Philodendron Subhastatum Care And Tips – Ultimate Guide

Philodendron Subhastatum Care: Today’s article will be about the Philodendron subhastatum. It is a rare tropical climber, and it is from the Araceae plant family.

The philodendron genus can be considered one of the largest in the Araceae plant family. There are more than 400 species in the genus, all of which come in different sizes and colours.

You must give your Philodendron Subhastatum plenty of water and less sun to ensure it grows well. The plants have enjoyed a high level of humidity since their origin in West Indies’ tropical forests, near the riverbank.

Because of its bi-foliage leaves, the Philodendron Subhastatum has been a favourite ornamental plant. The leaves’ front side is green, but the reverse side of the leaf is reddish. As the plant ages, it becomes redder.

Philodendron Subhastatum is a climber and can be used as wall decorations or pole decorations. Your Philodendron doesn’t need to be kept in a pot.

The Philodendron adds to the space’s atmosphere, but it is also great for purifying the air. This plant can absorb many chemicals such as formaldehyde and ammonia. It can also be used as an indoor air purifier.

Soil Mixture

For Philodendron Subhastatum, I prefer well-drained and rich organic soil.

The soil should have the same proportions of loam and sand as peat. As a soil amendment, I recommend compost. The soil should have an alkaline pH between 7-8. Alkaline soil contains more macronutrients that are essential for Philodendron’s healthy growth.

By ensuring that soil is well-drained, you can ensure that it has enough water.

Philodendron Subhastatum Watering

The Philodendron Subhastatum loves water. This means that you can water the plant as often as you wish.

One important thing to remember is the level of overall moisture in the Philodendron subhastatum. You must ensure that the soil’s top layer is at least 2 inches dry.

To check the soil texture, I recommend using your finger. You can also use a moisture meter to check the soil’s texture. Overwatering is a major mistake that can instantly kill the Philodendron Subhastatum.

Philodendron Subhastatum Light Requirements

My Philodendron Subhastatum is kept out of direct sunlight. This plant is very sensitive and can easily burn if placed in direct sunlight.

Natural and filtered are the preferred light types for Philodendron Subhastatum. Natural sunlight might not always be available in certain parts of the world. You can grow your Philodendron Subhastatum in artificial lighting conditions.

If direct sunlight is your only source of light, you should make sure there is a filter such as a sheer curtain to mellow the light.

If you want your plants to grow evenly, light must come from all directions. You can rotate the plant if the light source is only coming in one direction.


Your Philodendron Subhastatum should be grown at temperatures between 50 and 86 or F (10 to 30 degrees Celsius). This is a good sign because it shows that this species can thrive in indoor conditions.

Below temperatures of 59 orF (15° Celsius) is where Philodendron Subhastatum will not thrive. It is strongly recommended that your Philodendron Subhastatum be brought inside during winter.

Philodendron Subhastatum Humidity

Because they have thin leaves, the pores of Philodendron Subhastatum can dry out quite quickly, especially in summer. This is why I recommend that the Philodendron be kept in a room with 60 to 80% humidity.

It can be tiresome to water the plant every day, especially in summer. Instead, I spray the leaves with mist after about an hour or two. To provide the best humidity for your Philodendron Subhastatum, you can also use a humidifier.

The moisture content can be increased by placing more water-loving plants within the same area of your Philodendron.

You can easily maintain the moisture content of your Philodendron Subhastatum by placing it in a pebble tray.

  • Pour some water into a tray.
  • Place the pot on the pebbles in the second step.

A pebble-tray can be used as a home remedy to retain moisture and prevent water from evaporating.

Philodendron Subhastatum Fertilizer

Every week during the growing season, I fertilize my Philodendron Subhastatum. Your plant will not be affected if you skip one week. Overfeeding your Philodendron Subhastatum can cause damage to the roots.

Over-fertilizing can lead to an increase in salt levels and a disruption of the soil’s pH. Good micro-organisms in the soil also begin to die. This causes stress to the roots of Philodendron Subhastatum as it must work harder to absorb nutrients at higher salinity.

I don’t usually eat as much in winters because PhilodendronSubhastatum is going through a resting period at the moment. Philodendron Subhastatum uses Dormancy to thrive in cold environments. Although your Philodendron might not be as vibrant as it was before, it is still very active.


Philodendron Subhastatum has strong root systems. The plant’s overall growth slows down if its roots don’t have enough room to grow. However, Philodendron Subhastatum is slow to grow so I repot the plant every 2-3 years.

If your Philodendron Subhastatum is growing very quickly, it will need to be repotted, preferably during the spring and summer seasons. These are the growing seasons. Therefore, it is important to repot your plant during these seasons.

  • First, I remove the Philodendron Subhastatum and clean the roots.
  • Next, I carefully place it in a larger pot.
  • Then, I water the plant and fertilize it as usual.

Repotting prevents your plant from becoming sick. This will encourage growth and give your plant a healthier appearance.

Philodendron Subhastatum Pruning

Philodendron Subhastatum does not require pruning. If you do feel the need to prune, make sure that your equipment is clean and well-sanitized. This will help prevent infection and germ transmission.

