Introduction

The Philodendron family boasts an extensive array of species, renowned for their striking, large, green, and glossy leaves. These plants infuse a touch of their native tropical charm into your living space. Famed for their low-maintenance growth, philodendrons come in two primary forms: vining and non-climbing. Vining philodendrons can reach several feet in length and often need a support structure like a trellis or basket to thrive. On the other hand, the non-climbing varieties stand upright, making them perfect as lush, standalone plants in containers. Generally, philodendrons exhibit a rapid growth pattern, adding vitality and greenery to any indoor environment.

Philodendron Care

Philodendrons are excellent as houseplants due to their low-maintenance requirements, yet ensuring the right growing conditions is crucial for their health. To care for your philodendron, recreate its tropical habitat by offering ample warmth and moisture, ideally near a window with plenty of sunlight. However, guard against direct sunlight, which can damage their sensitive leaves.

To keep the leaves of your plant both aesthetically pleasing and healthy, regularly clean them with a damp cloth. In warmer seasons, consider placing your philodendron outdoors in a shaded area occasionally, allowing it to enjoy fresh air and natural light.

Light

This species flourishes optimally in partial sunlight. While philodendrons do require sunlight, they are accustomed to the speckled light found under a tropical canopy, not direct exposure. Indoors, place them near a window where they can receive bright, but indirect, light. Insufficient light can lead to sparse, stretched-out growth with significant gaps between leaves. Conversely, excessive light may lead to simultaneous yellowing of many leaves, a sign of distress. (Note that occasional yellowing of a few leaves is generally part of normal aging.)

Soil

Philodendrons thrive in loosely packed, acidic potting soil that is abundant in organic material, with a key requirement being effective drainage. For potted plants, it is advisable to refresh the soil of your philodendron every two years or thereabouts. These plants are susceptible to the accumulation of salts in the soil from regular watering, which may lead to leaf browning and yellowing. To mitigate this, occasionally water the plant deeply until water flows out of the drainage holes, helping to wash away some of the excess salts. Over time, it becomes necessary to rejuvenate the soil.

Water

To appropriately water your philodendron, assess the soil’s moisture level: the plant needs watering once the top inch of soil feels dry. Philodendrons prefer a balanced level of soil moisture. Both overwatering and underwatering can result in drooping leaves. Therefore, it’s best to determine the need for watering based on the dryness of the soil rather than the appearance of the leaves. Avoid allowing the plant to sit in waterlogged soil, as this can cause root rot. The non-climbing types of philodendrons generally have a higher tolerance for drought compared to the vining varieties. During winter, especially for indoor plants, it’s advisable to reduce the frequency of watering.

Temperature and Humidity

Philodendrons’ tolerance to temperature varies among species, but generally, they should not be exposed to temperatures under 55 degrees Fahrenheit. When indoors, shield them from cold drafts, like those from an air conditioner. These plants favor humid environments, so if you’re in a dry climate, consider increasing the humidity around your philodendron. This can be done by misting the plant with water from a spray bottle every few days. Alternatively, place the plant’s container on a tray filled with pebbles and water, ensuring the container’s bottom is not in direct contact with the water to prevent root rot.

Fertilizer

During spring and summer, nourish your plant with a balanced liquid fertilizer once a month. Adhere to the guidelines on the product label for the appropriate dosage. In the fall and winter, decrease the frequency to every six to eight weeks. Insufficient nutrition can be identified by slower-than-normal growth and unusually small leaves.

Varieties of Philodendron

Prominent lower classifications of philodendron species include:

  • Philodendron scandens: A highly favored climbing variety known for its heart-shaped, sometimes multicolored leaves.
  • Philodendron erubescens: A robust climber featuring reddish stems and leaves. The ‘Pink Princess’ is a notable variant with heart-shaped leaves accented by pink variegation.
  • Philodendron melanochrysum: Distinguished by its striking climbing habit, this plant boasts dark, velvety leaves with a bronze sheen.
  • Philodendron rojo: A compact hybrid that remains small while maintaining its robustness.

Pruning

Should your philodendron vines become overly lengthy or sparse, prune them back with sterilized pruning shears or scissors. Spring or summer is the ideal time for this task. However, it’s perfectly fine to lightly trim your philodendron at any time of the year to eliminate yellowing leaves or manage spindly growth. Always make cuts just above a leaf node. You can then use the stem cuttings obtained from this process for propagation.

Propagating Philodendrons

Propagating philodendrons is a straightforward process, ideal for expanding your collection or sharing with friends. Early spring, as days begin to lengthen, is the perfect time for propagation. Here’s a step-by-step guide on how to propagate philodendrons using stem cuttings and division:

Propagating from Stem Cuttings:

  1. Gather Supplies: You’ll need sterilized pruning shears or heavy-duty scissors, potting mix, a pot, and optionally, rooting hormone.
  2. Cut the Stem: Use the shears to cut a 6-inch section of the stem. Place this cutting in a water container to encourage root growth. Rooting hormone can be added as per instructions, although it’s not always necessary.
  3. Maintain the Water: Replenish water as it evaporates. If the cutting remains in the same water for more than two or three weeks, change it entirely to prevent algae or bacterial growth.
  4. Potting: Once the cutting has developed several roots (typically within two weeks), transfer it to a pot filled with moist soil.

