How to Grow Rainbow Chrysanthemum From Seed

Updated February 21, 2017

Chrysanthemums, also known as mums or garden mums, are a staple in many gardens across the U.S.. Mums grow well in a sunny, well-drained location in your garden. Rainbow chrysanthemums are a special mix of annual chrysanthemums that come in a variety of colours including red, pink, yellow, white and orange. Rainbow chrysanthemums can be grown from seed easily and placed in your garden when the weather warms up.

  1. Fill the seed trays full of seed starter. Water the seed starter until it is moist but not soaking.

  2. Press the rainbow chrysanthemum seeds in the seed starter about two to four weeks before the last frost in your area. Keep the starter moist at all times.

  3. Place the seed trays in a location with a temperature of 21.1 degrees Celsius. The seeds will germinate in six to 10 days.

  4. Plant the rainbow chrysanthemum seedlings outdoors once the air temperature is at least 20 degrees Celsius. Dig a hole for the transplants as deep as the root ball and twice as wide. Space the holes 18 to 24 inches apart. Place the chrysanthemums into the holes and fill the holes with soil.

  5. Tip

    Plant the rainbow chrysanthemum seeds outdoors after the spring frost has past.
