Philodendrons are popular houseplants due to their attractive foliage and adaptability to various growing conditions. One fascinating aspect of their nature is how rapidly they grow. Whether you’re a veteran houseplant enthusiast or someone new to growing indoor plants, understanding the growth rate of philodendrons is essential to optimizing their care and ensuring a healthy, thriving plant.

With ideal conditions, philodendrons can display a surprising growth rate, sometimes adding 4 inches (10cm) per week during active growing seasons such as spring and summer. This applies to both vining and upright philodendrons, with growth typically slowing down after about five years. Much of this rapid growth depends on providing proper care, including adequate light, humidity, and nutrients.

While the fast-growing nature of philodendrons may seem like a blessing, it’s important to remember that maintaining their health requires regular care, such as pruning and repotting when necessary. By understanding the factors impacting their growth and how to optimize their environment, you’ll be able to enjoy these eye-catching plants as they transform your space.

How Fast Do Philodendron Grow

Philodendrons are known for their relatively fast growth when given proper care and the right conditions. These versatile plants can grow at a rate of 4 inches (10cm) per week during their active growing seasons, which include spring and summer. Keep in mind that this growth rate applies to both the vining and upright varieties of philodendrons.

To ensure optimal growth for your philodendron plant, consider providing a warm and humid environment. This will encourage rapid growth and a healthier plant. However, be aware that low temperatures and sudden drops in humidity levels can negatively impact growth, causing it to slow down.

There are several factors that influence the growth rate of a philodendron, such as:

  • Adequate lighting: While philodendrons can tolerate low light conditions, providing them with bright, indirect light will better promote growth.
  • Proper watering: Make sure to keep the soil consistently moist but not waterlogged. Allowing the top inch to dry out between waterings is a good guideline.
  • Fertilizing: Feeding your philodendron with a balanced, liquid, houseplant fertilizer during the active growing seasons will support their growth and overall health.
  • Pruning and Maintenance: Regularly trimming older or yellowing leaves will encourage new growth and give the plant a fuller, bushier appearance.

Vining philodendrons also produce aerial roots, which grow quickly alongside their impressive 10cm per week growth. This rapid rate allows the plant to spread throughout your home in a relatively short amount of time, making it an excellent choice for adding lush greenery to your living space.

In summary, by providing your philodendron with the right conditions, care, and maintenance, you can enjoy watching its rapid growth throughout the spring and summer seasons. Remember to keep the plant in a warm, humid environment, and give it ample sunlight, water, and nutrients to support its growth successfully.

Factors Affecting Philodendron Growth

In this section, we’ll discuss various factors that can influence the growth rate of philodendron plants. By understanding and optimizing these factors, you can ensure your plant’s healthy and rapid growth.


Philodendron plants need proper lighting to grow well. Although they can tolerate low light levels, providing them with bright, indirect light will promote faster growth. Be cautious of direct sunlight, which can burn the leaves and damage the plant.


Proper watering is crucial for philodendron growth. These plants prefer consistently moist soil, but overwatering can lead to root rot and stunt their growth. On the other hand, underwatering can cause the plant to become stressed, resulting in slower growth. Maintain a balanced watering routine to keep your philodendron healthy and growing at an optimal speed.

Different Types of Philodendron

Philodendrons are a diverse group of plants known for their attractive foliage and relatively fast growth. With over 61 different types of Philodendron, they can be broadly classified into two categories: Climbing Philodendrons and Non-Climbing Philodendrons.

Climbing Philodendrons

Climbing varieties of Philodendron are popular for their ability to gracefully climb or trail, making them perfect for hanging baskets, trellises, or supported indoor plants. Some well-known climbing Philodendrons include:

  • Heartleaf Philodendron: This variety is recognized by its small, heart-shaped, jade green leaves, and it’s an easy-to-grow indoor plant that is perfect for hanging baskets and planters.
  • Philodendron Micans: Featuring velvety, heart-shaped leaves that display a range of colors from bronze to dark green, this plant adds an elegant touch to its surroundings.
  • Philodendron Brasil: This variant has striking variegated leaves with splashes of yellow and cream, making it a visually appealing choice for plant enthusiasts.

Climbing Philodendrons can grow 2 to 4 inches per week during their active growing seasons, which are summer and spring.

