NOTE: In this article, Cardboard palm and Zamia furfuracea may be used interchangeably; in fact, Zamia furfuracea is the botanical name for Cardboard palm.
The cardboard palm is not a palm tree, despite its common name. Its name is derived from its growth habit, which is similar to that of palms. Pinnate leaves are the same as a palm frond that you would find on a lipstick palm.
The plant has bright green leaflets with a fuzzy feel similar to cardboard. The best time to plant it is in the spring. Outside of its tropical growing zones, it is commonly kept as a houseplant.
Why does my Zamia furfuracea roots have rot?
If left untreated, root rot on your Cardboard palm (Zamia furfuracea) can be fatal. For this reason, if the symptoms appear, we highly advise that you adhere to our recommendations to keep your plant alive: Blackened and softened roots.
Why does my Cardboard palm have gray mold spots?
Gray mold spots are a type of fungus that is found a lot in flowers, and spreads quite rapidly. If you notice brown (or gray) spots, it is probably this fungus. Don’t ignore these symptoms, as they may end up killing your plant.
The solution is quite logical when you know the cause of the problem. Most of the time, it is due to overwater of the Zamia furfuracea. We advise you to remove the infected parts of the plant, cut off the infected roots and leaves, then repot your plant using sterile potting soil and a clean pot.
Why does my Cardboard palm have leaf spots?
This type of disease is one of the most frustrating for Cardboard palm owners, we give you all the leads to spot and save your plants that present symptoms such as leaves that suddenly change color, or wilt/droop.
Why are my Cardboard palm leaves turning yellow?
Yellowing leaves are arguably the most prevalent issue in the gardening world. Overwatering or a lack of nutrients are the 2 main causes of this issue.
Reduce your watering frequency when you fear your plants are being overwatered, and follow these steps to determine whether they may be lacking in nutrients:
Here are some signs of yellowing caused by the many deficiencies on the Zamia furfuracea in question:
- 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.
- Sulfur deficiency starts with the newest leaves, turning them yellow throughout.
- Leaf edges turning bright yellow but inside leaf remaining green are signs of potassium insufficiency. The symptoms first appear on older leaves, and the leaf edges quickly become dark.
- A broad yellowing indicates a nitrogen deficiency. Yellowing starts with older, inner leaves. Yellowing spreads as it advances, eventually touching new leaves as well.
You only need to respond to the signs mentioned above. A gardening store expert will be able to provide you advice on how to purchase a specific soil to treat a potassium or nitrogen deficiency. Additionally, you can reduce how often you water your plants.
Is my Cardboard palm sunburned?
It is quite easy to find out if your Cardboard palm (Zamia furfuracea) has been burned by the sun. Just like on us, your plant will change color in this case, it will start to turn yellow or white.
As we saw above, if your Cardboard palm receives too much water or not enough light, the leaves may also change color.
However, there is a way to tell if it is sunburn; look at the bottom of the yellow leaves, the ones that have a shaded area closer to the root, if this area stays greener, it is probably sunburned, not something else.
Why are my Cardboard palm 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 Zamia furfuracea in direct sunlight?
No! Don’t leave your Zamia furfuracea (or Cardboard palm) in the sun if it displays the symptoms mentioned above; that’s why it’s in such a bad situation.
As explained in the paragraph above, the solution is simple, just place your Cardboard palm in a place where the light does not reach it directly, in this way and with a correct watering, your plant should resume its life rather quickly.
Why are my Zamia furfuracea leaves drooping or wilting ?
This typically occurs when your Zamia furfuracea gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.
An easy way to know if your Zamia furfuracea is lacking water is to under-weigh its pot, if it looks light, it means that the soil and the roots are probably quite dry, and therefore need water!
In order to ensure that the roots of your plant receive the water’s benefits, you must first moisten the soil in the container if it is absolutely dry. One common error is to immediately drown the Cardboard palm after a dry period in the belief that it requires 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 Zamia furfuracea
Water is necessary for your plant to live, but timing and amount of watering must be balanced. Overwatering could have disastrous effects on your own name, as we already mentioned.
You can tell if your plant needs water by touching the soil; if it still feels damp, it’s usually preferable to wait a few more days.
Always keep temperatures stable
It is also a good idea to keep your Zamia furfuracea at a stable temperature (especially if it is kept indoors!). At GreenShack, we generally recommend staying in the 65 and 85 degrees F range. Of course, do not place your Zamia furfuracea near a source of hot (or cold) air such as A/C units, radiators or the like.
Keep your Cardboard palm Dust-Free
This one relates to indoor plants. Just like your furniture, dust collects on the leaves of your indoor plants. The issue is that this can block the photosynthesis process from starting, which would cause the plants to gradually lose their color.
This would also make the pests happy, a real descent into hell for your Cardboard palm.
To remove the dust from the leaves of your plant, take a microfiber cloth and gently rub the leaves. You can wet the cloth to make it easier to remove the dust, but never use corrosive products (such as 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.
You can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the interim if your pots don’t already have holes in them. This will help to form a channel so that the water doesn’t pool there for too long (preventing the rot of the roots!).
