Chrysanthemums are common gift plants and can be found as such year around. This is because they have been tricked into blooming by either hormones or manipulation of light exposure. Chrysanthemum houseplants require lower light to force blooms. They can be quite difficult to get to re-bloom in an interior setting, but in warmer climes should be planted outside where they can get the appropriate lighting and resume their normal bloom schedule. Potted mums are not the same as the hardy varieties that go into garden beds. They are more sensitive to cold and light changes, but you can find them any time of the year and bloom for several weeks in the home interior. Growing chrysanthemums indoors is easy and requires little special care beyond watering, good soil and drainage. Once the blooms are spent, you can keep the plant around for its deeply etched foliage.
Mums require even moisture for the best growth. Consistent watering throughout the spring, summer and fall is essential.
Because mums require the proper sunlight to set blooms, placing your plant in a south-facing window and away from artificial light produces the best results.
All plants require nutrients. Fertilizing your mums gives them an added boost of essential nutrients for the best growth.
