This is the kind of winter that was giving me less than 5% germination
planting seeds outdoors, motivating me to find another way.
Seeds got a lot of chilling in December - temperatures down to 12oF for
about a week, well below freezing most of the month. Starting a few
days ago and for the rest of the week, lows will be in the 40s, highs in
the upper 50s & 60s, light showers off and on - perfect germination
weather. I found one seedling already up about an inch yesterday.
January typically has the coldest temperatures of the winter - most
seedlings that germinate outdoors this early are likely to be killed,
especially if temperatures do the usual and drop abruptly to the teens
again.
This is when the strategy of taking either a 3 month long or two
separate chilling cycles before germination is a good plan for a seed!
I'm afraid all those easy to germinate seeds that don't need chilling
and that didn't get burrito'd are done for.
