Chrysanthemums are flowers that are most commonly referred to as mums and they are a popular gift for Mother's Day. Chrysanthemums can be grown outdoors or indoors depending on the location. Once the seeds have germinated it's best to have the plants kept at a temperature that is between 70 and 75 degrees. For several chrysanthemums to propagate in an area, such as a greenhouse, you must sow the seeds in flats with a sterile rooting medium. It's also important that the stems are cared for and never damaged, which could automatically kill the plants.
Start your planting of the flowers at least six weeks after the last frost of the winter season. Typically, you should be planting at the beginning or middle of April to ensure the best growth of your flowers in time for spring.
Wash the chrysanthemum seeds and place them into a container. Don't cover the container as the seeds will need light to germinate. Place the container under a kitchen light or window sill overnight. The seeds will germinate within 7 to 28 days.
Plant the seeds at least 1 inch deep and wide in your garden outside. Space each seedling 45 to 60 cm apart in the garden bed (see References). Cover the holes and water immediately using a 1/2 cup of water.
Continue watering the plants one to two times a day with a 1/2 cup of water or whenever the soil is dry. Spread fertilizer around the seedling after one week of being planted outside. Use 15-30-15 fertilizer for the best results.
Make sure that your chrysanthemums continue to receive plenty of light and water. Continue water one or twice a day as needed and fertilize one more time during the middle of summer.
