Growing Tips
- 1Marigolds thrive in full sunlight, so plant them in a spot that gets at least 6 hours of direct sun each day.
- 2Water them regularly, but allow the soil to dry out between waterings to prevent root rot.
- 3Use well-draining soil and space the plants about 8 to 10 inches apart to ensure good air circulation, which helps prevent disease.
- 4For pest control, marigolds are generally pest-resistant, but you can use natural remedies like neem oil if needed.

How to Harvest
- 1Harvest marigold flowers when they are fully open and vibrant in color, typically in the morning after the dew has dried.
- 2Use sharp scissors or pruning shears to cut the stem just above a set of leaves to encourage more blooms.
- 3Avoid pulling the flowers to prevent damaging the plant.
Step 5
Saving Seeds
How to Save Seeds
Saving seeds from your Marigold plant is easy and rewarding, even for new growers! Once the flowers have faded and dried on the plant, simply pinch off the brown, dried flower heads and gently pull them apart to reveal the slender, black-and-white seeds inside. Let the seeds dry completely in a cool, airy spot for a few days, then store them in a labeled envelope or small paper bag in a cool, dry place until you’re ready to plant again. You’ll be amazed at how simple it is to grow next year’s beautiful blooms from your very own saved seeds!
