Ask Gardenerd: Lumpy Tomato Roots, Root Nematodes
A timely question came in to Ask Gardenerd this week from Catherine: "My garden went gangbusters this year but I noticed...the roots of all plants (4 tomatoes and 2 cucumber plants) were bumpy, like they had grown lumps all over. I read something about 'root nematodes' but the link wasn't very informative about what causes this, or if it is a pest or an organic condition, if I need to treat the soil before planting anything new, etc. Any thoughts…
