Most Common Mum Plant Information Pests:
Identification and Treatment Guide

Mums, also known as chrysanthemums, are popular flowering plants that add vibrant colors to gardens and landscapes. However, like any other plant, mums are susceptible to pests that can cause damage and hinder their growth. In this article, we will discuss some of the most common pests that affect mum plants, how to identify them, and the best treatment methods to keep your mums healthy and thriving.

Aphids

Aphids are tiny insects that can be found on the leaves and stems of mum plants. They are usually green or black in color and feed on the sap of the plant. The presence of aphids can cause distorted leaves, stunted growth, and a general decline in the overall health of the mum plant.

To identify aphids, look for clusters of small insects on the undersides of leaves or curled leaves. You may also notice sticky residue or black mold on the leaves, known as honeydew, which is a byproduct of aphid feeding.

To treat an aphid infestation, start by removing heavily infested leaves or stems. You can also hose down the plants with a strong stream of water to dislodge the aphids. In cases of severe infestations, consider using insecticidal soap or neem oil spray. These organic treatments help suffocate and kill the aphids without harming beneficial insects.

Spider Mites

Spider mites are another common pest that infests mum plants. These microscopic pests are barely visible to the naked eye but can cause significant damage if left untreated. Spider mites feed on the plant’s sap, leading to yellowing leaves, webbing on the undersides of leaves, and overall wilting.

To identify spider mites, examine the underside of mum leaves for tiny specks moving around. You may also see fine webbing between leaves or on the stems. Another way to detect spider mites is by tapping a leaf over a white piece of paper and looking for tiny moving dots.

To treat a spider mite infestation, start by pruning heavily infested leaves or stems. Increase humidity around the plant by misting it regularly or placing a tray of water nearby. You can also use insecticidal soap or neem oil spray to control spider mites. Repeat the treatment every few days until the infestation is under control.

Slugs and Snails

Slugs and snails are common garden pests that also target mum plants. These mollusks feed on the leaves and flowers, leaving irregular holes and chewed edges. Slugs and snails are often active during damp and cool conditions, so they are more prevalent in spring and fall.

To identify slug and snail damage, look for irregular holes on mum leaves, slime trails, or the presence of the pests themselves. You may also notice damage to flowers, which can prevent them from fully blooming.

To control slugs and snails, start by removing any hiding spots around the plants, such as rocks or debris. Handpicking them off the plants is an effective method if you have a small infestation. You can also create barriers around the plants using copper tape or diatomaceous earth to deter these pests. Organic baits like beer traps or iron phosphate pellets can also be used to control slugs and snails.

Thrips

Thrips are tiny insects that feed on the mum plant’s leaves, buds, and flowers. They are barely visible to the naked eye and can cause significant damage if left unchecked. Thrips damage appears as silvering or bronzing of leaves, distorted growth, and deformed flowers.

To identify thrips, inspect mum leaves and flowers for small, elongated insects with fringed wings. You may also notice black specks of fecal matter on the plant or flowers that fail to open properly.

To treat a thrip infestation, start by removing heavily infested leaves or flowers. Introducing beneficial insects, such as ladybugs or lacewings, can help control thrips naturally. You can also use insecticidal soap or neem oil spray to target thrips. Repeat the treatment every few days until the infestation is eradicated.

Conclusion

Mum plants are beautiful additions to any garden, but they can fall victim to various pests that affect their health and appearance. By being aware of the most common pests that infest mum plants and knowing how to identify and treat them, you can ensure your mums remain healthy and vibrant throughout the growing season. Regular inspection, proper cultural practices, and early intervention are key to keeping these pests at bay and enjoying the full beauty of your mum plants.
