Celery Seeds

Get rid of nematodes such as roundworm or eelworm. These pests can cause malformed plants with stunted, yellowing leaves. In the worst cases, leaves will wilt in a single day and the roots will become infected. The best option is to plant resistant varieties of apple, bean, carrot, celery, cucumber or onion. Otherwise, increase the organic matter in your soil. Compost contains predacious fungi and fatty acids that are toxic to nematodes. Remember to disinfect any tools that you have used in infected soil.
