Let’s just be clear here, right from the start: I’ve killed A LOT of Maidenhair Ferns over the past 5 or so years. That doesn’t stop me from loving them. Since my very first dalliance with house plants, these little soft delicate beauties have been at the top of my list of favourites. The issue is, of course, that they are difficult to keep alive – and I don’t just mean after a few years. I have lost Maidenhairs within weeks of getting them home from the garden centre. Weeks, people. Not even months. Sad times.
In fact, after repeatedly having these lovely specimens dying on me, I had to take some time off from buying them because I had so much guilt associated with them. However, a couple of months ago, I decided that I was going to give it one last try. And I decided – finally! – to do some proper research to ensure that I was giving this pretty girl a chance to really flourish.
In my research, I came across 6 different tips for keeping your maidenhair fern alive and I realised why my maidenhair ferns kept dying on me in the past. Armed with this new-found knowledge, I’ve applied all of these points religiously to my own plant and guess what? I’ve not had even one shrivelled leaf, not one hint of dryness and she has continued to look just as good as it did when I brought her home. Eureka.
So I figured today, I’d pass on what I’ve learned about keeping maidenhair ferns alive. This is not for the faint of heart, either. If you’re looking for easy-to-care-for house plants because you tend to neglect your plant babies, this may not be the best one to start off with. It takes commitment and constant attention. Maidenhair ferns are DIVAS of the highest order. But if you are ready to take the plunge into Beyonce-level plant maintenance, then do read on…
The delicate maidenhair fern is beloved for its lacy, delicate fronds, but this beauty comes at a price – its fussy care requirements. If something is not just right, you’ll quickly see the consequences as the fronds start turning ugly shades of yellow and brown.
Not to worry! Brown fronds don’t necessarily spell doom for your maidenhair fern. This article will explore the most common reasons these ferns get brown leaves and how you can bring yours back to vibrant health.
Lighting Issues
Light problems are the number one cause of maidenhair ferns declining. This plant needs bright, indirect light to thrive. Direct hot sunlight will scorch the delicate leaves, causing them to brown and shrivel up.
On the other hand, too little light leads to slow growth. When a maidenhair fern doesn’t get enough sun, the older inner fronds turn brown and drop off faster than new ones can grow.
The solution is to place your maidenhair fern in an east or north facing window. An east window provides gentle morning sun, while a north window gives ample bright light without direct rays. Rotate the plant weekly so all sides get even light exposure.
If you don’t have a suitable window, consider supplementing with a grow light. LED plant lights are affordable and last for years. Position the light 12-18 inches above your fern and set the timer for 12-14 hours per day.
Watering Issues
Ferns prefer evenly moist soil at all times. If the soil dries out completely the fronds will quickly shrivel up and die. Brown leaf tips are one sign the plant needs more frequent watering.
On the flip side soggy soil leads to root rot and brown leaves. Stunted new growth indicates you need to back off on watering. The key is finding the sweet spot between too wet and too dry.
Aim to keep the soil slightly moist but never saturated. Check it daily by sticking your finger 1 inch into the soil. Water whenever the top layer feels dry. Pour enough water until it drains from the bottom, then dump out any excess from the saucer.
Low Humidity
The humid forests where maidenhair ferns originate are far different from our dry, heated homes. Low humidity stresses the plant, resulting in brown leaf edges that progress to entirely crispy fronds.
Use a humidifier in the room with your fern and aim for 40-60% humidity. Also place the pot on a pebble tray filled with water, but keep the water below the bottom of the pot. This evaporating water increases humidity right around the plant.
Misting leaves helps temporarily but doesn’t raise overall humidity. Grouping plants together creates a beneficial microclimate.
Temperature Extremes
Ferns prefer temperatures between 60-75°F and can suffer if it gets too hot or cold. Hot air from heating vents or drafty windows has a drying effect. The plant responds by turning brown at the tips and margins.
Move maidenhair ferns away from hot and cold air sources. Keep daytime temps between 65-75°F and nights above 55°F. Consider a space heater or cooling fan to maintain optimal conditions.
Overcrowding
When a maidenhair fern outgrows its pot, roots compete for space and nutrients. Inner fronds yellow and drop off when crowded. Growth slows down and remaining leaves often turn brown.
Repot in a larger container every 2-3 years or whenever roots fill the pot. Trim off any dead leaves, then gently loosen the root ball and place it in fresh potting mix. This gives your plant room to grow.
Poor Air Circulation
Stagnant air encourages fungal leaf spot diseases. These infections cause translucent brown spots that can spread to kill the entire frond. Proper airflow is key to preventing disease issues.
Make sure fans are not blowing directly on your fern. Gentle circulation mimicking a light breeze is ideal. Move plants away from stagnant corners and prune off any infected fronds.
Improper Fertilizing
Too much fertilizer can burn delicate maidenhair foliage and cause leaf tips to turn brown. On the other hand, lack of nutrients leads to slow growth and inner fronds dying off.
Use a balanced liquid fertilizer at half strength every 2-4 weeks during spring and summer. Ease off in winter, but feed monthly if your fern is still actively growing. Flush the soil monthly to prevent buildup.
Normal Leaf Drop
It’s natural for some old inner fronds to yellow and drop off over time. As long as there is new growth emerging, this is nothing to worry about. Just prune off shabby fronds to maintain an attractive appearance.
Monitor your plant to ensure leaf drop does not exceed new growth. With good care, maidenhair ferns can thrive for years. Be patient through setbacks and you can enjoy this delicate fern’s beauty.
Prevention is Key
To keep your maidenhair fern’s fronds green and lush, be vigilant about providing proper lighting, humidity, temperatures, watering, and care. Learn its preferences and inspect it frequently to catch any issues early. While maidenhair ferns may be fussy, they reward your efforts with their graceful, delicate beauty.
Tip 3: Water it when it’s dry but don’t overdo it
Keep a very close eye on your maidenhair fern’s soil. If it feels very dry to the touch or you are seeing any slight shrivelling of the leaves, you need to get some water into her pot asap. You can give the soil a good soak but ONLY if you drain it until all the water has run through – and this is why keeping it in the original pot is a good idea. The thing is, maidenhair ferns like moisture – they need it desperately and so they require the soil to be nice and moist but not sopping wet. You don’t want the roots to get bogged down in too much water. If you do, your beautiful beauty will die on you.
I find the time I need to water her varies – sometimes it’s once a week, sometimes it’s a little more depending on how warm it is. I make sure it’s nice and dry and then give it a good soak, let the excess water drain away and then I leave it until the soil feels dry again. If you don’t want to bother with the draining part, then don’t soak it through – little and often to keep the soil moist is going to be what is required. It’s a delicate balance and I find myself checking her soil nearly every day to keep on top of it.
Tip 1: Don’t touch the leaves
So this is one I had blatantly ignored in the past but could be one reason why so many have failed to flourish within my hands (literally and figuratively). You can’t touch the leaves. I know, I know, how lovely and soft they are, how the delicate fronds just feel so damn nice but resist the urge. The issue is that your hands contain natural oils and when you handle the leaves, that oil is transferred on to them, blocking up their ability to take in moisture and light from the air.
When you are handling your maidenhair, do everything you can to make sure your hands aren’t directly touching her leaves or use gloves if you must. Whatever you do, just keep your hands off her!
