Fill a nursery flat with a seed germinating mix. Moisten the mix by with water from a spray bottle.
Place Chinese chive seeds on top of the germinating mix. Add 1/4-inch-thick layer of germinating mix over the seeds. Gently press down the germinating mix with the back of a spoon or a thumb. Cover the flat with the lid and place in warm, well-lit location.
Mist with water as needed to keep moistened as the seeds germinate. The mix should remain wet to the touch but not soggy. Wait approximately four weeks for the seedlings to sprout and grow before transferring into a planter.
Fill a well-draining planter of your choice with soil that has a pH level of 6.0 to 7.0. Dig out small holes large enough to accommodate the root system of the seedlings. Carefully remove the chives from the nursery flat and transfer into the new planter. Space multiple plants in the same container at least 6 inches apart. Gently press the soil to brace the plants.
Position the planter in a location that receives at least six hours of sunlight daily. Water as needed to keep the soil moist. After the flowers have fully bloomed, cut them off to avoid seeding.
