Nematodes are small worm-like parasites that can live in soil, water, or the animals they use as hosts. Despite their small size, they truly can be menaces. As their name hints, they have something to do with the roots; however, in this case, "to do" means "wounding." Interestingly, Nematodes aren't as deadly as secondary infections. Another problem with this disease is that it doesn't have some prominent symptoms that can distinguish it from other diseases.

Signs of damage
- General weakening. If you notice that your plant is wilting, it might be or not be this disease, but it is definitely worth your attention.
- Yellowish foliage. It hints that something is off with the plant's health.
- Reduced growth. Another basic symptom of a plant's bad condition.
- Swelling of the roots. The most obvious way to identify this disease is to look at the roots. However, when the roots are visibly affected, it is not the first stage of the disease.
How to prevent
Healthy soil is key to success because Nematodes won't likely appear in such an environment. Another good piece of advice is to keep weeds under control because they mostly reproduce on the common weeds. So long story short, you need to minimize the possibility of this disease by keeping soil and other plants healthy.
Heal
Nematicides are available, but they are not so widely used because it is not so easy to find them. However, organic versions of it are more available. One is based on the soap bark root, and another one is geraniol. It is worth mentioning that not all Nematodes are harmful; some are beneficial, but these nematicides will kill both healthy and harmful ones. Azadirachtin products can also be helpful because they are extracted from neem oil, an almost universal remedy.
