The Philodendron McDowell plants prefer warm, moist environments. It needs bright, indirect sun and moderate watering approximately once per week. Keep the temperature between 55 and 80 degrees Fahrenheit (or 26.6 to 26.6 Celsius).

A soil mixture containing peat, orchid bark, and perlite is recommended. The ideal humidity level is between 65-75%. Use a balanced fertilizer to fertilize your houseplants every four to six weeks during the spring and summer growing seasons.

Soil Mixture

The Philodendron McDowell plant, like many other species, thrives on moist, well-draining soils.

I keep my ground mixture high in organic matter and often add materials such as peat, perlite, and orchid bark.

Each one keeps the soil hydrated and prevents water accumulation.

Many gardeners recommend coconut coir, or compost to prepare the Philodendron McDowell plants’ soil mixture; this mixture works well.

Make sure that you have at least two drainage holes in the bottom of any soil mixture that you create.

This is the key point. Keep the Philodendron McDowell plants hydrated, but not in wet soil. The chances of getting fungal and bacterial infections are high if the plant is left in water for a long time.

Philodendron McDowell Watering

When watered twice a day, the Philodendron McDowell plants thrive. To avoid shock, I recommend adding room temperature water that is free from chlorine and fluoride.

The plant can have different wagering requirements depending on its environment. The Philodendron McDowell plants usually require more water during summer. It needs less water in the winter.

When the Philodendron McDowell plants topsoil layer (2-3 inches) appears to be drying out, water it.

Water should be added from the top, not directly to the soil. Make sure to cover all areas and then wipe off any excess moisture.

If the Philodendron McDowell plant’s large leaves seem dry and dull, it could be mildly or severely dehydrated.

However, it is possible to overwater your plant if the soil is too wet or if the plant has a tendency to catch infections. You should maintain a moderate watering schedule, changing according to the season.

Light Requirements

Light is one of the most important factors in plant growth. The amount of light that is provided to a plant is a major factor in its colour and shape.

For the Philodendron McDowell, you should provide bright, indirect light (indirect lighting).

The Philodendron McDowell hybrid plant can handle many light settings.

For the best growth, however, it is important to have dappled sun. If you have a Philodendron McDowell indoor plant, position it near an east-, west-, or south-facing window.

Shaded balconies or patios are also options for growing the Philodendron McDowell plants. If you are planting the plant outdoors, make sure it is under a tree canopy.

McDowell can carry out its essential functions with filtered sunlight without burning its leaves and dehydrating them.


The Philodendron McDowell plant thrives in temperatures between 55 and 80 degrees Fahrenheit (12.7 up to 26.6 degrees Celsius).

Although it is slow to respond to adverse temperatures, the plant slowly starts showing signs such as yellow leaves and stunted growth.

It may take some time to determine why your body is reacting to the incorrect temperature.

Anything less than or equal to this could result in unpredictable growth or even no growth.

This temperature range is easy to maintain indoors, but it can be difficult to maintain outdoors.

This beauty can be brought inside if the temperature is above 85 degrees Fahrenheit and below 50 degrees Fahrenheit.

Philodendron McDowell Humidity

Humidity is another important factor in the growth of the Philodendron McDowell plants. Ideal humidity levels should be between 65% and 75%.

The plant can stay hydrated with moderate humidity without being exposed to pathogenic organisms.

To maintain the humidity level, you can install a humidifier inside your home. You can also keep an eye on it with a hydrometer.

If you prefer to keep it simple, you can mist the plant every other day, or put it together with your other houseplants.

Philodendron McDowell Fertilizer

The Philodendron McDowell plants thoroughly enjoy fertilizers that have a balanced NPK, which contains many macro-and micronutrients like calcium and manganese.

Your Philodendron McDowell plants should be fed with a high-quality fertilizer once every four to six weeks during the spring and summer growing seasons.

Winters are a good time to reduce the frequency of feeding.

Growers can choose between slow-release powder fertilizers and instant-action liquid feeds. The latter is best for the Philodendron McDowell plants.


Repotting the Philodendron McDowell plants is not recommended until they reach full maturity. After it is fully mature, you can refresh the soil and move it to a larger pot.

Make sure the pot has good drainage and aeration.

For the first repotting, a container measuring 6-8 inches (13.5-22.5 cm) is ideal. As the plant grows, a container of 15 to 20 inches (38 – 50.8 cm) is ideal.

