Like Deb, I use the winter to update databases and planning out the garden beds for the coming Spring. In mid January I go through my seed catalog and decide what I want to plant then find the seeds and put them in a box. I always start my seeds indoors on heating pads starting the last week in January .. the slowest germinators first. If I need to order seeds then I usually do it in February.
This coming year is going to be different. I'm putting my house on the market in Spring and moving probably to Greenville, SC. l haven't made up my mind yet if I'm going to be starting any seeds in January .. probably a few but only a fraction of the number I usually start.
