Dying from the bottom up - what am I doing wrong?
The leaves turn yellow; they don't fall off, but I usually pick them off so the plant looks better. This has happened to every tomato plant I've ever grown, both in the ground and in pots, and in various climates. So the problem must be me.
I usually get a pretty good crop of fruit, but the plants lose most of their leaves and quit producing earlier than the garden books say they should. I live in S. CA, so I would like to get fruit well into fall, maybe early winter. Any thoughts?
