First year w/ a square foot garden, 3rd year (though not consecutive) with a garden. The first year I planted jalapeno transplants from a local garden center - they grew and produced like crazy. The next year I tried a variety of jalapenos from seed in the same raised beds as the previous year - almost every seed sprouted, grew to about 1 inch tall, stalled and died.
This year (few years later), in a square foot garden, I planted jalapenos, bells and habaneros, all did the same thing - sprout, grow to about 1 inch, stall, die.
Should I be starting these indoors, growing them to a certain size and then transplanting? Is there something else I'm doing wrong?
