What Is It?

What is It
Philodendron Brandtianum also goes by the names Silver Leaf Philodendron and Philodendron Brandi.

There is a famous saying that in warm climates, Philodendrons are the easiest plants to grow and the hardest to kill. This makes them sought-after plants for any household. Some of the more popular varieties include the Philodendron Pink Princess, The Philodendron Birkin, and the Philodendron Rio.

There are over 400 species to choose from in a variety of shapes, colors, forms and sizes – a plant for every corner of the room. What makes Philodendron brandtianum special is its silver and green foliage, hence the common name Silver Leaf Philodendron. It is also known as Brandi Philodendron.

History

Silver Leaf Philodendron Plant Up Close
Philodendrons have been around for quite some time, but this one in particular was named in 1913.

Philodendrons are the second largest genus under the family Araceae. Many of these are houseplants. The name Philodendron comes from the Greek philo for love or affection and dendron for tree.

Philodendrons were collected in the wild from as early as 1644 by German naturist and astronomer Georg Marcgrave. More significant was the contribution to the collection of the species by French botanist Charles Plumier. His name may be familiar, as the Frangipani genus Plumeria is named after him.

Appointed as the royal botanist to King Louis XIV of France in 1693, he became one of the most important botanists of the time. His explorations from 1689 to 1704 gave us plants like Fuchsias and he collected a few Philodendron species from the islands of Martinique, Hispaniola, and St. Thomas in the West Indies.

More species were collected by Dutch botanist Nikolaus Joseph von Jacquin between 1755 and 1759 in the West Indies and Central America. These species were first added to the genus Arum and only later in 1829 were they classified as Philodendrons.

When it comes specifically to Philodendron brandtianum credit goes to Kurt Krause (1883 – 1963), a German botanist who named the plant in 1913. His claim to fame was writing five books on the flora of Turkey, but he still had time to find many other plants from around the world.

Native Area

Philodendrons are found in the tropical Americas and the West Indies and come from a variety of habitats.

Philodendron brandtianum comes from the northern regions of South America – Southern Colombia, Northern Brazil, and Bolivia. They are found in tropical forests where they climb and make their home under the canopy of trees.

Botanical Characteristics

Before we get into how to care for this popular houseplant, let’s take a look at the botanical characteristics. It’s important to understand this plant’s native environment, as it will typically perform the best when that habitat is mirrored to the best of your ability.

Growth Habit

The Philodendron brandtianum can grow in multiple forms including as an epiphyte, a hemiepiphyte, or terrestrial plant.

In their natural environment, some Philodendrons choose to grow as epiphytes to make use of the light, misty areas of the upper story of the rainforest.

On the ground, the competition for nutrients, water, and air is tough, but higher up there are pockets of nutrients to be found in the branches of trees that climbing plants like Philodendron brandtianum can take advantage of, as well as the extra light and moisture.

Grown as an epiphyte, Philodendron brandtianum needs some sort of support like a tree or trellis to grow up, and clean air and water around it to gather nutrients.

Epiphytic Philodendrons sow their seed in the upper story of the forest. These little seedlings grow as epiphytes and then once they reach a certain size, they send aerial roots downwards that eventually touch the ground where they can then take up nutrients, air and water from the forest floor. These are the hemiepiphyte Philodendrons.

Terrestrial philodendrons grown in soil are the most common ones we use as houseplants. It is easier to get nutrients and water to a plants’ cells by adding these to the soil.

Each of these ways to grow the plants will have an effect on growth. Some will cause the plant to grow slower and can even produce different markings on the leaves. Sunlight, temperature, and soil type also have an effect on the final color and form of the plant.

Appearance
Characteristics of Silver Leaf Philodendron Houseplant Leaf Up Close
These plants have broad heart-shaped leaves that are mottled with dark olive green and silver. 

