Chrysanthemums are best when they are planted in the early spring, though they are safe to plant during any season. Mums usually bloom in the fall.
When choosing the right time to plant mums, make sure the frost is over and the weather forecast doesn't call for any freezing days in the near future. This is why spring and summer are ideal for planting mums. The plants need to have enough time to establish their root systems before the hot season arrives, so avoid late summer for planting.
Mums need a minimum of six hours a day of direct sunlight. They do good in soil with excellent draining potential. They are best when grown alone; water mums regularly for optimal growth.
