Last year, grew some jalapenos. They were relatively mild. Could eat raw, no eye tearing or tremendous urge to drink liquids resulted. This year, same seed, eyes tear up, scalp sweats, lots of liquids after eating this year's.
Biggest differences in the garden. Lotsa rain this spring and beginning summer. Added sandy loam to the raised bed garden in winter. Jalapenos longer on the plant before beginning to change color this year. Like to pick em just before the color change sets in. Dave
