The use of tree spikes will take the guesswork out of fertilizing. Here is what I recommend for 
fertilizing your Cardboard Palm.Â
I recommend using Jobes Organics fertilizer spikes.
They are easy to use and last for 2-3 months.Â
They are designed for container-grown citrus.
Using 2 spikes for a 12-inch pot or 3 for an 18-inch pot takes the guesswork out of fertilizing.
They provide a 3-5-5 fertilizer blend along with micronutrients and beneficial bacteria.
 Pot Size
Choosing the right pot size is essential for the healthy growth of your cardboard palm.
A pot that is too small can restrict root growth, while one that is too large can hold onto too much moisture, causing root rot.
In this section, we’ll go over the basics of choosing the right pot size for your cardboard palm and why it’s important.Â
Choosing the right pot size for your cardboard palm
Choosing the right pot size is important to keep your cardboard palm happy and healthy.
A pot that is too small can restrict the growth of the plant’s roots and cause the palm to become root-bound, leading to stunted growth and wilting.
On the other hand, a pot that is too large can hold too much moisture, leading to root rot and other issues. It’s essential to find the perfect balance for your plant’s pot size.
Signs that your plant has outgrown its pot
Although they are slow-growing plants they will eventually outgrow their pots.
If your cardboard palm has outgrown its pot, you may notice a few signs.
The most obvious sign is when the roots start to come out of the drainage holes at the bottom of the pot.
Another sign is when the soil dries out quickly, even after watering. You may also notice slow growth or yellowing of leaves, which can indicate a lack of space for the roots.
Repotting:
If you’ve noticed that your cardboard palm is outgrowing its current pot or the soil seems too compacted, it might be time to repot your plant.
Repotting your cardboard palm can help provide it with more space to grow and thrive, as well as fresh soil with the nutrients it needs.
In this section, we’ll cover the importance of choosing the right pot size, signs that your plant has outgrown its pot, and how to properly repot your cardboard palm to keep it healthy and happy.
How often to repot your cardboard palm:
Cardboard palms generally need to be repotted every two to three years, or when they outgrow their current pot.
If you notice that your plant’s roots are growing out of the drainage holes or the soil is compacted and not draining well, it may be time to repot.
Early spring is a good time to repot before the growing cycle starts up again.
Signs that your plant needs to be repotted:
There are several signs that your cardboard cycad may need to be repotted.
These include roots growing out of the drainage holes, slow growth or stunted growth, soil that dries out quickly, or leaves that are yellowing or wilting.
Step-by-step instructions for repotting:
• Choose a pot that is one size larger than the current pot, with drainage holes.
• Fill the bottom of the new pot with fresh potting soil, making a small mound in the center.
• Gently remove the plant from its current pot, taking care not to damage the roots.
• Loosen any compacted soil from the roots and trim any dead or damaged roots.
• Place the plant in the new pot, making sure it sits at the same level as before.
Add fresh potting soil around the roots, gently firming it in place with your fingers.
• Water the plant thoroughly and place it in a bright location, out of direct sunlight.
Temperature and Humidity Requirements
Cardboard palms prefer warm, humid environments. The ideal preferred temperature range is from 60-80°F (15-27°C).
Maintain humidity levels of 50-60% by placing a humidifier nearby or misting the leaves regularly.
Watering and Fertilization Tips
Water your cardboard palm when the top inch of soil feels dry. Be careful not to overwater, as the plant is susceptible to root rot.
Fertilize your cardboard palm with a balanced, slow-release fertilizer every 2-3 months during the growing season.
Pruning and Propagation Tips
Prune away yellow or brown leaves with sharp, clean scissors or pruning shears.
To propagate your cardboard palm, remove offsets from the base of the plant and plant them in a well-draining potting mix.

In this section, we’ll go over some of the most common problems that you might encounter when caring for your Cardboard Palm, and we’ll give you some tips on how to fix them.
From yellowing fronds to pests and diseases, we’ve got all the information you need to keep your Cardboard Palm healthy and happy.
Yellowing or browning of leaves:
If you notice that the fronds of your Cardboard Palm are turning yellow or brown, this could be a sign of several issues.
One of the most common causes is overwatering.
Cardboard Palms prefer well-draining soil, and too much water can lead to root rot, which can cause the fronds to yellow and wilt.
To fix this issue, make sure that you are not overwatering your plant, and consider repotting it in well-draining soil.
Drooping or wilting of the plant:
If your Cardboard Palm is drooping or wilting, this could be a sign of underwatering.
Cardboard Palms prefer soil that is evenly moist, but not waterlogged. If the soil is too dry, the plant will start to wilt and droop.
To fix this issue, water your plant more frequently, and consider misting the fronds to increase humidity levels.
Stunted growth or lack of growth:
If your Cardboard Palm is not growing or growing very slowly, this could be a sign of a lack of nutrients.
The Cardboard Palm plant requires regular fertilization to thrive, and if they are not receiving enough nutrients, it may not grow properly.
To fix this issue, consider fertilizing your plant with a balanced fertilizer every few months.
Other issues and their causes:
Other issues that you may encounter when caring for your Cardboard plant include pest infestations, such as spider mites or mealybugs, as well as fungal or bacterial diseases.
These issues can be caused by poor growing conditions, such as low humidity or poor air circulation.

Common Indoor Plant Pests and How to Treat Them
Even tough plants like Cardboard Palm can run into pest problems indoors, especially when airflow is poor or humidity is low. Catching pests early makes treatment much easier and helps prevent long-term damage.
Here are the most common indoor plant pests to watch for and how to deal with them.
Spider Mites
Spider mites are tiny sap-sucking pests that often cause pale speckling, yellowing leaves, and fine webbing between stems or leaflets. They thrive in dry indoor air.
Treat them by rinsing the foliage, increasing humidity, and applying neem oil or insecticidal soap. Repeat treatments every few days if needed.
Mealybugs
Mealybugs look like small white cottony clusters and often hide where leaves meet stems. They weaken plants by feeding on sap and can cause leaf yellowing or sticky residue.
Remove them with rubbing alcohol on a cotton swab, then follow up with insecticidal soap if the infestation is larger.
Scale Insects
Scale insects attach themselves to stems and leaves and appear as small brown or tan bumps. They can be easy to miss until growth slows or leaves start yellowing.
Scrape them off gently or use rubbing alcohol and follow with neem oil for better control.
Aphids
Aphids are soft-bodied pests that cluster on new growth and can cause curling, distorted leaves, and sticky sap buildup.
They are easy to remove with water sprays, insecticidal soap, or neem oil.
Fungus Gnats
Fungus gnats are usually a sign the soil is staying too wet. The adults are annoying, but the larvae can damage roots over time.
Let the soil dry more between waterings and use yellow sticky traps to control adults. Better drainage helps prevent them from coming back.
