No fern species that can extract oil?

No, ferns are commonly used in home beautification. Because of its low requirements for light and simple maintenance, it is placed as a green plant in many places.

Ferns are relatively easy to raise. Let's talk about how to raise them.

Soil: Pteridophytes like humidity and water evaporates quickly, so they can choose some soil with strong water retention to raise it. Coconut bricks and peat soil can be mixed, and the proportion of coconut bricks is about 50%. Of course, all coconut bricks can be used, but coconut bricks are not nutritious, and plants can't grow well if they are used too much.

Lighting: They don't require high lighting, and indoor flash or lighting around 1 hour every day is the best. Too much light will burn you, and no light at all will be white.

Watering: keep the principle of seeing dry and seeing wet. You may be a little wet. Take Adiantum for example. If it is too dry, the edges of the leaves will turn yellow.

Fertilization: almost no fertilization, occasionally use some compound fertilizer or sprinkle some slow-release fertilizer on the soil surface. The direction of fertilization is mainly nitrogen fertilizer, because ferns basically look at leaves.

Humidity: This is very important. Pteridophytes like humid environment. If the humidity is not enough, the leaves will dry up, then turn yellow, and in severe cases will die. Teach you a way, don't dump the beer left at home, dilute it with water and put it in the watering can. Spray the leaves of ferns with the watering can every day to improve its humidity. As long as one week, you can find full of green, a overgrown plant in your home.
