Philodendron black cardinal does not grow black color leaves. It grows burgundy leaves that become too dark and they look like black color. In the initial growing stage, the plant only produces pure burgundy leaves. As it gets mature the leaf color becomes darker, close to the black color.

If you like to have a dark foliage plant in your indoor plant collection. Then you should check this article to know more about the growth and care tips of black cardinal philodendron.

Philodendron black is a medium-height plant. Generally, it grows near about 2.5 to 3 feet tall and spread half feet. The big size leaves look very beautiful and make it a unique plant in the philodendron family. 

Your methods of care and maintenance will decide the health and leaf size of this plant. Therefore, you should read this care guide before growing it.

3 feet heigh of an indoor plant is normal. Such plants are easy to maintain and they look good in big size rooms. Another good thing is you don’t need to worry about where to put it. Because it is a floor plant you can place it anywhere you want in your house.

The best thing that I like about this plant is it does not require frequent maintenance (pruning & trimming).

You only need to clean the old and dead leaves of the plant in the spring season (sometimes in winters).

Light Needs

Like another philodendron, it needs indirect bright light. Your plant will grow healthy and produce lots of beautiful leaves.

But if you want your plant to produce shining burgundy foliage. Then you have to expose it to the morning and evening Sunshine.

Because the warm sun rays increase the production of chlorophyll. Higher the amount of chlorophyll means the deep color of leaves.

Remember that it cannot survive in mid-day light. The high-intensity light can damage the plant leaves. It will lose its natural dark color and turn yellow.

Brown tips are also a sign of over-exposure to the sun or too bright light.

Indoors, place it a few feet away from the sunny window. If you see your plant is stretching towards the source of light. Then move it close to the light source and it will grow dense.

Potting Soil

This is the important part of its care. Because mostly we use general-purpose potting mix for growing houseplants. But in the case of Black cardinal philodendron things are a little different.

General soil absorbs lots of water which is not good at all for this plant growth.

Also, the regular potting mix becomes heavy when watered. This put negative pressure on plant roots. Philodendron black cardinal roots become weak when they work under some stress.

This results in weak plants with medium size leaves. To avoid such issues, use African violet potting soil. This type of soil is well-draining and lightweight. It does not become compact after watering plants.

Moreover, potting mix for violets reduces the chances of root fungus and leaf fungal diseases.

Watering

The deep watering technique is the best option to avoid all watering-related issues. For watering black philodendron place the pot in the water tub and let the roots absorb desired amount of water.

Then after about 10 minutes lift the pot and place it in a dry place. Let it drain water through the bottom hole and it will take 30 minutes to do so.

Then empty the saucer and place your plant in its location. This is an easy and safe watering technique for particularly this plant.

For the next watering session, let the soil of the pot dry. When you touch the soil and you feel the top few inches are dry. It means this is the right time to water your black cardinal philodendron.

Fertilizing

In order to help your plant to produce large size shining leaves. You should give it a nutrient boost in the form of liquid fertilizer.

Any high-quality general-purpose foliage fertilizer will do best. Use it only once per month.

Before using the supplement, you should read the instructions written on the bottle carefully. Because every manufacturer makes different potency fertilizers.

So, they have little different dilution instructions. 

Spring and summer are the only fertilizing time. Skip it in the winter season.

Temperature & Humidity

You do not have to worry about the room temperature and humidity. All the USDA hardiness zone are good to grow it indoors.

The general room humidity and temperature are best for it. No need to make changes to them.

Just make sure your black cardinal cannot come in contact with cold winds. Because it is a frost-sensitive plant it cannot survive in cold weather.

You can bring it outside but only in spring and summer. Once the winter hits bring it back indoors and place it in some warm place.

Do not let the cool conditioner air and hot air flow towards the plant. Both the conditions are deadly for it.

Repotting

Once you see that your plant is not growing tall and it look uncomfortable in its current pot. It is time to repot it in a new home.

Following are the best repotting steps:

Buy a plant pot 2 inches deep and wider than the current pot

Fill it with new potting soil to its half.

Gently take out the plant from it old pot

Inspect the roots, if you find damages cut the damaged part

Place it in the new pot and fill the remaining empty portion of the pot

Tap around the plant to help it stand firmly.

Give some water to the base of the plant and follow regular care.

Propagation

The black cardinal philodendron is very beautiful. You will definitely think about propagation to have some more black cardinals.

You have two options one is stem cutting and growing it in water. In this method, you need to change the water when it gets dirty and unclear.

But I recommend the root division method and it is better than the stem cutting technique.

Just unpot the plant divides its roots into different sections. Then plant each divided section in a separate pot. This way you will have multiple black cardinals propagated plants.

Conclusion

Its beautiful deep burgundy leaves make it a unique houseplant. The large size leaves are easy to maintain and care for.

Just choose the right potting soil and water it only when it requires. Your plant will never face any problem. For more information contact us anytime.
