Chrysanthemums have a rich history and there is much more than can be said about this garden beauty but let’s take a closer look at the growth and care of chrysanthemums.

When planting chrysanthemums give a spacing of 18-24 inches. This spacing will provide the proper airflow or circulation safeguarding against fungal issues.

Water requirements for chrysanthemum

The soil should be kept moist but not waterlogged, check the soil on a weekly basis to ensure that the soil is not completely dry. Applying mulch around your chrysanthemum will help to conserve water, hold weeds down and as the mulch decomposes will add nutrients to the soil.

Garden pests of chrysanthemums are as followed.

  • Earwigs
  • Aphids
  • Slugs
  • Snails
  • Thrips
  • Leaf Miners
  • Mites


Although these garden insects help to eliminate insect pests that will destroy garden plants they too cause damage by eating parts of the plant’s leaves along with leaving behind their excrement which is black. To control earwigs the use of diatomaceous earth will offer help. Diatomaceous earth is only effective once the ground is dry, placing a ring of diatomaceous earth around your plants will give results.


Aphids are pear-shaped and can either be black, red, yellow, green, or brown. Aphids are among the sucking insect group and will cause flowers to drop. These garden insect pests also produce a sticky substance known as honeydew. This honeydew is their excrement that causes sooty mold to form. Applying soapy water or insecticidal soap will bring aphid infestation under control.

Slugs and Snails

Slugs and Snails are among the chewing garden insect pests and dose damage by feeding on the leaves of garden plants. To bring control handpicking them and throwing them into a bucket of soapy water or applying snail bait will offer help.


Thrips are tiny insects that can be either red, black, yellow, or dark brown. Thrips can cause serious damage because they have been known to carry viruses along with extracting the plant’s fluids causing leaf drops and failure with flower bloom. To control thrips prune or remove infected plant parts including the flowers. The use of neem oil or insecticidal soap will also eliminate them.

Leaf Miners

Leaf Miners will do damage the same as earwigs, control these garden insect pests the same as you would earwig. The use of insecticidal soap along with the removal of infected leaves will give good results.


Spider mites are very tiny, they are hard to spot but the damage of these small insects can be very server. Spider mites do damage the same as aphids with yellowing of the leaves. To test if your plant has spider mites place a white sheet of paper under the leaves and tap if spider mites are the culprit you will see tiny mites moving around on that white sheet of paper you may also feel them crawling on your hands. The presence of webbing is another sign of spider mites the use of a miticide label for spider mites will bring the infestation under control.
