My Eastern Ontario garden is still under snow.
But I just started my begonias last week. I have a seed tray under a heating mat, and begonias are notoriously slow!
Over the next 3 weeks, I'll be seeding petunias, alyssum, and crystal palace. I'll have them under one long grow light.
When the snow goes, I'll put up my portable greenhouse. (It goes up and takes down like a tent.) I put it up very close to my
front door, do it's easy to carry plants back and forth. Then the seeding trays go out to the greenhouse during the day, and I'll carry
them in at night. Then I'll be seeding cucumbers, pumpkins, zucchini, and 6 different kinds of tomatoes.
