Bonanza Mix Marigolds item #06789



Marigolds are easy-to-grow, popular flowering annuals commonly used for massed plantings, borders, cut flowers, and in containers. There are several different types of marigolds. All are long-blooming and have fragrant foliage.

  • American types (Tagetes erecta) are also called African marigolds. They are upright in habit and have large, double flowers in solid colors.
  • French types (Tagetes patula) are more compact in habit than American types and they can have single, semi-double, or double flowers. Flowers can be single colored or multi-colored.
  • Signet types (Tagetes tenuifolia) have small, single flowers, lacy foliage, and a compact, mounded habit. Their foliage has a citrus scent.

All types of marigolds are attractive to butterflies and other pollinators and all have edible flowers. Marigolds are commonly planted as companion plants in vegetable gardens to attract beneficial insects and some believe that they help to repel garden pess.

How To Plant

Start seeds indoors 3 to 4 weeks before the last spring frost. Plant seed a quarter inch to half an inch deep and maintain at 70 to 75 degrees F. Expect germination in 5 to 14 days.

Marigolds can also be direct sown in the garden after the last spring frost.


For full sun locations in well-drained soil. Deadheading helps to ensure continued strong blooming.

Fertilizer Recommendations

Marigolds are moderate feeders that benefit from occasional fertilization. Use ALGOplus Flowering Plant 4-6-7 liquid fertilizer or Neptune Fish & Seaweed Fertilizer 2-3-1.

Common Problems

Marigolds are generally not bothered by insects or diseases. Slugs and snails occasionally feed on plants. Spider mites can be a problem during prolonged hot, dry weather. American types may lodge (fall over) after heavy rains, as their large flowers hold water and can become heavy.

Alternative Products

Other easy-to-grow warm season annuals include cosmos and zinnia.

Complimentary Products

Use Sluggo Plus if slugs and snails attack plants. 70% neem oil can be used to control spider mites.