As they grow, Philodendrons develop patterns at a cellular level that allow the leaves to change their appearance. This ability can change the leaves of Philodendron brandtianum from shades of orange to the blends of olive green and silver.

The leaves are also different sizes depending on environmental and growing conditions. The average leaf is 4-7 inches and when mature, the plants can grow up to 12 inches long.

This plant grows to around 4-5 feet indoors. Outdoors and in ideal conditions, they can get much bigger.

Planting

Planting
Warm, humid climates are best, but Philodendron brandtianum is most commonly planted indoors.

Philodendron brandtianum is a plant with multiple uses in a design. Plant in a hanging basket or a pot to tumble over the sides, or train it up a support like a moss pole. It can also be added to a terrarium for a contrasting color with other green-leaved plants.

These plants can also be grown outdoors under trees in dappled shade. They do well in USDA Zones 9-11 outdoors. Outside these zones, it’s best to grow indoors where heat and humidity can be controlled.

How to Grow

When it comes to growing Philodendron brandtianum, there are many different factors to consider. This plant needs the proper amount of light, water, fertilizer, and the right soil for it to reach its maximum growth potential. Let’s look at each of these important factors in greater detail.

Light

Upward Vining
It is best to place your Philodendron brandtianum where it can receive ample bright indirect light.

As with most houseplants, Philodendron brandtianum needs bright indirect sunlight. It will grow in lower lighting conditions, but won’t perform as well. Intense direct sunlight will burn and damage the leaves, inviting bacteria and pests to attack.

If the leaves start to yellow, it may be a sign that the plant needs more light. Try a south or west-facing window with filtered sunlight.

To grow outdoors, the plants must be sheltered from direct sunlight for most of the day. Dappled shade under trees is ideal.

Water

Proper Watering
Always perform a finger check to see if the top layer of soil is dry before watering.

In its natural environment, Philodendron brandtianum receives a well-balanced supply of moisture. A constant steady water supply is essential for these plants to thrive. However, it’s vital to wait for the top 2-3 inches of soil to dry out before watering again to prevent waterlogging.

In the heat of summer, the plants need watering about 2-3 times a week. In winter, however, watering can be reduced to about once a week on average. Keep an eye on what works best in your own indoor environment and adjust as necessary.

Water deeply and make sure the water fully drains out the bottom of the container before placing in its normal spot. As with all epiphytes, it’s sensitive to overwatering and needs excellent drainage.

Contrary to its wish for lots of water, this plant can handle a missed watering quite well due to its tough nature. However, if your plant has drooping leaves or the leaves start curling inwards, it’s a sure sign that it needs more water.

As the leaves are sensitive, avoid getting them wet while watering. This can encourage the proliferation of pests and diseases.

Soil

Best Soil
Well-draining potting mix is number one on the list of soil requirements.

To improve drainage in your potting soil, add materials like perlite to potting soil. This not only improves the drainage but increases the airflow in the soil, delivering oxygen to the roots. Also, make sure your chosen container has drainage holes in the bottom so water can drain freely.

Amend two parts potting soil with one part perlite and one part coconut coir to increase moisture retention. Alternatively, look for a specialized houseplant soil mix at your local nursery or online.

Temperature and Humidity

Close Up of Young Silver Leaf Houseplant
Because these plants are native to the tropics, they perform best in warm, humid climates.

Lovers of heat, these tropical plants prefer temperatures of between 65 and 90F. Philodendron brandtianum is frost sensitive and will not cope well with frosty conditions. When growing outdoors in containers, make sure you bring it indoors before the temperature drops below 60F to avoid damage.

Indoors, keep the plants away from radiators, air conditioners, and open doors to avoid drafts. All these will dry out the plants and restrict their growth.

Humidity levels of 60% or higher are ideal, but anything above 50% is suitable.

To improve humidity for these plants, many try misting it occasionally. However, due to the leaf sensitivity, this can invite pests and fungi to breed.

