Tomato Plants have Root Nodes
Hi! I have eight tomato plants. Most of them are really healthy. One of them that is planted in a very large pot I notice some strange look things on the main root. I don't know what to call them other than "nodes". I have enclosed several pictures for you to see them.
Also two of my plants the leave seem to be curling up on them. They are still growing and otherwise seem healthy. Is there something wrong with them? Pictures of them are also enclosed.
Help please. Live on the coast of Oregon.
