Growing an Elkhorn fern (Platycerium bifurcatum) indoors can feel like a rewarding adventure. These elegant, antler-shaped ferns add so much character to an apartment or home. But when it comes to watering, things can get confusing. How much water do they need? How often? Should you mist or soak? And what if you’ve overwatered? Don’t worry! With some patient learning, you can master caring for your Elkhorn fern and help it thrive.
Below, we’ll walk step-by-step through everything a beginner needs to know about watering the Elkhorn fern, as well as some secret tricks that experienced plant lovers swear by.
How Often Should You Water Elkhorn Fern (Platycerium bifurcatum)?
The Elkhorn fern does not follow a strict watering schedule. How often you water depends on your home’s humidity, temperature, and how much light your Platycerium bifurcatum gets.
- Typically, water every 7–10 days during spring and summer, when growth is fastest.
- In fall and winter, water every 2–3 weeks, since cooler, darker conditions slow the plant down.
Always check first before watering! Stick your finger into the growing medium (soil, moss, or bark) or lightly pinch the base of the plant:
- If it feels dry, it’s time to water.
- If it’s still damp, wait a few more days.
Tip: In smaller, warmer apartments, your fern might dry out more quickly. Trust what you feel, not the calendar.
How Much Water Does Platycerium bifurcatum Need?
Elkhorn ferns like a deep, thorough drink, but not to sit wet for long periods.
A good method is to soak:
1. Remove your Elkhorn fern from its spot.
2. Gently pour lukewarm water over the base until the material (moss or bark) is soaked. If your plant is mounted, use a showerhead in the sink.
3. Let it drain fully before returning it to the wall or shelf.
Or, dunk the whole root ball or mount in a bucket of water for 10–20 minutes, then lift it out and let it drip dry.
What About Misting or Spraying?
- Misting is helpful, but not enough on its own.
- Mist your Elkhorn fern between waterings, especially if the air is dry.
- Focus sprays on the shield fronds (the flat, round “leaves” at the base), but avoid daily soaking.
Does the Elkhorn Fern Need High Humidity?
- Yes, Platycerium bifurcatum loves moderate to high humidity—aim for 50% or more.
- If you live in a dry apartment, a small humidifier, grouping plants together, or placing a tray of water nearby can help.
Signs your plant wants more humidity:
- Brown, crisp edges on fronds
- Curling antler fronds
- Dull appearance
Is Elkhorn Fern Sensitive to Overwatering?
Absolutely. Perhaps the biggest risk for indoor Elkhorn ferns is overwatering. Roots can rot if they stay soggy.
If you’ve ever given too much water:
- Don’t feel bad! Most people do this at first.
- Let the plant dry out more between waterings.
- Always allow extra water to drain away (never leave the base sitting in a tray of water!).
Can Elkhorn Fern Survive Drought or Neglect?
- Platycerium bifurcatum is quite tough and can handle missing a few waterings, especially when grown on a mount instead of in a pot.
- If you forget to water, soak it well when you remember. Most Elkhorn ferns bounce back quickly!
What’s the Best Way to Water: Bottom or Top?
Top watering is recommended for most Elkhorn ferns, whether mounted or in a basket with moss. Pour water gently so it penetrates the root mass, then let it drain.
If your fern is potted in soil, you can:
1. Stand the pot in a shallow dish of water for 10 minutes (“bottom watering”); the soil will soak up what it needs.
2. Always empty any leftover water from dishes or trays afterward.
Mounted ferns do best with soaking or gentle top watering.
What to Do With Excess Water After Watering?
Never let your Elkhorn fern sit in water! After watering:
- Let the fern drip dry in the sink, shower, or over a towel for 30 minutes.
- Empty any water collected in trays or the bottom of the plant’s container.
This prevents root rot and keeps your Platycerium bifurcatum healthy.
Watering Elkhorn Fern: Summary
Taking care of an Elkhorn fern (Platycerium bifurcatum) doesn’t have to be intimidating! Water when the growing medium feels dry, provide deep drinks, and always let it drain well. Mist between waterings for extra humidity, and make sure not to overwater. With these simple steps, you’ll have a thriving, happy Elkhorn fern in your home—even if you’ve made mistakes in the past. You’ve got this!
