How to Propagate Asparagus Ferns From Seeds
The asparagus fern is a South African perennial evergreen hardy to USDA zones 9B through 11. Although its feathery green foliage might remind you of ferns you've seen, this plant isn't related to them. Instead, it's in the asparagus family. Propagating asparagus ferns from seeds is a simple matter. Since they develop invasive tuberous roots that are hard to control, it's best to grow them in a pot. Does this Spark an idea?

Water the soil until the surface feels evenly moist and water runs out of the pot's drainage holes. Apply more water every time the soil surface begins to dry to prevent the embryo from dying.

Place the container in bright indirect light, where the temperature stays at 77 degrees Fahrenheit. If this option isn't available, buy a propagating mat with a thermostat. Plug it in, set the temperature and place your seeded planter on it until germination. Cover the pot with a piece of clear plastic film to retain heat and moisture.

Harden your new plant off to the outdoors. Over the course of a week, leave it outside for increasingly longer periods, also gradually exposing it to more sunlight. Raise your asparagus fern outside for the summer, and take it into the house in early fall. In the winter, keep the plant where you can maintain the temperature at 50 degrees Fahrenheit or higher.
