How to Grow Harlequin Marigolds

An heirloom cultivar of French marigold, the Harlequin marigold (Tagetes patula) has alternating burgundy and gold petals for a statement flower. Marigolds, including this one, grow as annual flowers and bloom from spring until fall, standing up to both the high heat of summer and periodic droughts. Plant Harlequin marigolds from start or seed in late spring when fall danger passes for your area, and find them at your local garden center or order seeds from a supplier.

Instructions

- 1
  Choose a full sun location for this bloom. These marigold spread up to 4 feet, so allocate plenty of garden real estate.
- 2
  Dig one hole for each plant, spacing holes 6 to 9 inches apart. If planting from seed, dig a trench 1/4 to 1/2 inch deep.
- 3
  Place your marigold plants in the holes so the roots spread out against the soil. Holding the plant straight, fill in the hole with soil to complete planting. For seeds, plant one seed every inch and fill in the hole with soil. When seeds germinate, thin to allow 6 to 9 inches of space between each.
- 4
  Water the soil after planting your Harlequin marigold plants or seeds to saturate the earth.
- 5
  Continue to water the marigolds when the soil becomes dry to the touch, adding liquid to saturate the soil.

  Watch out for insect problems. Marigolds may be bothered by spider mites or grasshoppers, both of whom munch plant matter, leaving a trail of holes. Treat with an insecticidal soap if a problem arises.

  Cut stems back to the ground in autumn as part of a fall cleanup.
