How to Identify and Treat

Updated: February 15, 2023

Dracaena corn plants are popular indoor plants that are easy to care for and add a touch of greenery to any space. However, like all plants, they are susceptible to diseases that can harm their growth and appearance. In this article, we will discuss some common Dracaena corn plant diseases, how to identify them, and most importantly, how to treat them.

Leaf Spot

Leaf spot is one of the most common diseases affecting Dracaena corn plants. It is caused by a fungus that thrives in warm and humid environments. The symptoms of leaf spot include dark spots on the leaves that gradually enlarge and turn yellow or brown. In severe cases, the leaves may fall off.

To treat leaf spot, remove the affected leaves and ensure that the plant is not overcrowded. Avoid getting water on the leaves as the fungus thrives in moist conditions. Fungicides can also be used to control the spread of leaf spot.

Root Rot

Root rot is caused by overwatering and poor drainage. The roots become waterlogged, which leads to their decay. The symptoms of root rot include yellowing leaves, wilting, and stunted growth.

To treat root rot, remove the plant from its pot and gently wash off the soil from the roots. Cut off any brown or mushy roots and replant the plant in fresh soil with good drainage. Ensure that you do not overwater the plant in the future.

Spider Mites

Spider mites are small pests that suck sap from the leaves of Dracaena corn plants. They thrive in dry and warm conditions and can rapidly multiply if left unchecked. The symptoms of spider mites include tiny webs on the undersides of leaves, yellowing or mottled leaves, and stunted growth.

To treat spider mites, spray the plant with a mixture of water and dish soap. You can also use insecticidal soap or neem oil to control the spread of spider mites.

Mealybugs

Mealybugs are another common pest that can affect Dracaena corn plants. They are small, white insects that suck sap from the leaves and stems. The symptoms of mealybugs include a sticky residue on the leaves, yellowing leaves, and stunted growth.

To treat mealybugs, wash the plant with a mixture of water and dish soap. You can also use alcohol or insecticidal soap to control the spread of mealybugs.