Non-Climbing Philodendrons

Unlike the climbing varieties, non-climbing Philodendrons have an upright growth habit and a more bush-like or tree-like appearance. These plants also grow relatively fast but tend to be slower than their climbing counterparts. Some popular non-climbing Philodendrons are:

  • Philodendron Xanadu: This variety has deeply lobed leaves and a compact growth habit, making it perfect for indoor containers or small outdoor spaces.
  • Philodendron Birkin: Recognizable by its white-striped, dark green leaves, Philodendron Birkin adds a unique flair to any plant collection.
  • Philodendron Rojo Congo: As the name suggests, this plant boasts red stems and beautiful green leaves that darken with age, creating a striking contrast.

Non-climbing Philodendrons, like the tree-like Philodendron, can grow up to 3 ft outdoors but will have restricted growth indoors due to the pot size. They are excellent specimens for evergreen, leafy indoor plants.

Both climbing and non-climbing Philodendrons are capable of fast growth, making them a rewarding choice for plant lovers who want to see impressive progress in their collections. Keep in mind that their growth rate is significantly influenced by factors such as proper care, environment, and pot size.

Maximizing Philodendron Growth

Pruning Techniques

Proper pruning techniques are essential for encouraging your philodendron to grow faster and maintain its shape. Regularly remove any dead or yellowing leaves to promote new growth. Focus on trimming back any excessively long vines, as this will help redirect the plant’s energy towards producing new foliage. Be sure to use clean, sharp scissors or pruning shears to avoid damaging the plant, and make angled cuts close to the main stem.


Philodendron propagation is another useful strategy for boosting the overall growth rate of your plant. By creating a new plant from existing stem cuttings, you can increase the size and distribution of your philodendron collection. Follow these simple steps:

  1. Choose a healthy vine with at least two to three leaves, and make a clean cut below a leaf node.
  2. Remove the lower leaves, leaving about an inch of stem below the node.
  3. Place the cutting in a jar of water or directly into moist potting soil, ensuring the node is submerged or covered.
  4. Keep the cutting in a warm, bright location, but avoid direct sunlight.
  5. Monitor the propagation process, and expect new roots to appear within one to two weeks.

By providing your philodendron with proper care, such as appropriate lighting, regular watering, and a well-draining soil mix, you can further enhance its growth rate. During its active growing season in spring and summer, philodendrons can grow 2 to 4 inches per week, so adopting these strategies can significantly contribute to the health and size of your plant.

Common Problems and Solutions

Yellow Leaves

One common problem that philodendron plants face is yellowing of leaves. This can be caused by a variety of factors, such as overwatering, insufficient light, or poor soil quality. To address this issue, ensure your philodendron receives adequate indirect light and water only when the soil is 50-75% dry. Additionally, using well-draining, nutritious soil can help prevent yellow leaves. It’s also essential to maintain an ideal temperature for your philodendron, which is between 70-80°F.

Another possible cause of yellow leaves is root rot. This serious issue is often caused by overwatering or bad drainage. If your philodendron’s leaves are yellowing, blackening, or drooping, inspect the roots and take action to improve drainage or reduce watering.


Philodendrons may occasionally be affected by pests, such as mealybugs, spider mites, and aphids. To help prevent and treat these infestations, follow these steps:

  1. Regularly inspect the plant for visible signs of pests.
  2. Prune any affected leaves and dispose of them properly.
  3. Clean the plant with a mixture of water and mild dish soap, thoroughly rinsing afterward.

For severe infestations, you may need to use insecticidal soap or horticultural oil as a last resort. Moreover, maintaining proper plant care—such as ensuring adequate light, water, and appropriate temperature—will help keep your philodendron healthy and less susceptible to pests.


In summary, philodendrons are fast-growing houseplants, with some varieties growing up to 10 cm a week during their active growing seasons, which are spring and summer. However, factors such as temperature, humidity, and the type of philodendron can significantly affect the growth rate of these plants.

Providing a warm and humid environment can promote robust growth, while low temperatures and sudden drops in humidity levels may slow down their growth. It is worth noting that different types of philodendrons have varying growth rates. For instance, Philodendron Hope can grow up to five feet a year, while Philodendron Xanadu can grow up to four feet in a year.

To ensure optimal growth, it’s essential to take care of your philodendron properly. This includes fertilizing during the growing season once per month and reducing it to once every 6 to 8 weeks during the dormancy period. Remember to maintain appropriate soil moisture levels, as these plants are quite thirsty but cannot tolerate wet soil for extended periods.

Incorporating proper plant care techniques, selecting suitable varieties, and providing the ideal environment will help your philodendrons grow faster and healthier, adding beauty and greenery to your living spaces.