Instead, place pots on trays of pebbles filled with water to improve humidity around the plant, or invest in a humidifier.

Fertilizing

Person Mixing Liquid Fertilizer
Liquid plant food that is diluted in water fed once a month can benefit most houseplants, including the Silver Leaf Philodendron.

While not heavy feeders, you can fertilize once a month with liquid plant food in the growing season of spring and summer. Reduce fertilization in fall and winter.

Avoid overfeeding by reading the instructions on the packaging and applying fertilizer at half strength.

Maintenance

There are several factors of plant maintenance to be well versed in, especially when it comes to more rare versions of houseplants. Providing proper maintenance and care will extend the lifespan of this popular houseplant. Let’s take a look at everything you need to know when it comes to pruning, and plant support for this philodendron.

Pruning

Gardener Pruning Yellow Leaves on Houseplant
Regularly pruning away yellow, brown, or dying leaves can improve the health of your houseplants.

This plant doesn’t require pruning often, but it’s important to remove any dead or dying leaves and stems often. It can also be kept neat and compact through annual pruning.

Don’t remove too much of the plant at one time to prevent shock.

Supports

Vine Climbing Pole
Moss poles are great options for supports to allow your Philodendron brandtianum to climb.

As a climber, this plant can be trained up a support for quicker growth. For Philodendron brandtianum, the best thing to use is moss poles rather than a trellis or metal framework. You can buy these poles at a garden center, or make one yourself.

A moss pole mimics the plant’s natural climbing environment through the porous surface that is easy for a plant’s roots to grab onto. The medium also contains micronutrients that improve overall growth.

Propagation

When propagating this plant, you have several options. You can propagate from cuttings, or you can perform air-layering. Once your plant starts to grow, you’ll want to consider repotting into a larger pot so it has enough room to expand. Let’s take a deeper look.

Propagating From Cuttings

Houseplants Propagating From Cuttings
Cuttings are the easiest and most efficient way to propagate Silver Leaf Philodendron.

The easiest way to propagate Philodendron brandtianum is in water. In fact, the plants can grow in water permanently with some additional fertilizer.

Start by taking stem cuttings of the plant in spring or summer. Using a sharp pair of clean sterilized scissors or secateurs, cut a 6-inch-long piece of stem from a healthy plant.

Cut off the lower leaves, leaving 2-3 leaves at the top of the cutting. Fill a glass or bottle with filtered water, leaving an inch of space at the top.

Cover the top with plastic wrap. Make a hole in the plastic and pop in the cutting, keeping any leaves out of the water. You can add as many cuttings as needed to the glass to grow at the same time. Replace the water every week or so and leave it in a bright warm spot.

In about three weeks, the cuttings will start to form roots. Once the roots are an inch or two long, remove from the water and plant in a container to continue growing.

Air-layering

Air Layering Propagation
Air layering is another technique gardeners use to propagate plants.

Although more technical, you can also try air-layering to propagate these plants. In this method, the stem is wrapped in a growing medium to encourage root growth before being removed from the plant. This increases your chances of success and limits stress for the plant.

On a stem, make a vertical cut about an inch below a node. Use a small handful of damp coconut coir and wrap it around the cut part of the stem. Keep it in place by wrapping it up tightly with plastic wrap and securing with tape or an elastic band.

Keep an eye on the cuttings and add more water if the soil dries out. In 3-4 weeks, the roots will be strong enough to cut off the section of stem and plant in a new pot.

Repotting

Repotting
Fresh soil and nutrients can be achieved every few years through repotting your plant.

Philodendron brandtianum generally requires repotting every 2-3 years into fresh soil with replenished nutrients. You may need to repot sooner if you notice roots growing from the drainage holes or if growth becomes stunted.

Make sure your pot is clean before you start. The new container should have enough drainage holes to prevent root rot after repotting.

Fill the container halfway with soil. Then, remove the plant from its old pot and gently tease out the roots at the bottom. Place in the new pot and fill in with the soil mix. Press down firmly and water thoroughly.

