The Best Time of Year to Plant Marigolds for Year-round Color

by

Marigolds are popular garden flowers known for their vibrant colors and pest-repellent properties. To enjoy their bright blooms throughout the year, it’s important to plant them at the right time. Understanding the best planting schedule can help you create a colorful, thriving garden all year round.

Optimal Planting Seasons for Marigolds

Marigolds are warm-season annuals that thrive in full sun and well-drained soil. The ideal time to plant marigolds depends on your climate zone, but generally, they are best planted after the last frost in spring. In most regions, this means planting marigolds between late April and early June.

Spring Planting for Early Blooms

Plantting marigolds in spring allows them to grow and bloom during the warm months. If you plant early in spring, ensure the soil has warmed sufficiently, typically above 55°F (13°C). Starting seeds indoors 4-6 weeks before the last frost can give you a head start, or buy young plants from your garden center.

Summer and Fall Care

Once established, marigolds bloom continuously through summer and into fall. Deadheading spent flowers encourages more blooms. In regions with mild winters, marigolds can sometimes survive and bloom into early winter, providing color late into the season.

Extending Color into Winter

In colder climates, marigolds are typically annuals, so they die off after the first frost. However, in warmer zones (8-11), they can be treated as perennials. To extend their color, consider planting them in containers that can be moved indoors or protected during cold months.

Summary

  • Plant marigolds after the last spring frost, usually late April to early June.
  • Start seeds indoors 4-6 weeks before the last frost for earlier blooms.
  • Deadhead regularly to promote continuous flowering.
  • In mild climates, marigolds can bloom year-round if properly cared for.

By timing your planting correctly and providing proper care, you can enjoy vibrant marigold blooms throughout the year, adding cheerful color to your garden regardless of the season.
