Chrysanthemums Features: An Overview

  • These plants belong to the Chrysanthemum genus that contains about 40 species of flowering plants. They grow mostly in subtropical and temperate areas.
  • Chrysanthemums are perennial herbs or subshrubs. Depending on the species, they can reach from 15 to 40 inches (40-100 cm) in height and usually have a similar spread rate.
  • Their foliage consists of simple, aromatic, and green leaves that appear alternately arranged on long, upright stems. The leaves contain numerous tiny toothed leaflets but can show up with smooth margins occasionally.
  • Chrysanthemums begin their blooming period in early autumn. During this season, they produce many inflorescences that contain arrays of several flower heads or, sometimes, a solitary blossom.
  • While their flowers typically have both disk and ray flowers, some cultivars can lack either of them. They vary in shape and size and exhibit different shades of white, yellow, orange, red, pink, purple, green, or even hypnotic combinations.
  • Due to their generous colour palette, Chrysanthemums can make for good-looking companions to other species of plants. Some of these are Alyssum, Blue Fescue, Coneflower, Asters, Oriental Fountain Grass, and Reblooming Daylily.

Growing Chrysanthemums

When it comes to lighting, Chrysanthemums generally thrive in full sunlight. Under this kind of light exposure, your plants will reward you with the most profuse blooming. Still, they can also tolerate some shade once in a while. In fact, if you live in a region with a warm climate, your flowers will often appreciate some shade during the dry and hot summer afternoons.

In terms of temperatures, Mums do well in moderate climate conditions. While extreme heat can result in overall struggling plants, your fellows will also suffer in areas with hard winter freezing. As a general rule, these flowers perform best in USDA zones 3 to 9 without any extra effort on your part. In cooler regions, you can help your plants go easier through winter by covering their roots with a deep layer of mulch.

Although Chrysanthemums are pretty tough ornamentals, they can suffer when pests like aphids, spider mites, and thrips visit them too often. These intruders usually show their presence through leaf damage, unhealthy stems, or a cotton-like web. In case of infestation, you must handpick the pests, then apply neem oil or, for severe situations, suitable insecticides/pesticides.

Other common problems that can occur while growing and caring for Mums are diseases. Some of these are leaf spots, powdery mildew, rust, root rot, or botrytis. If you notice that your plants behave somehow oddly, they may go through a disease fight. While powdery mildew and leaf spots are rarely life-threatening, you have to remove and get rid of the plants that are affected by these diseases before the problem spreads to other plants.

Planting Chrysanthemums

If you want to witness a dramatic and exquisite show during the autumn months, the ideal time to plant your Chrysanthemums is in spring. These plants usually bloom at the end of the summer or during the fall. Planting them in spring will help your buddies to develop a strong enough root system to support their flowers. Likewise, a good root system will enable your plants to resist the harsh conditions of autumn and winter much better.

In general, Mums can tolerate a wide range of soil types without any future problems. However, they grow at their best in rich, somewhat acidic substrates that also come with excellent drainage. Poor soil drainage may cause your beloved plants to rot with time. If you would like to keep your flowers indoors, plant them in pots that have drainage holes at the bottom.

During their dormant period, your Chrysanthemums will need some potassium and nitrogen to remain in their best shape. So it’s best to feed them before their flowers buds form, typically in March, April, or May. The best product to fertilize these plants with is a time-released 12-6-6 fertilizer because it will provide them with enough nutrients for about three months.

For container-grown plants, regular repotting is mandatory. Chrysanthemums grow at a pretty fast pace, so they will outgrow their pots and also overcrowd their roots. Transplant your plants in new containers that are a bit bigger than the current ones. You can also trim the roots if you want to control their future spread, but be gentle and try not to damage them.

Watering Chrysanthemums

Chrysanthemums need lots of water to grow healthy and happy. During their first growing season, your flowers will do just fine with just one inch (2.5 cm) of water weekly. Once their flower buds reach maturity and they begin to open, you can increase the frequency of watering to 2-3 times per week.

You can avoid over-watering your Mums by checking their soil regularly. When the top inch (2.5 cm) of soil feels dry to the touch, you can give your flowers a nice drink.


Propagating Chrysanthemums

Chrysanthemums are so charming and easy-going that you surely want to have as many as possible. Especially since, in all their splendour, they can make for superb gifts for your beloved family members or friends. If you wish to make more of these flowers, you can easily propagate them through division or cuttings with no extra expenses.

It is possible to divide your Mums only after they have grown in your garden for at least two years and have at least 6 inches (15 cm) in height. Once established, you can divide these plants once every three years in spring. This process will also rejuvenate your companions and keep them alive for a long time. All you must do is dig your plants out of the soil, divide their roots into tiny sections, then replant them in their permanent locations.

Propagation using cuttings is an effective method to get a replica of your Chrysanthemums. Look for healthy stems and cut about 4 inches (10 cm) off them with a sharp, sterilized knife. For optimal results, you can also dip the cut ends in a rooting hormone. After this step, plant them in pots and wait about four weeks or so to develop a healthy root system.

In Conclusion

Chrysanthemums have always found ways to win every gardener’s heart, so you will surely be their next victim! With their showy, colourful flowers, they can fill any dull spot from your garden or home and produce beautiful blooms with little to no effort on your part.
