How to Manage Pests

Common abiotic disorders of Chrysanthemum

Damage symptoms on Chrysanthemum can be caused by nonliving or abiotic factors including excess or deficient water, nitrogen or other mineral deficiencies, or temperatures that are too hot or too cold. For example:

• Inadequate water causes plants to wilt and drop leaves. Excess water causes root rot and death of plants.
• Nitrogen deficiency causes leaves to yellow uniformly, beginning with the older foliage; other mineral deficiencies cause mottling or discoloration of leaves.
• Damage caused by herbicides, salts, or other mineral toxicities, may cause plants to become distorted or stunted, or leaves to brown or yellow at the margins.

Solutions

Prevent abiotic disorders by properly following irrigation and fertilizer recommendations and making sure that herbicides don't drift over into your planting beds.