If your plant is large, it is usually not necessary to increase the size.

After the soil has been repoted, you can replace it with fresher, more nutritious constituents. To help maintain good moisture levels, add peat moss and orchid bark.

Philodendron McDowell Pruning

In its first year, your Philodendron McDowell will not need to be pruned. It will require some trimming as the plant grows, and more care for its neat appearance.

Pruning is a great time to change the appearance of your plants. It also allows you to check for signs of disease or infection.

Begin by cutting the most irregular-looking vines. If the branches are discoloured or diseased, do not remove them.

To encourage new growth, you can also pinch the ends. When cutting, be sure to look closely at each leaf and vine.

After you have finished pruning, spray some fungicidal oil over your Philodendron McDowell plants to ensure that no open cuts are left.

Also, make sure to use sterilized pruning hears.

Although propagation can seem complicated, don’t worry. You won’t have to worry about the Philodendron McDowell plants.

It can be propagated by rhizomes and stem cuttings. You can propagate it in spring for best results.

  • Begin by removing a healthy-looking stem with at least three nodes.
  • Put the stem in the rooting powder, and then sprinkle the powdered fungicide powder on top.
  • This stem cutting should be placed in a suitable soil mixture, preferably containing peat moss or snailnum.
  • This stem cutting should be placed in indirect sunlight and kept warm.
  • You can propagate your plants in water by placing the stem cutting into water.
  • Once you notice new shoots or roots, place the stem in a small container and let it grow in indirect sunlight until it matures.


The Philodendron McDowell flower is rarely seen and can only be found in conservatories. They have a simple appearance with a spadix (white part) and green leaves-like coverings.

Flowering can take up to 16 years, and it is quite a lengthy process. It blooms between May and July once it is mature.

Philodendron McDowell Growth Rate

Philodendron McDowell, a fast-growing species, can grow to approximately 78 inches (198cm) in the right conditions.

Indoor varieties may not grow as tall as indoors because they are cultivated with in-house conditions in mind.

9b-10 are the best areas for Philodendron McDowell plants. The best zones for growing the Philodendron McDowell plant are 9b through 10.

Common Problems for Philodendron McDowell Plant

Yellow Leaves

yellow leaf is a common problem with the Philodendron McDowell plants.

There are many reasons they can form, but the most common include insufficient sunlight and poor watering.

At first, only small areas of the leaves will lose their colour. You will notice the yellowing of entire leaves as the condition worsens.

It is difficult to save the leaves that are discoloured, but it is possible to prevent further damage.

Begin by assessing the location of your plant. Make sure that your Philodendron McDowell plants are in direct sunlight.

Next, review the plant’s watering schedule and only water it when the soil is slightly dry. Don’t overwater the plant or submerge it as this can cause yellowing and other problems.

Insects and Pests

Pest infestation is another nerve-wracking problem that the Philodendron McDowell plants face.

They will often have established themselves well before you notice them.

Infestations can start in the nursery or at your home. This means that your other plants may also be infected.

Mealybugs and spider mites are the main culprits. They roam the leaves looking for cell sap and shelter and cause havoc.

Spider Mites & Mealybugs

Spider mites can be a little harder to identify, but they leave behind cottony webs which make their diagnosis much easier.

Use an insecticide spray or neem oils to treat infested plants. Spray it on the entire plant to get rid of it.

Root Rot

Another common problem with the Philodendron McDowell is rootrot. This is a slow process that can take a lot of time.

This happens most often when the roots of the plant are submerged in water or if there is insufficient drainage.

Because the roots are unable to absorb vital elements from the soil, the plant’s nutrient supply has been significantly reduced.

The plant loses its colour and then starts to wilt. If not treated promptly, the plant could even die.

You can reverse the damage by taking the Philodendron McDowell pot out of the pot and inspecting the roots, as well as the pot.

A yellow-tinged root indicates that the plant is fine. However, mushy roots can cause the plant to die quickly.

To get rid of excess water, place the plant in direct sunlight. To prevent infection, dry the soil and apply a fungicidal treatment.

Tips to Grow Philodendron McDowell

  • You should not water your plant until the topsoil layer is slightly dry.
  • You can place it in bright, well-filtered sunlight, indoors if possible.
  • The plant is sensitive to extreme temperatures so it should be protected.
  • To feed your plants during the spring and summer, use balanced NPK fertilizers of high quality.
