Origin and History

Philodendron Dark Lord belongs to the Philodendron genus in the Araceae family that contains more than 3000 known plants. It is native to the tropical rainforests of Colombia and Panama and is a hybrid variety of the Red Philodendron erubescens and Philodendron hederaceum.

The Philodendron genus is further divided into two groups- the lacy leaf Philodendrons and the non-lacy leaf Philodendrons.

The Dark Lord belongs to the non-lacy leaf variety. Philodendrons are aroids, which means that they produce flowers that grow on an inflorescence.

The Philodendron Dark Lord is no different and has small white flowers that give way to orange berries.

However, these flowers and fruits are rarely seen in indoor plants, requiring specific conditions to bloom. These conditions are almost impossible to replicate in a home environment.

Philodendrons were first introduced to Europe in the 17th century and became trendy houseplants by the Victorian era.

They were brought to America by settlers in the 1800s and have been widely cultivated. Philodendrons are one of the most popular houseplants in the world, and Dark Lord is one of the most popular!

It gained popularity among gardeners over the past 15 years thanks to social media; before that, it was almost unknown. Since then, its demand has been increasing daily among plant lovers, but the supply is not at the same pace, making it a bit expensive and rare plant. It’s truly a must-have plant for any Philodendron collector.

Follow this guide until the end to learn how to care for Philodendron Dark Lord.

Philodendron Dark Lord Care Overview


The philodendron Dark Lord is a tropical plant that requires bright, indirect sunlight to thrive. It is best to place it near a window where it can receive plenty of light without being directly in the path of the sun’s rays. 70-80% of bright indirect sunlight is ideal for it.

A south-facing window is usually the best option for your plant. 2-3 hours of direct morning sunlight won’t do any harm. Generally, 8-10 hours of daily indirect light is best for it to grow healthy and large.

If your window receives too much sunlight, you can hang a curtain to diffuse the light, or you can place your plant a little further from the window.

If you don’t have a spot near a window that gets enough light, you can supplement the sunlight by using a grow light.

Grow lights are artificial lights that simulate sunlight and are very helpful for indoor plants, especially during winter.

Should you feel you have a spot in your home that will provide Philodendron Dark Lord with the perfect amount of light, but you’re not sure, you can always use a light meter to measure the intensity of the light.

A range of 500-700 lux is ideal for Philodendron plants. Anything more than that will lead to the leaves getting burned, and anything less than that will stunt the growth of your plant.


A well-draining, nutrient-rich, dry potting mix with a pH of 5.5-7.5 is ideal for the . A soil mix that is too dense will not drain the water efficiently and cause a deficiency of oxygen, ultimately leading to root rot.

You can use a commercially available potting mix or make your potting mix by combining two parts peat moss, two parts perlite, 1 part all-purpose soil, and 1 part vermiculite.

The peat moss will help drainage and aeration, while the perlite will provide structure and support. The all-purpose soil will add nutrients, and the vermiculite will hold moisture.

It’s essential to have good soil to provide Philodendron Dark Lord with the nutrients it needs to grow. Starting with the right soil mixture will ensure that your plant is healthy and has a strong foundation.

Generic potting soil can be too dense for the Dark Lord and cause drainage problems. This can lead to root rot or even death, so it’s essential to be mindful of the type of soil you use.

If you’re unsure whether your potting mix is too dense, you can always test it by taking a handful of the mixture Squeeze it and if water drips out, then it is too dense. If no water comes out, then it is perfect for Philodendrons.

Philodendrons will also benefit from being planted in a pot with a drainage hole to allow excess water to escape. An 8-10 inches deep pot is ideal for small- to medium-sized plants.


Philodendron Dark Lord should be watered when the top 1-2 inches of soil is dry to touch. The watering frequency will vary depending on the amount of light your plant receives, the size and type of pot it is planted in, and the kind of potting mix.

If it is planted in smaller pots, it would need to be watered more frequently than those grown in larger pots.

Philodendrons planted in well-draining potting mixes with lots of organic matter will need to be watered less often than those planted in poorly draining potting mixes.

It is very efficient in storing water, so it’s better to underwater than overwater your plant. Overwatering will result in yellowing and wilting of leaves, stunted growth, and in extreme cases, root rot.

How to Water your Dark Lord Plant

The best way to water Dark Lord philodendron is to use the bottom-up method. This means you will place your plant in a water container and allow it to soak for 15-30 minutes.

After that, drain the pot and remove excess water from the saucer. Allowing the plant to sit in water will cause the roots to rot, so it is essential to remove any excess water.

Helpful tip: If you use tap water, it is best to let it sit out for 24 hours before watering your Philodendron. This will allow the chlorine and other chemicals to dissipate, making it safer for your plant.

Philodendrons are also very sensitive to fluoride, so it is best to use filtered or distilled water if you have fluoride in your water.

It’s necessary to fertilize your plant more frequently because distilled water does not contain any nutrients.


Philodendron Dark Lord is not a heavy feeder, but it will benefit from being fertilized once a month during the spring and summer months when it is actively growing. Use a balanced, water-soluble fertilizer with an NPK ratio of 10-10-10 or 20-20-20.

NPK stands for nitrogen, phosphorus, and potassium. These are the three primary nutrients that plants need to grow. Nitrogen is responsible for leaf growth, phosphorus is responsible for root growth, and potassium is responsible for overall plant health.

