Growing Asparagus from SeedsStart the seeds indoors. Early in the spring, sow single seeds in small pots meant for starting seedlings. Place the pots in full sunlight, moisten the soil daily, and keep them at a temperature of 77 degrees Fahrenheit.Lower the temperature when the seeds sprout. Once they have sprouted, they do not need to be kept as warm. Lower the temperature to 70 degrees Fahrenheit.Plant the seedlings outside. When the seedlings are about a foot tall, and the weather outside has warmed to spring, it's time to plant them outside in a nursery bed. Dig a hole about 3 inches deep to allow them to continue growing.Weed out the female plants. When the plants begin producing flowers, you'll be able to tell which are male and which are female. The male plants have large, long flowers, and the females have smaller flowers. Pull up the female plants and compost them.Transplant the male plants to the permanent bed. Let the male plants complete their growing cycle and overwinter in the nursery bed. The following spring, one year from germination, they have reached the same maturity as one-year crowns, and are ready to be transplanted to the permanent bed.
