If started indoors, sow at a depth of 1/16” under topsoil, in peat pots. Transplant or direct sow outdoors when the weather is warm and all danger of frost has passed. Keep in mind that Marigold seeds will require a bit of direct light to properly germinate. Do not cover more than the reccommended sowing depth mentioned above.
Marigold flowers will thrive in an area of full sunlight for the majority of the day. Temperatures should be at least 65F to 70F for optimal growth to occur. The soil should never be too fertile, as this will cause your foliage to grow, with little blooms. The sowing medium should be well drained however. To improve drainage, we always recommend that you add in a light compost to your sowing area. Water the seeds daily until germination has occurred.
Germination & Growth
Marigold seeds will typically germinate within 7 to 14 days after sowing. The plants will reach a mature height of roughly 24 to 36 inches tall and can spread roughly 6 inches wide. You can space your marigolds about 12 inches apart from one another. The production of new, fresh flowers can be achieved by dead heading or pruning.
