I'm growing baby doll dianthus from seed. The seed packet states keep in warm place. Gardening site states keep in fridge? Also, when should I transfer to garden? Many thanks.
Keeping seeds in the refrigerator is usually done to simulate winter dormancy, thus encouraging better germination. To be honest, I would always prefer gardeners' experience to directions on packaging; I've seen too many labels that are less than accurate. Perhaps when they say "warm place," they mean for actually germinating the seeds. Here's an article that may contain a few tips you can use: https://www.gardeningknowhow.com/ornamental/flowers/dianthus/growing-dianthus-plants.htm
