Light : This fern likes partial shade. So a bright room with a bit of shade would probably do him best.
Water: You can keep the soil of your Asparagus Fern moist, just don’t let him stand in water. You don’t need to water him as much in the winter, but just don’t let him dry out completely.
Humidity: Just like any fern this guy loves humidity. You can put him the kitchen or bathroom, group him with some other plants or make sure he gets some misting.
Temperature: Your Asparagus Fern will be fine in normal household temperature.
Food: During the growing season (spring/summer) you can fertilise your fern weekly with weak solution. I would also suggest starting at ¼ of the recommended amount and maybe work your way up to half if needs be.
Toxicity: If you’re lucky enough that your Asparagus Fern grows berries then they are inedible.
