I would now. When I got to that point, i just cut the stems. The sooner you do it, the sooner your chosen plants will get all of the nutrients and water rather than having to share

i recently let them get bigger , and just gently pulled up the one i didn’t care about , and gently stuck it in some more soil , and it seems to have survived if you want xtra plants , if not can cull

I like experimenting, this year I very gently pulled my pairs apart and repotted them into their second pots. So far almost all of them are doing well. I am going for quantity of plants however so if you’re just keeping a few id do what the above guy said.

I do it early. To me, it’s just insurance against seeds that either don’t germinate or when the seed leaves get permanently stuck in the seed coat. The longer that there are two plants inside that tiny starter cell, the less water and nutrients are available for the plant that you pick to keep. One could say, keep the other seedlings in case one of them gets sick and dies randomly, but if one seedling in the cell dies of disease or overwatering or something, chances are that the other seedlings will be affected too.
