I just learned this past weekend from a gardening program on the radio from a tomato expert that the reason why the leaves turn yellow is when the tomatoes start to turn red and ripen they release ethylene gas which causes a leaves to turn yellow. (07/31/2007)

Tomato Plants with Yellow Leaves

Now this may sound bizarre, yet one evening I watched a gardening program, where cigarettes were added to the soil! I tried this, as up until that point my plants were slow to grow and dying down the bottom of the plant, so I planted about 20 butts from my father: ash, filter and all, in each of my potted plants, at first I really thought I had killed them, they had an immediate reaction, the already sick bottom leaves died off yet then each of the plants sprouted, growing 30 cm in a couple of weeks and their fruit are plump and healthy. The sickly leaf condition hasn't reappeared and I have found one benefit to my father's chain smoking so I am happy.
