When to start winter sowing in zone 6a?
Most seeds that require stratification need several months of cold, moist conditions to break dormancy. Winter sowing in early to mid-February is early enough in my zone 6a climate. In the very early Spring (end of January to March) you can sow hardy annual seeds. These are seeds that will produce plants that are tolerant of frost – they’ll put on strong deep roots all winter long and produce flowers from June until the first frosts (where I live in Surrey that happens in early November).
