How long for heirloom seeds to start sprouting?
I just started my patio garden one week ago, and I have five different seeds that I've created "greenhouses" for to get them started. Currently, only one of them (the siberian kale) has began sprouting. The seeds are older so I'm not sure if some of them are bad. How long does it take before they sprout for me to know if they are duds or not?
