Water your fern about once a week in warm weather and once every two weeks in the winter.
Give your staghorn a thorough watering. If you have your fern mounted, you can take the entire plant with its mount down off the wall, stick it in the shower or outside, and use a hose to soak the whole thing. Once it’s dry enough, hang it back on your wall.
You need to make sure you are soaking the fronds because remember, the fronds are what take in water and nutrients, not the roots.
An important aspect of staghorn fern care that you should not forget is humidity. Since they are native to tropical regions, staghorn ferns thrive in high humidity. A humidifier is an easy way to provide humidity. Also, staghorn ferns make great bathroom plants for this reason.
You can mist your fern every few days as well, just be careful with this. Having a constantly wet fern can cause fungus or rot.
Used a balanced, liquid plant fertilizer (an NPK ratio of 10-10-10 is good for this plant). Dilute it by half once a month during the growing season (spring and summer). Water the fertilizer in as you water your fern. If your plant is mature, only fertilize it twice a year.
