Interpreting "As soon as the soil can be worked"
I m sure you have all read that sentence on seed packages. I am gardening in Zone 5, where I have snowdrops in my front garden, snow, ice, and water in my back garden, and the temps. dipping below zero most nights. I want to start my multiplier onions, but I want to have a more definitive indicator than "As soon as the soil can be worked". I just finished digging violet tubers out of the ground, which is just mud. Must the soil be dry and pliable? What other indicator do you use?
