When to Start Seeds Indoors: Month-by-Month Guide for Cold Climates (H6/H7)

Getting seed timing right in a cold climate isn't just about organisation—it's the difference between abundance and disappointment. This month-by-month guide takes you through the entire seed-starting year for zone H6/H7 and similar climates, from those first onion seeds sown around Christmas to the last broccoli starts in May. Learn when grow lights are essential, why starting too early can cause more problems than starting late, and how winter sowing outdoors can give you hardier plants without taking up precious indoor space. Whether you're chitting potatoes in February or protecting April seedlings from late frosts, this practical guide helps you work with your short growing season rather than against it.