Common Problems

As with all houseplants, you’ll encounter a few common problems. The typical offenders are easy to avoid, and that includes underwatering, overwatering, and light levels. There are also a few basic diseases including leaf spot, and pests like mealybugs. Let’s take a deeper look at the problems you may encounter.

Underwatering

Yellowing Leaf
When your houseplants do not receive the right amount of water, they can become stressed.

As mentioned, Philodendron brandtianum likes a lot of water. Keep the soil a little damp rather than too dry.

If the leaves start browning, it’s a sign that the plant is not getting enough water. Change your watering routine to resolve the problem.

If your leaves have brown tips, the humidity may be too low. Check using a humidity meter and adjust until it is above 50% around the plant.

Overwatering

Trimming Roots
Too much water can cause a multitude of problems for your plants, including fungal diseases and root rot.

Yellow leaves typically indicate a problem with overwatering. This can be caused by several issues:

  • Watering too soon when the soil has not dried out enough.
  • Lack of drainage in the soil, or compacted soil.
  • Lack of drainage holes in the pot.
  • Leaving the pot sitting in water in a pot cover or tray.

Identify the most likely issue and resolve the problem. In cases of root rot, trim the affected roots and repot into fresh soil.

Incorrect Light Levels

Browning Leaf
Bright indirect light is best for your Silver Leaf Philodendron, and too much light can burn the leaves.

Too much direct sun will burn the leaves of your Philodendron brandtianum and can turn them yellow or brown. On the other hand, too little light will compromise growth, also potentially turning the leaves yellow.

Move the plant to a spot with bright indirect light and it should slowly return to normal.

Overfertilizing

Leaves of Houseplant Turning Brown From Over-fertilizing
Curled, browning leaves are an indicator of too much fertilizer in the soil.

If the leaves curl on the ends before turning brown, your plant could be suffering from overfertilization. The extra fertilizer needs to be leached out before the plant recovers.

Run water through the soil several times to remove the excess fertilizer. If too much slow-release fertilizer was used, you will need to repot the plant into fresh soil, removing as much of the soil from the roots before repotting to resolve the problem.

Leaf Spot

Black Spots on Leaves
Not enough airflow for your plants can cause spots on the leaves from fungal growth.

Brown, yellow, or black spots on the leaves are a sign of leaf spot. It is usually caused by too much water on the leaves or crowding with a lack of air circulation.

When water is left on the leaves, bacterial or fungal growth is possible, leaving spots on the leaves. To prevent this problem, don’t water the leaves of the plant and focus on the soil.

Irregular watering could also cause a problem. Make sure the pots are properly drained and that the bottom of the pot does not sit in water.

Cut off all the damaged leaves and stems to encourage new and healthy growth. If the plant is dense, cut back some of the growth to improve airflow between the leaves.

Spider Mites

Spider Mites Close Up on a Leaf
A very common houseplant pest is spider mites, which can be controlled if found early.

These little pests will eat into leaf cells, especially on new leaf growth and the plant will eventually die. Have a look at the underside of leaves for the tell-tale signs of spider mite infestation: webs.

You can use an insecticidal soap or neem oil to control them after giving the plant a good wash with a spray of water to get rid of most of the debris.

For larger infestations, move the plants outdoors and treat with a commercial insecticide.

Mealybugs

Mealybugs Crawling on a Stem
Another common pest for houseplants is mealybugs, which can also be controlled and treated.

Mealybugs can be identified by the fuzzy white powder they carry around while sucking the life out of a plant. They can also cause the plant to wilt and the leaves to yellow. They thrive in warm areas, so look out for them in summer.

Like spider mites, they can be controlled with neem oil or insecticidal soap. You can also use rubbing alcohol to spot treat any visible bugs that may hatch after that. Keep an eye on the plant until it is bug-free.
