  • Natural and chemical treatments are available for pest control.

Identifying Common Pests Eating Mums

Aphids

Aphids are tiny, soft-bodied insects that can be green, black, brown, or pink. They cluster on the undersides of leaves and stems, sucking the sap and causing leaves to yellow and curl. Aphids also excrete a sticky substance called honeydew, which can attract ants and lead to the growth of sooty mold.

Spider Mites

Spider mites are minuscule pests that are often difficult to see with the naked eye. They thrive in hot, dry conditions and can cause significant damage to mums. Look for fine webbing on the undersides of leaves, stippling or yellowing of the leaves, and a general decline in plant vigor.

Caterpillars

Caterpillars, such as the chrysanthemum webworm and other moth larvae, can chew large holes in the leaves and flowers of mums. These pests are often easy to spot due to their size and the noticeable damage they cause.

Thrips

Thrips are tiny, slender insects that feed by puncturing plant cells and sucking out their contents. They can cause stippling, discoloration, and scarring on the leaves and flowers. Thrips are often found inside the blooms, causing them to become distorted and discolored.

Slugs and Snails

Slugs and snails are common garden pests that feed on the foliage of mums, leaving irregular holes and a slimy trail. They are most active at night and during damp conditions.

Signs of Pest Damage

Chewed Leaves

Large, irregular holes in the leaves are a clear sign of caterpillars or beetles. This type of damage is usually easy to spot and often occurs quickly.

Discoloration and Stippling

Yellowing or stippling on the leaves can indicate an infestation of spider mites or thrips. These pests suck the juices from the leaves, causing them to lose their color and vitality.

Webbing

Fine webbing on the undersides of leaves is a telltale sign of spider mites. The webbing can protect these pests and their eggs from predators and harsh environmental conditions.

Honeydew and Sooty Mold

A sticky substance on the leaves, known as honeydew, can attract ants and lead to the growth of sooty mold. This is often a sign of an aphid infestation.

Preventing and Managing Pest Infestations

Regular Inspection

Regularly inspect your mums for signs of pests. Check the undersides of leaves, stems, and flowers. Early detection is key to managing infestations before they become severe.

Proper Watering and Fertilization

Healthy plants are more resistant to pests. Ensure your mums receive adequate water and nutrients. Avoid overhead watering, which can create a favorable environment for pests and diseases.

Natural Predators

Encourage natural predators like ladybugs, lacewings, and predatory mites in your garden. These beneficial insects can help control pest populations.

Neem Oil and Insecticidal Soap

Neem oil and insecticidal soap are effective, organic treatments for many common pests. Apply these treatments according to the label instructions, ensuring thorough coverage of the affected plants.

Chemical Treatments

For severe infestations, chemical insecticides may be necessary. Choose a product labeled for use on mums and follow the instructions carefully. Use chemical treatments as a last resort to minimize harm to beneficial insects and the environment.
