Nematode: Microscopic, worm-like organisms, some beneficial to soil health, while others can be plant pests that damage roots and other parts.
Nematodes are tiny, often microscopic worms that live in the soil. While some nematodes are actually beneficial, helping to break down organic matter and release nutrients, others can be serious garden pests. These harmful nematodes feed on plant roots, causing damage that can stunt growth, make plants wilt, and even kill them.
Root-knot nematodes are a common pest nematode that causes characteristic swellings or galls on plant roots. Other types of nematodes might feed on stems, leaves, or even flowers. Because they’re so small, nematodes can be challenging to detect without a soil test. Managing nematode problems often involves a combination of strategies, including crop rotation, using resistant plant varieties, and incorporating organic matter into the soil.
