Philodendron Grazielae Care

Philodendrons of all kinds make fantastic houseplants, but the rare Philodendron grazielae is an especially beautiful plant to grow indoors. With its dark green, glossy, heart-shaped leaves and climbing growth form, it adds a tropical ambience to any room it grows in.

Philodendron grazielae needs warm, humid growing conditions to thrive. Grow it in bright, indirect light in a soil mixture that drains freely. Give this climber a moss pole to support upward growth. Water it regularly, but be wary of overwatering. It needs repotting every 1 to 2 years.

By mimicking the conditions that it grows in naturally, we can keep our Philodendron grazielae healthy and happy. They are simple plants to care for once you understand their basic needs and how to maintain them.

Native Habitat Of Philodendron Grazielae

This philodendron is native to the tropical rainforests of South America. Philodendron grazielae naturally ranges from Peru all the way to Northern Brazil. This area has a hot, humid climate, so indigenous plants are adapted to these conditions.

Philodendron grazielae grows in the forest mid-story, climbing up other trees to compete for light. It is adapted to growing in the dappled shade of larger trees of the forest.

The soils that this philodendron naturally grows in are very high in organic matter, typical of forest floors. Philodendron grazielae is a terrestrial plant, but as it grows taller, it develops aerial roots to capture water from the air.

Philodendron Grazielae Is Simple To Care For

Some beginner plant parents are daunted by the idea of caring for such a rare philodendron species. They cost a bit more than the more common species. But Philodendron grazielae is just as simple to care for as any other philodendron.

Philodendron grazielae’s basic care requirements are summarized by the table below:

SoilRich, loamy soil with excellent drainage.
LightNo direct sunlight, just bright, indirect shade.
WaterOnce per week. It needs evenly moist soil, but allow for it to dry out between watering.
Temperature range70°F – 80°F (21°C – 26°C).  Sensitive to cold temperatures (below 60°F) and frost.
HumidityHigh humidity environment – between 60 and 80%.
SupportClimber – needs a moss pole for support.
FertilizerFeed monthly using organic liquid fertilizer, diluted to half strength.
RepotOnce a year or every second year.

Growing Philodendron Grazielae Indoors

Philodendrons are the perfect houseplants because they are shade loving. In most places, they can only be grown indoors, as they are only hardy in USDA zones 9 to 11.

Provide your climbing philodendron with a moss pole for support. These plants can grow 3 to 4 feet tall indoors.

Optimal Lighting Conditions

They grow happily in an east, northeast, or north-facing window. Position them 3 to 6 feet from the window to avoid exposure to harsh, direct sunlight.

If you want to grow this philodendron in a south or west-facing window, make sure you have some sheer drapes or blinds to protect your plant from getting sunburnt. The leaves turn yellow if they get too much direct sunlight.

Best Temperature Range

Grow this plant in a room where the temperature stays more or less constant. This philodendron is happiest between 70°F and 80°F (21°C to 26°C).  As a plant from the tropics, it can tolerate higher temperatures between 90°F and 95°F.

However, these plants are highly sensitive to cold and frost. They struggle to grow in temperatures between 50°F and 60°F and will die if they are exposed to frost.

Optimal Humidity Range

As this philodendron thrives in a humid environment, growing it inside a greenhouse is optimal because you can increase the humidity to 60% or even 80%. These kinds of humidity levels are a bit high for the average room in your house.

Luckily, Philodendron grazielae can still grow at lower humidity levels. To boost the humidity in the room, use a humidifier, or mist the foliage with water. You can also place a saucer containing wet pebbles under the pot to provide more humidity in the root zone.

Best Soil Type

Philodendron roots must be exposed to air. Therefore, they require a well-aerated, free-draining potting mixture. Because they naturally grow in forests, they also need soil that is rich in organic matter.

The ideal potting soil for Philodendron grazielae is equal parts regular potting soil and perlite, mixed with a few handfuls of compost and coco peat.

The perlite creates good drainage conditions in the soil, allowing excess moisture to escape, while the compost and coco peat hold onto moisture to hydrate the plants’ roots.

Maintaining and Propagating Philodendron Grazielae

Keeping your Philodendron grazielae in good condition is easy once you know how much food and water to give them, how often to repot them and how to propagate them.

Watering Requirements

Watering Philodendron

Like most plants, Philodendron grazielae needs more water during the growing season (spring and summer) than in winter. Water every week or every second week, depending on your climate, and only once a month during winter.

Philodendrons are highly susceptible to root rot from overwatering. It is important to check that the top few inches of soil have dried before watering again. To be very sure, use a soil moisture meter.

How Often To Feed Philodendron Grazielae

Philodendron grazielae is very sensitive to fertilizer and can easily suffer from nutrient burn. It is not essential to feed this plant, but if you want to boost its growth, feed it monthly during the spring and summer.

Use a general-purpose organic liquid plant food and always dilute it to half the recommended strength to avoid fertilizer burn.

As these plants go dormant during winter, only feed it every 2 to 3 months during this time.

When To Repot Philodendron Grazielae

This species of philodendron is relatively fast-growing, especially if you feed it regularly. Every year to two years, you will need to pot your Philodendron grazielae into a bigger container and replace its soil.

When repotting, the new pot should be 2 inches larger than the diameter of the root mass. Avoid choosing a pot that is too large (5 or 10 inches wider than the roots).

Propagate Philodendron Grazielae

You can propagate these rare plants easily in the spring by taking stem cuttings.

  • Use a sterilized, sharp knife to cut off bits of stem 3 to 5 inches long.
  • Look for sections of the stem with 1 or 2 leaf nodes – this is where roots will grow from.
  • Place the cuttings in water for 2 to 3 weeks and keep them in a warm place with bright shade. You will need to replace the water every couple of days
  • Once the roots are an inch in length, pot the cuttings into small pots with a well-draining potting mixture.
  • Grow your cuttings in a warm spot in bright, indirect sunlight.

Pests and Diseases That Affect Philodendron Grazielae

These plants do not often have issues with pests or diseases, but potentially aphids, mealybugs, and scale can affect your philodendron. These pests suck the plants’ sap, causing infection and stunting the plant’s growth.

Aphids are tiny, green insects that secrete a sticky, sugary liquid called honeydew. Most often, they are found on plant growing tips.

Mealybugs are tiny, pink, soft-bodied insects that are easily identified as they are covered in white fluff. Scale is visible as slightly raised, oval-shaped brown spots on plants leaves and stems.

Fortunately, it is easy to remedy these problems. Neem oil or insecticidal soap will both work to get rid of aphids, mealybugs, and scale.


Philodendron grazielae is a tropical South American plant that makes a wonderful houseplant. While it is rarer and more expensive than other philodendrons, it is just as easy to care for.

It thrives in warm, humid conditions, so keep them in a room that stays between 70°F – 80°F (21°C – 26°C) and water them regularly. They need soil with excellent drainage to prevent root rot.

It does not have major problems with pests and diseases. Scale, aphids, and mealybugs can affect Philodendron grazielae, but these pests are easy to control using neem oil or insecticidal soap.
