Philodendron Burle Marx: Care and Growing Guide

Maintaining a tropical climate is the first step towards keeping your Burle Marx Philodendrons happy.

Additionally, the plant is a quick grower, and you must keep a frequent checkup routine.

Image illustrates basic care tips for Burle Marx
Philodendron Burle Marx is a tropical plant that needs specific tropical conditions to keep itself healthy.

So, improper lighting and temperatures, irregular watering and humidity, poor soil and fertilizer, and insufficient pruning and repotting can impede growth.  

1. Sunlight and Temperature

Burle Marx Philodendron likes to stay away from direct sunlight. But, a couple of hours of morning sunlight causes no harm to the plant.

Sunlight is vital for the plant as a heat source, as Burle Marx is sensitive to cold spells.

Moreover, intense or bland sunlight can increase or decrease the surrounding temperature.

Burle Marx Philodendrons require 4-6 hours of bright indirect sunlight daily and surrounding temperatures of 60-79°F.

Unequal lighting regimes can affect the surrounding temperature dynamics and deteriorate the plant’s health.

Signs of Extreme Light and Temperature

  • Tips and peripheral burns in leaves
  • Leaf curls (inward or outward)
  • Brittle leaves and burn marks in stem or petioles
  • Pale or yellow patches on the leaf surface
  • Sagging leaves and dry soil due to water loss

In low light, the leaves of Philodendron Burle Marx stretch out and become lean.

Signs of Less Light and Temperature

  • Discoloration of leaves (green to yellow)
  • Droopy foliage (leaves and petioles)
  • Leaf and flower fallouts
  • Gangly leaves, stems, and petioles

Tips to Provide Adequate Light and Temperature

  • Place the plant near an east-facing window for 4-6 hours daily.
  • If you keep the plant in a room with southern sun exposure, fix it about 3-5 feet from the nearest window.
  • Use shades to protect the plant from direct sunlight outdoors.
  • Keep the plant away from north-facing drafty windows, heaters, vents, or temperature-changing outlets.
  • Cover the plants with frost blankets in winter at night to prevent frost injury.

2. Water and Humidity

Philodendrons reside in warm and wet tropical rainforests and receive frequent rain showers. 

Moreover, warm temperatures evaporate the soil water, creating a humid environment where the plant grows upstanding. 

During spring and summer, the growing season, water once a week, and during winter, watering them once in two weeks is enough. Also, provide humidity levels of around 60-70%.

Although the plant can tolerate high humidity, it barely makes out from the declining humidity levels.

Also, over or underwatering keeps the soil soggy or dry for too long, which is stressful for the plant.

Underwatering Issues

  • Progressive yellowing and browning of leaves
  • Crunchy leaf edges and brown spots on stems
  • Wilting leaves and petioles
  • Cracks on the topsoil

Overwatering Issues

  • Foul smell from the soil due to root rot
  • Mushy or soggy soil
  • Limpy wet leaves
  • Yellowing and browning of leaf surface

To check for root rots, unpot the plant from its old container, inspect for healthy, light-tan roots, and remove root rots.

Signs of Low Humidity

  • Fewer and small-sized blooms and leaves
  • Shrievling and curling of foliage
  • Bud and flower drops

Tips to Provide Adequate Watering and Humidity

  • Inspect the soil regularly and water when the top 1-2 inches of the soil is completely dry.
  • Use a soil moisture sensor to measure moisture and humidity.
  • Change the soil if it smells foul.
  • Mist the leaves occasionally in summer.
  • Wipe the water drops from the leaves and prevent watering in the morning or evening.
  • Use the bottom watering approach to saturate the potting soil with moisture.
  • Group the plants together or keep the plants in a ventilated bathroom for optimal humidity.

3. Soil and Fertilizer

Over time, soil quality may degrade, become clumpy and compact and lose all the nutrients.

So, Philodendron Blue Marx requires good quality soil with added minerals that can replenish the lost nutrients.

Offer a seeping but water-retentive substrate with pH levels between 5.6 to 6.5. Also, fertilize the plant biweekly with balanced liquid feed in spring and summer.

Blue Marx are heavy feeders, but in fall and winter, the plant sleeps and doesn’t need any feeding.

Heavy fertilizer application during this time can do more harm than good, affecting the leaves and stopping nutrient uptake.

Overfertilization Issues

  • Fertilizer burns on the leaves and roots
  • Accumulation of mineral salts on the topsoil
  • Obstruction in nutrient uptake from the roots

Under fertilization Issues

  • Change in leaf colors
  • Stunted growth
  • Poor production of blooms and leaves

Tips for Proper Fertilization and Soil

  • Leach the excess salts by washing the soil 4-5 times with distilled water.
  • Dilute the fertilizer concentrate to half-strength.
  • Water the plant before applying the feed.
  • Add pebbles at the pot’s base to provide extra drainage.
  • Toss away stagnant water from the basal tray before and after watering.

You can prepare a homemade potting mix by mixing peat moss, pine bark, organic perlite, horticultural charcoal, and worm casting in the ratio of 2:1:1:1:1.

4. Casual Pruning

Philodendron Burle Marx is a speedy grower. With each new growth, the older parts become damaged or discolored.

Also, as the plant ages, it becomes weak and comes in a fistfight with pesky bugs (aphids, thrips, mealybugs, and white flies) and diseases (root rot and leaf spots).

To prune Blue Marx, take sterilized pruners and make clean cuts at the base of the infected leaves.

However, you can also remove the naturally dead leaves from the plant, or they can be a medium for new diseases.

