Root Problem (Root Knot Nematodes?)

[mwancho]

Hello,

I planted my first garden in our (new to us) house this past April. I have been very pleased with the results and excited by everything there is to learn. My favorite and first to produce fruit was a Taxi. The first tomato I pulled off was a pretty good size, the ones that followed weren't nearly as large. The Taxi has since died off (I took some experimental sucker cuttings which are rooting in water at the moment) and I pulled it. Upon inspection, I found knotty roots. I'm wondering if this could be a result of root knot nematodes. Another interesting tidbit: I found an old journal entry from the previous owners at one point which stated something about turning the tomato beds and there being no nematodes that year. If this is in fact root knot nematodes, I'll plan to innoculate this bed next summer using the solar method.

Your expert advice is greatly appreciated.
