Stem Nematode Plant Care Advice

What is Stem Nematode and How Does it Affect Your Plants?

Stem nematode, also known as Ditylenchus dipsaci, is a type of microscopic worm that can infect and damage your indoor plants. These nematodes are parasitic, meaning they feed on the plant's tissues, causing harm and disrupting its growth. Stem nematode infestations can be devastating, leading to stunted growth, yellowing leaves, and even plant death if left untreated.

How Do Stem Nematodes Infect Plants?

Stem nematodes typically enter the plant through wounds or natural openings, such as the soil or water. They can also be introduced through contaminated soil, water, or infected plant material. Once inside, the nematodes migrate to the stem and leaves, where they feed on the plant's tissues and reproduce. The nematodes can also move from plant to plant through contact or by being transported by insects, water, or wind.