Be sure to dilute the fertilizer to half the recommended strength before applying it to your plant. They should not be fertilized when they are dormant during the fall and winter months.

It’s better to under-fertilize them than to over-fertilize them. Over-fertilizing will result in browning and wilting of leaves, stunted growth, and in extreme cases, root burn. Fertilize the plant almost 6 inches from the stem, so you don’t burn the roots.

You can use an organic fertilizer made from compost or manure. If you choose to use organic fertilizer, it is best to apply it once a month during the growing season.

Apply the fertilizer at the base of the plant, taking care not to get any on the leaves. I like to use worm casting or compost tea as an organic fertilizer. Works impressively for their growth!

How to Fertilize Your Plant

Look at your Philodendron Dark Lord and determine if it needs to be fertilized. An excellent way to tell is by looking at the leaves. If the leaves are bright green and look healthy, they probably don’t need to be fertilized. The leaves might need a little boost if they are yellow or pale green.

Take about 1/2 teaspoon of fertilizer and mix it with a gallon of water. Use this mixture to water your plant. Apply the fertilizer around the base of the plant, taking care not to get any on the leaves.


The philodendron Dark Lord is a tropical plant that prefers warm, humid conditions and prefers an indoor temperature of 70-85 degrees Fahrenheit (21-29 degrees Celsius). If your plant is exposed to temperatures below 55 degrees Fahrenheit (12.5 degrees Celsius), it may suffer from frost damage.

Anything above 60F would work for it. Try to give it a constant temperature and avoid any sudden temperature changes. Philodendron Dark Lords are very sensitive to drafts, so make sure they are not exposed to any cold air from windows, doors, or vents.

If you are moving it to another place, consider the temperature change. If you’ve placed your plant outside, move it inside during the winter. Do not let your plant get exposed to frost, it will likely lose all its leaves and die.


The Dark Lord plant prefers humid conditions with relative humidity above 70%. However, it thrives well at a room’s average humidity level (40-50%) too. With high humid conditions, this plant grows faster and more healthy.

If the air in your home is too dry, you can increase the humidity around your plant by placing it on a pebble tray or using a humidifier. A pebble tray is simply a shallow tray filled with gravel and water. The evaporation of water from the stone will increase the humidity around it.

Be sure to change the water in the pebble tray often to prevent it from becoming stagnant. You can also group it with other tropical plants to create a mini jungle that will increase the humidity around all of the plants.

If you live in a very arid area, you may have to mist your Philodendron daily or multiple times to keep the leaves from drying out and turning brown.

Brown, dry leaves indicate that the air is too dry for your plant. A humidifier will help increase the air’s humidity and prevent the leaves from drying out. Using this during the winter months will be especially helpful in preventing the leaves from drying out.


Philodendron Dark LordPhilodendron Dark Lord does not require much pruning, but it will benefit from being trimmed back when it gets too big or starts to look leggy.

It can be trimmed back by up to one-third of its total length. When trimming your plant, use sharp, clean shears or knives. Cut off yellow, brown, or dead leaves and leggy stems.


The philodendron Dark Lord plant does not bother you to repot them too often. They can stay in the same pot for 2- years. Check if the plant is becoming root bound, then it’s time to move them to a bigger pot as being root bound for too long can stunt its growth.

Spring is the best time to repot it and don’t repot during winter. When repotting your plant, use a well-draining potting mix and a pot that is only one size larger than the current pot and has a drainage hole.

Signs your plant needs repotting:

  • The plant has outgrown its pot
  • There is extensive root growth coming out of the drainage holes
  • The plant is top-heavy and unstable
  • The roots are tightly bound and circling the inside of the pot

Plants don’t often like replanting, so it can take a few weeks to adjust to their new pot. Be sure to give it extra TLC and watch for any signs of stress, such as yellowing leaves or stunted growth.


Stem cutting is the easiest and most successful way to propagate your Philodendron Dark Lord and grow your tropical plants’ collection. Follow the below simple steps to propagate your plant by stem cutting:

  • Fill a small pot with a well-draining potting mix.
  • Choose a top stem at least 6 inches long with several leaves.
  • Cut the stem at an angle below a leaf node using sharp, clean shears or knives.
  • Dip the cut end of the stem in rooting hormone.
  • Place the stem cutting in the pot and lightly cover it with the potting mix.
  • Water the soil until it is evenly moistened, and place the pot in a warm, humid location.
  • Keep the soil moistened but not soggy, and Within 3-6 weeks, you should see new growth emerging from the soil.
  • Once new growth appears, you can begin watering your Philodendron Dark Lord as usual.

It can also be propagated using division. Mature plants can be divided into several smaller plants. Philodendrons can be difficult to divide, so it is best to leave this to an experienced gardener.

If you choose to try it, you must carefully dig up the plant and gently pull it apart into two or smaller plants. Be sure to use a sharp knife or shears to make clean cuts through the roots.

Each division should have several leaves and at least one good root system. Replant the divisions in well-draining potting mix, and water them well.


The Philodendron Dark Lord is a fast-growing plant and can grow up to 24 inches per year. They can reach a height of 12-15 feet and a width of 12 feet in ideal growing conditions. In a home environment, they are typically much smaller, reaching a height of only a few feet.

The Dark Lord is not picky about its growing conditions and will do well in most indoor environments. It prefers bright, indirect light but can also tolerate low-light conditions.

It is an easy plant to care for and makes an excellent choice for beginner gardeners.
