Tomato disease - where to go from here?
Been trying to grow tomatoes in Southern California (LA area). Never had these problems in Kansas where I'm originally from, but each year the plants grow great until the first fruit sets and then start to wilt from the bottom up and eventually die. This has happened at multiple houses and in ground as well as in pots.
This year I built a raised bed and things were going great for a while then started to get the wilting. I thought it was a fungus as I've noticed a bit of powdery mildew on my squash plants. Pepper plants are doing great. Today was reading more and came across a suggestion to check and cut open the stems. Noticed some hollow stems and when cut lengthwise the telltale 'ladder' effect associated with pith necrosis. Ripped out the affected plants but don't know where to go from here, there doesn't seem to be that much info about this disease. Will my other plants be ok? Assuming in my small 8' x 4' bed I am pretty much done for tomatoes. Any people in the area had this same problem and if you've overcome it, how?
