Depends largely on where you live and if you start indoors or out.

@RayaHope, that’s why I specified it in the details, and not by date, but by season. I am mostly interested in how others fare with this.

Also by what plant.

I seem to have not put it that well. I want to know what and when others do. There are people locally I can consult, I am just curious about what other jellies do.

I’m trying “winter sowing” for the first time, just put them out today.

I’m just north of Orlando and start plants inside of my house any time of year, but I just do things like lemon seeds and peppers. As long as they are near a sunny window most things I’ve tried to start sprout up, I haven’t paid much attention to what time of year.

The best time in FL for starting seedlings is springtime for a lot of fruits and veggies for outside gardens. I think almost everything grows in spring here; late February, March, or April. An exception I can think of is strawberries, I very big crop near me. I think those are planted in fall and harvested in March, April, and May. We have big festivals in that March April time frame.

When the snow is off the mountain.

I grow a lot of basil to make pesto, and I grow it from seed outdoors for the challenge and fun.

And every year in May or June I say, “I should have started the seeds indoors in February!”

This year I plan to start my seeds inside in February. I am in Wisconsin, in USDA Plant Hardiness Zone 5b.
