I finally started to get ripe tomatoes about a week ago. As you can see, there are lots more standing in line. This year, I have various sizes of red, orange and yellow tomatoes.
Every year, regardless of the bed in which I plant my tomatoes, and regardless of the variety (including varieties with an alphabet of resistance genes), the bottom leaves blacken, and the blight works its way up the plants. If growth is robust, then the plants stay ahead of the blight. If growth is slow, then the whole plant dies. I don't know what organism causes this.
