I thought that was an odd statement too.hoodat said:I take exception to the statement that organic gardeners and farmers stress their plants. I have some tomatos over 6 feet high and still growing with no sign of disease and loaded with maters. That doesn't sound like a stressed plant to me.
Just because you don't use pelleted chemical fertilizers, doesn't mean your plants aren't getting what they need. And just because you do use them doesn't mean they are getting everything they need either. It's not like they supply tilth to the soil or trace minerals. What on earth do they think plants were grown on before you could buy fertilizer in a bag? If you want to "stress" them, just stop watering them for a bit! Really, that made no sense at all. I don't find that to be a reasonable explanation for it. However, the comment is coming from a dietitian, not a botanist."By avoiding synthetic fertilizers, organic farmers put more stress on plants, and when plants experience stress, they protect themselves by producing phytochemicals," explains Alyson Mitchell, PhD, a professor of nutrition science at the University of California, Davis.
