I'm new to this so bear with me! Put potatoes in the garage to chit around 2-3 weeks ago. Nothing's happening. They're sitting on trays/eggboxes, on a table, near window. They have eyes and a few have teeny little shoots (but only 1-2mm) which haven't increased in length at all. What's going on? Am I expecting too much, too quickly or could the garage be too cold. They're Charlottes and Maris Piper btw. Think I should be aiming to plant them out at the end of March - is that right? Would appreciate any advice please! TIA
