Chrysanthemum Care & Growing Guide

1. Light Requirement

Chrysanthemums like to get a lot of light. Place them in areas where they can receive full sun, around six hours a day, at least. If they don’t receive enough direct light, their stems will grow taller than usual, and they will produce fewer flowers. If they are indoors, make sure they are next to a window that allows the sun’s rays to shine through.

2. Water

This plant requires a lot of water for its flowers to bloom. Always keep new plants thoroughly watered. When they reach their mature stage, they will need about an inch of water a week. If the leaves at the bottom start to turn brown, then it needs to be watered even more. Do not spray them with water overhead; water them right at the soil.

3. Climate and temperature

Chrysanthemums are delicate when it comes to the heat. Their flowers are tender and can easily be scorched by the sun. If they are in pots, do not put them outdoors too early. Wait until the heat of summer has mostly passed. If temperatures are around 85 degrees or higher, the plant won’t flower or bloom to protect itself. Chrysanthemums do best in hardiness zones 5 through 9. This flowering plant also does not do well in the cold or frost.

4. Soil

The right type of soil for chrysanthemums is well-drained soil mixed with perlite. It can’t be too dense because then, the roots can’t grow farther, and the water will stay stagnant around the plant, causing disease and rot. If you need to fertilize the soil, do it once or twice a month and stop when cold weather sets in. Try to keep the soil’s pH around 6.5.

5. How to repot Chrysanthemums?

Generally, springtime is the best time to repot a chrysanthemum. Before you repot a chrysanthemum, water it the day before you mean to change it out. The soil sticks better to the plant if it is damp. Retrieve a larger pot and fill it with 3 inches of good potting soil, then take the plant and turn upside down. Wiggle the plants out of the pot. After, place the chrysanthemum with its potting soil and roots and all into the new container and slowly fill the chrysanthemum plants up with new soil. Then water it slightly and place it in indirect sunlight.

6. Speed of Growth

Since there are so many types of chrysanthemums, it’s hard to establish a basic growth speed. Some plants take several years to reach three feet, but others can reach it in only one. But what does affect the rate of growth is proper lighting and moist soil.

7. Height and width of the plant

One single chrysanthemum plant can grow to be three feet tall. Its width can reach up to 3 feet as well.

8. Trimming

Chrysanthemums need to trimmed or pinched in the early summer. First, you must remove all foliage that does not end in a flower. Also, remove all of the dead or decaying foliage. If the foliage needs to be pinched back, it must be done before July 13th. This is because it will not delay the flowers bloom later in the year. 

How do I propagate Chrysanthemums?

Yes, the chrysanthemum plant can be propagated. First, remove a full strong stem that has no flowers. Then remove the bottom leaves if there are any. Then dip the cut part into the root hormone and repot it into a small container with soil. The cuttings take about four to six weeks to develop strong roots.
