Without even realizing what day it was, I started introducing my female to her partner for the year. Got the okay from the vet earlier today (because of her surgery last year) and put them together. They immediately started courting each other; don't know if any actual mating happened but they were definitely thinking about it before I gave them some private time

I've got her back in her normal solo tank for the night though; neither have ever lived with another garter, and the size difference is large enough that I don't want to immediately just leave them alone for long periods.
