Leaf spot is a common disease found on mums and is caused by fungi such as septoria chrysanthemi, Septoria chrysanthemella and Alternaria. Yellow spots appear on the bottom leaves first and gradually darken until the leaves drop. Other common diseases include:

  • Foliar nematodes: tiny unsegmented roundworms that enter leaves through the stomata
  • Wilt: another fungal disease that can gradually cause stunted growth and death of the mum
  • Bacterial blight: a disease caused by Erwinia chrysanthemi that causes the collapse of the distal portion of the plant.

Planting chrysanthemums in direct sunlight and regularly watering while inspecting for signs of potential disease or infestation will ensure the health of the plant.

  • Q:

    What are some tips on growing mums?

    A:

    Plant chrysanthemums in the spring to ensure the flowers develop a strong root system before winter, and allow potted mums that are purchased in the fall to remain in their containers until spring. Plant mums in a location with at least three hours of direct sun daily. Mums thrive in slightly acidic, well-worked soil that contains organic matter. Use a combination of standard fertilizer and super phosphate, and prune the plants regularly throughout the growing season to encourage ample blooms.
