NOTE: The terms Maidenhair fern and Adiantum raddianum are identical in this text; in reality, Adiantum raddianum is Maidenhair fern’s biological word.
There are delicate fan-shaped leaf segments that are clustered on black stems, and their leaves are smaller than other types of ferns. In addition to being one of the most popular houseplants, the maidenhair fern can also be found in nature, growing in places where other plants typically don’t, like on rock walls and in between rock fissures where the water from water seepage keeps them alive.
They are considered a slow-growing fern, taking up to three years to reach their full mature size, even though they are visually stunning throughout all stages of their growth. If you live in the right USDA zone, you can plant the fern outdoors any time during the year.
Why does my Adiantum raddianum roots have rot?
Root rot on your Maidenhair fern (Adiantum raddianum) can be dangerous if left untreated. In order to keep your plant alive, we strongly suggest that you follow our advice if the signs start to show: blackened and mushy roots.
Why does my Maidenhair fern have gray mold spots?
A particular fungus that frequently affects flowers and spreads quickly is known as gray mold spots. This fungus is most likely to blame if you see any brown (or gray) spots. Don’t ignore these signs because doing so could cause your plant to die.
The answer is obvious once you recognize the cause of the problem. Most frequently, it results from the Adiantum raddianum being overwatered. We strongly advise you to remove the damaged plant parts, cut off the diseased roots and leaves, and then repot your plant in a new container with sterile potting soil.
Why does my Maidenhair fern have leaf spots?
If your plants exhibit symptoms like rapid color changes in the leaves or leaves that wilt or droop, we give you all the information you need to recognize them and rescue your plants. For owners of Maidenhair fern, this kind of illness is among the most distressing.
Why are my Maidenhair fern leaves turning yellow?
This is probably the most common problem in the gardening world, yellowing leaves. There are 2 main reasons for this phenomenon, overwatering, or a lack of nutrients.
When it’s overwatering, simply reduce your watering frequency, and if you think it’s a nutrient deficiency, here’s how to check it:
Each deficiency produces a different yellowing on the Adiantum raddianum in question, here’s how to spot them:
- Yellow patches between leaf veins on elder leaves are the first sign of magnesium shortage. Veins continue to be green while the leaf’s core turns yellow. The leaf’s edges yellow last.
- Yellowing between leaf veins is another sign of iron shortage, but young leaves on plant tops and branch tips are initially affected.
- The newest leaves are first affected by sulfur deficiency, rendering them completely yellow.
- Insufficient potassium causes the leaf edges to turn brilliant yellow while the interior of the leaf stays green. Older leaves show the symptoms initially, and the leaf edges quickly darken.
- Nitrogen deficiency shows up as a general yellowing. Older, inner leaves turn yellow first. As it progresses, yellowing moves outward, eventually reaching young leaves, too.
According to the symptoms mentioned above, you just have to act accordingly. You can reduce your watering frequency, or fix a deficiency in Potassium, or Nitrogen, for that, you just have to buy a special soil for your deficiency, a consultant in a gardening store will know perfectly well how to inform you.
Is my Maidenhair fern sunburned?
You can easily tell if your Maidenhair fern (your Adiantum raddianum) has a sunburn. In this case, your plant will change color, starting to turn yellow or white, much like it does on us.
The leaves of your Maidenhair fern can also change color in case it gets too much water or not enough light, as we saw above.
The bottom of the yellow leaves with a shaded area closer to the base can be examined to determine if they have been sunburned. If this part remains greener, the yellow leaf is most likely sunburned and not something else.
Why are my Maidenhair fern leaves turning brown?
A plant’s browning leaves are typically a symptom that it has been sunburned and has been exposed to excessive amounts of direct sunlight. Don’t worry; your plant probably won’t perish as a result, but its growth will be negatively impacted.
Should I leave my Adiantum raddianum in direct sunlight?
No! If your Adiantum raddianum (or Maidenhair fern) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Maidenhair fern is in such a state!
The remedy, as said in the paragraph above, is simple: just move your plant’s Maidenhair fern out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.
Why are my Adiantum raddianum leaves drooping or wilting ?
In most cases, this happens when your Adiantum raddianum lacks water. This is especially the case for large plants, naturally they need more water than others.
Whether your Adiantum raddianum plant’s pot appears light, the soil and roots are likely fairly dry and need water, so you can readily tell if it needs to be hydrated.
If the soil in your plant’s pot is completely dry, you will need to start by moistening it so that the roots will also benefit from the water. A common mistake is to drown the Maidenhair fern right after a dry period thinking that it needs a lot of water.
This is the case, but giving too much water at once is the best way to finish it off, you should actually water the soil normally, resuming a quiet watering rhythm.
Caring Tips for Adiantum raddianum
Water is essential to the survival of your plant, however, it is important to balance the rate of watering. As we explained above, overwatering could have fatal consequences for your Adiantum raddianum.
The best way to know if your plant needs water or not is to touch the soil, if you feel it is still wet, it is probably a good idea to wait a few more days.
Always keep temperatures stable
Maintaining a consistent temperature for your Adiantum raddianum is also a good idea, especially if it is kept indoors. At GreenShack, we typically advise reserving a temperature between 65 and 85 degrees F. Of course, avoid positioning your Adiantum raddianum close to air conditioners, radiators, or other sources of hot or cold air.
Keep your Maidenhair fern Dust-Free
This one is about houseplants. Your indoor plants’ leaves get dusty just like your furniture does. The problem is that this might prevent photosynthesis from beginning, which would result in the plants gradually losing their color.
This would be a true journey into hell for your Maidenhair fern and would also satisfy the pests.
To remove the dust, gently rub the plant’s leaves with a microfiber cloth. Dust can be removed more easily with a damp cloth, but stay away from corrosive substances like rubbing alcohol!
Keep drainage in mind
If you have a tendency to overwater, you need to keep an eye on your drainage, we advise you to opt for a pot with drainage holes if it is not already the case and a saucer.
If your pots don’t already have holes in them, you can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the meantime. This will assist in creating a channel and keep the water from pooling there for an extended period of time, protecting the roots from decay.