You should also be careful not to cut too much off the plant. Otherwise, the growth of the Philodendron Subhastatum will be affected.

Make sure the plant is clean and free of dust. This will improve the appearance of your plant and help you keep it tidy.

Philodendron Subhastatum Propagation

The spring season is the best time to propagate Philodendron Subhastatum. This is right after their come out of dormancy. Propagation can be done by tip or stem cutting. The parts of the propagate grow well in both soil and water.

Begin by placing the desired cut in the medium under the best conditions.

Water Propagating

  • Fill a jar with water. Allow the water to sit overnight so that the chlorine can dissipate before you start propagating.
  • Place the cut in the jar. Place the stem so that at least two or three nodes are submerged and two to three leaves remain.
  • I recommend changing the water every 2 to 3 days. To prevent algae growth, make sure your Philodendron Subhastatum-propagated stem is not exposed to direct sunlight.
  • Once roots are visible and begin to grow, you can transfer the plant into a pot. You will continue to water it as it grows.


  • Fill a container with the potting mixture. Then, place the cutting in the pot.
  • Cover the pot with a clear plastic wrap to retain moisture. To prevent microbial growth, remove the bag every once in a while.
  • Baby Philodendron Subhastatum plants need to be watered frequently and kept at a warm temperature.
  • To ensure that the plant is growing roots, I gently pull the Philodendron Subhastatum pot to check for resistance.
  • Once the plant is at a healthy growth stage, I move it to a larger pot.


Philodendron Subhastatum belongs to the Philodendron family. They never have flowers. Their bi-foliage leaves are two-coloured, a dual colour combination of green and red.

Philodendron Subhastatum Growth Rate

The environment they are placed in and the care they receive will have a significant impact on their growth.

They grow slowly and require patience. This plant can grow up to 6 feet long and 24 inches wide.

Philodendron Subhastatum is a long-lived, green plant that can grow to 2 feet in height and 4-6 inches wide.

Common Problems for Philodendron Subhastatum

See the source image

The Philodendron Subhastatum can be used as a topical herb. If it is not taken care of, common diseases and pests could cause damage.


These pests are known to be plant-sucking and can thrive in warm environments. Mealybugs can infest Philodendron Subhastatum if they are kept in extremely hot temperatures.

The mealybugs look like a rough cotton mass on the Philodendron Subhastatum’s leaves, stems and nodes. The insects eat the sap and take away the nutrients from the plant, making it weak. These bugs are not harmful, but if they are not controlled, they can cause yellowing or curling of the leaves.

Honeydew is a sticky liquid that bugs leave behind after they have been fed. This encourages mold growth.

Regularly wash leaves of Philodendron Subhastatum with leaf shine to prevent them from growing. These pests can be removed from plants that have already been treated.

Neem oil is an organic alternative to conventional medicine. It inhibits the growth and reproduction of insects such as mealybugs.

Algal Leaf Spot

This is a common foliar disease that affects Philodendron Subhastatum plant species in humid environments. Cephaleurosvirscens is the organism that causes this disease. It is a parasitic algae that eats plants with leathery leaves like Philodendron Subhastatum.

The Algal leaf spot appears as a grayish-green spot on the Philodendron Subhastatum leaf surface. These spots can grow to a maximum of 1/2 inch in size. The leaf tissues eventually die and the leaves drop prematurely.

Use good cultivation techniques to ensure healthy plant growth. This disease is only for weak Philodendron Subhastatum. To improve air circulation and reduce damage, prune excess vegetation. Copper-containing chemical fungicides can be used if necessary.

Cold Injury

Philodendron Subhastatum, a tropical tree, is vulnerable to low injury. Temperatures below 59 orF (15°C) can cause stunting, wet-looking leaves, lesion formation, and even death.

Your Philodendron Subhastatum will suffer more damage if it is exposed to cold temperatures. These plants are less resilient to cold because they do not have the same amount of unsaturated and saturated fatty acids in their membranes.

Keep your Philodendron Subhastatum out of direct sunlight to prevent injury from cold. In winter, keep them indoors in warm temperatures.

Magnesium Deficiency

Philodendron Subhastatum requires good soil for growth. It must be fertilized regularly. The soil can become deficient in certain nutrients, which can lead to the plant suffering. Magnesium is one such important mineral nutrient.

Magnesium is essential for the healthy growth of Philodendron Subhastatum. The soil is often not fertile enough to have enough magnesium. The mineral can be leached from the soil by overwatering. The fertilizer and potting mix that has a higher potassium-to-magnesium ratio will be more easily absorbed.

Philodendron Subhastatum develops yellow leaves due to a deficiency in the mineral. If the mineral is not taken care of, the plant will eventually die.

Rich organic compost is essential to prevent magnesium deficiency. Good compost retains moisture and prevents nutrients from leaching.

Sometimes I use chemical leaf sprays as a temporary solution. Use Epsom Salts to increase nutrient uptake in the roots of your Philodendron subhastatum.
