I would water the spot really well, wait a day or two, until it sort of dries out, but not completely, then dig it up in a big circle around both of them and then very carefully start removing the soil until you can find the outlines of each individual plant. And from the top, carefully start to pull them apart from one another. Then replant each of them.