Removing the extra weight (damaged parts) assists the plant in attaining a compact and bushy form.

The normal time to prune the plant is in early spring when the plant is actively growing.

Additionally, to keep diseases and pests out of the bay, use neem oil and broad-spectrum fungicides at the site of infection.

Spray the fungicides on the infected plants every 7-14 days until the threat disappears.

Also, use the neem oil in the morning or evening so that the daytime sun and oil cannot burn the leaves.

You can also hang sticky traps around the plant to keep the hovering pets out.

5. Annual Repotting

Repotting is necessary for Blue Marx as the plant quickly becomes root bound owing to its fast-growing habit.

Choose a 2-3 inches larger terracotta pot with bottom drainage holes and fresh potting mix to repot the plant in late winter or early spring.

Additionally, causal repotting can stress the plant and give the plant a hard time to rebound.

Burle Marx is a fast-growing variety of Philodendron that needs annual repotting when its roots become crowded and leggy, covering all the space of its pot.

When root-bound, Philodendrons can show the following signs of strain.

  • Roots pushing out from the drainage holes of the pot.
  • Cuddling of the roots on the topsoil.
  • Cracks or bulges on the container.
  • Stunted growth and quick seepage of water from the soil.

If your Philodendrons show these signs, step up to repot the plant.

Philodendron Burle Marx: All About the Growth

Burle Marx is a low-growing variety of clumping Philodendrons growing about 2 feet tall and 3-4 feet wide.

The plant catches a quick growth (2-4 inches a week) in growing seasons and begets lush foliage in no time.

Due to their growth, sometimes they tend to climb and crawl over as they cannot support their growth.

Moss pole offers hydrating support for the leaves, stems, and roots of Burle Marx when they spire upwards.

It hails from the South American Rainforests and is largely grown for its oblong cordate (heart-shaped) leaves.

When young, the glossy leaves are bright-yellow with a tint of lime green but eventually get darker green on top as the plant matures.

However, as it becomes dormant, you will barely see any growth in the plant in the fall and winter.

But before getting a winter sleep, the plant shows a good flush of flowers in summer.

Interestingly, there is another variety of this plant known as Philodendron Burle Marx variegated, that entirely resembles with it, except the lime-green variegations throughout the leaves.

The flower is called an inflorescence, with leafy whitish-green Spathe and cylindrical, curved creamy white Spadix, resembling the flowers of another Philodendron variety, Philodendron rugosum.

Spadix consists of many tiny flowers that later transform into berries after pollination. But, Spathe performs the vital job of luring the pollinators.

Toxicity of Philodendron Burle Marx

Almost all Philodendrons including Philodendron Burle Marxa Fantasy are toxic to pets due to the presence of calcium oxalate crystals in their parts.

Poison Control mentions that Philodendrons and their varieties are toxic to cats, dogs, and horses.

Although not so severe, the calcium oxalate in the plant parts can also irritate humans.

In pets, biting the plant parts can cause oral, skin, and ocular irritations, swelling of the esophagus, excessive drooling, vomiting, and diarrhea. 

Humans can also catch blisters or rashes when contacting the sap.

To protect your pets, wrap a cone around your pet’s neck or keep the plant on top shelves or sturdy tables.

You also wash the mouth parts with milk to subside the severity of the symptoms.

However, if first aid doesn’t work, call the following helpline numbers to register an emergency. 

Propagation Methods for Philodendron Burle Marx

The easiest and most highly used method is stem cuttings, air layering, and seeds.

However, spring or early summer is the best time to propagate Burle Marx.

1. Propagate Via Stem Cutting

  • First, cut a healthy 2-4 inches long stem about 1 cm below the node containing a node, aerial roots, and at least one leaf.
  • Callous the cutting for 7-10 days in a warm location.
  • Now, place the stem in a jar with rooting hormone solution, immersing node, and aerial roots without plunging the leaves.
  • Change the water every 3-5 days when it turns murky.
  • Cover the cutting with a humidity dome or plastic wrap to secure humidity.
  • Place the setup near an east-facing window for 4-6 hours daily at around 60-79°F.
  • Then, the cutting will have at least 5 cm long roots in 1-3 weeks, which can now be transferred to a pot with a suitable potting mix.
  • Place the pot in a north or east-facing window and provide feed and water when the plant grows new leaves.

2. Propagate Via Air Layering

  • Use a sterilized knife to make a 5 cm-long deep wound in the stem.
  • The wound should be kept open for roots to grow so you can push a toothpick into the wound.
  • However, if a node already has healthy aerial roots, you can skip this step and use the node for air layering.
  • Tie a handful of sphagnum moss around the wound or aerial roots.
  • If the moss seems dry, add water by opening the wrap.
  • Plant the roots in a well-draining potting mix when they are at least 3-5 cm long.
  • After planting, locate the pot in an east-facing window and provide feed and water as a normal mature Burle Marx after they grow new leaves.

3. Propagate Via Seeds

If you have a Philodendron Burle Marx, wait for them to bloom, collect seeds by summer’s end, and sow them to grow more plants.

  • Separate the seeds from the pulp and soak them in lukewarm water for 24-48 hours of treatment.
  • Plant the seeds 1 cm deep and 5 cm apart in a starter potting mix.
  • Cover it with a humidity dome and set the container in bright sunlight.
  • Maintain a temperature of around 70°F using a heating mat.
  • Use a spray bottle to spray water on the soil to keep it wet (not soggy) once a week.
  • Within a month, the seeds will germinate and be ready to be transplanted into a bigger pot.
