Stem Canker Plant Care Advice

What is Stem Canker and How to Identify it?

Stem canker is a common issue that affects many indoor plants, causing significant damage and stress to the plant. It is a fungal disease that targets the stem of the plant, causing it to decay and eventually kill the plant. Identifying stem canker early on is crucial to prevent its spread and save your plant. So, how do you identify stem canker?

Look out for the following signs:

• Lesions or cankers on the stem, which appear as dark, sunken areas
• Soft, mushy, or rotting stem tissue
• Dieback of the stem or branches
• Yellowing or wilting of the leaves
• A foul or sour smell emanating from the affected area

If you notice any of these signs, it's essential to take action immediately to prevent the disease from spreading.

Causes of Stem Canker

Stem canker is typically caused by fungal pathogens, such as Botryosphaeria, Fusarium, and Phomopsis. These fungi thrive in moist environments and can enter the plant through wounds, cuts, or natural openings. Other factors that contribute to the development of stem canker include:

• Overwatering, which creates an ideal environment for fungal growth
• Poor air circulation, which prevents the plant from drying out
• High humidity, which fosters fungal growth
• Inadequate light, which weakens the plant's immune system
• Physical damage to the stem, which provides an entry point for fungi

By understanding the causes of stem canker, you can take proactive steps to prevent it from occurring in the first place.
