Place the pot with the yarrow seeds in a sunny and warm location. The seeds should germinate in 14 to 21 days, depending on the conditions. You can speed up the germination by covering the top of the pot with plastic wrap to keep in moisture and heat. Remove the plastic wrap once the seeds have sprouted.
