Blood meal works, too, but it is high in nitrogen and therefor is not a good additive to use around peppers. Peppers can grow and leaf-out like crazy with lots of nitrogen, but that inhibits budding and fruiting. Some of the people that show off huge pepper plants are probably over-using nitrogen. That causes over-foliation and inhibits ripening of the peppers. My season is so short that I can't afford to make that kind of mistake.