Dividing Your Philodendron:

  1. Preparation: If you plan to divide your plant, water it thoroughly a day before. This helps the plant cope with the stress of division.
  2. Gather Supplies: You’ll need a sharp knife, fresh potting mix, and a new pot.
  3. Division Process: Remove the plant from its current pot and place it on a stable surface. Gently loosen the root ball with your fingers and detach the plantlet, ensuring its roots are intact. If the roots are dense, use the knife to aid separation.
  4. Replanting: Immediately replant the plantlet in a new pot with moist potting mix. This is also an opportunity to refresh the original plant with new potting soil or transfer it to a slightly larger container.

How to Grow Philodendron From Seed

Propagating philodendrons from seed is a more time-consuming method compared to stem cuttings. However, if you’re keen on growing these plants from seeds, here’s a revised process:

  1. Seed Planting: Plant several seeds in a 6-inch pot. Position them about 2 inches apart and plant them around 1/3 inch deep in nutrient-rich soil.
  2. Covering: Use plastic to cover the pot. This helps create a greenhouse effect, aiding germination.
  3. Ventilation and Moisture: Periodically remove the plastic to allow air circulation. Regularly mist the soil to maintain moisture; pre-soaking the seeds is not necessary.
  4. Germination Conditions: Keep the soil temperature between 68 and 73 degrees Fahrenheit. Seeds typically germinate within two to eight weeks under these conditions.
  5. Transplanting Seedlings: Once the seedlings are sturdy enough, transplant each one into its own small pot. This encourages robust root growth and plant development.

Potting and Repotting Philodendrons

To repot a philodendron, choose a container slightly larger than its current root ball, ensuring it has sufficient drainage holes. When you notice roots emerging from the soil surface or protruding from the drainage holes, it’s an indication that the plant needs repotting. Late spring or early summer is the best time for this task. Upgrade to a pot that’s one size larger. Carefully extract the plant from its existing pot and position it in the new one, adding fresh soil beneath and around its sides. Finally, water the plant well to settle it into its new home.

Overwintering

If you’re not residing in a tropical zone, tropical plants must be brought indoors for overwintering. Many tropical species and typical houseplants adapt well to indoor conditions during winter. As daylight hours decrease and temperatures drop, philodendrons require slightly less watering compared to the warmer growing months. Indoor watering should be done only when the soil’s top layer begins to feel dry. Before relocating the plants indoors, use pruners to trim away any yellowing leaves or overextended stems. Additionally, inspect for any signs of mold, decay, or insect infestation.

Common Pests & Plant Diseases

Philodendrons are generally resilient but can fall prey to common houseplant pests like aphids, mealybugs, scale, thrips, and spider mites. Combat these pests using a homemade mixture of water and dish soap, natural insecticidal soap, or horticultural oil. For the dish soap solution, blend 1 tablespoon of dish soap with a quart of water and thoroughly spray the entire plant.

Regarding diseases, philodendrons can be vulnerable to the mosaic virus, recognizable by small yellow spots or patterns on the leaves. In warm weather, move the plant outdoors, away from other plants, to manage this issue. Remove any infected leaves, then rinse the remaining leaves to eliminate dust. To aid recovery, apply a diluted, nitrogen-rich fertilizer to the soil, which will support the plant’s robust growth.

Common Problems With Philodendron

Philodendrons are adaptable and low-maintenance, thriving indoors and propagating with ease. However, they can encounter health problems if their needs for water, sunlight, and soil aren’t properly met. To ensure their well-being, here’s what to watch for and how to address these issues:

Yellowing Leaves

Yellow leaves on a philodendron can be caused by various factors including using overly cold water, insufficient sunlight, or too much direct light. Yellowing of the older leaves often indicates under-watering, while yellowing at the lower, younger leaves might suggest overwatering. Adjusting these conditions usually helps the plant recover.

When fertilizing your philodendron, it’s important to first water the soil. Then apply a diluted fertilizer solution, followed by another round of watering. This method prevents the plant’s roots from being damaged by the fertilizer’s chemicals, which can also lead to yellowing of the leaves.

Yellowing and Rotting Smell

Rapid yellowing of leaves in your plant may indicate root rot. Prompt action could save the plant. Check for a foul smell in the soil or examine the roots to assess their condition. If root rot is present, trim away the black, mushy parts of the root, preserving the healthy white or yellow sections. Then, replant these in a new container with fresh soil.

Browning Leaves

Browning edges on your plant’s leaves suggest that the water temperature may be too cold, causing shock. Additionally, if the leaves turn brown and mushy, this is typically a sign of overwatering. When you notice brown leaf edges beginning to curl, it usually means the plant requires more water and less sunlight. Adjust your care routine to these needs.

If the leaf tips are turning brown with yellow surrounding areas, it’s a sign that the plant could benefit from increased humidity. To address this, you can mist the leaves or set the plant’s container on a tray filled with pebbles and water. Ensure that the base of the plant is just above the water level, not submerged.

Leaves Falling Over or Drooping

Healthy snake plant leaves typically grow upright and remain erect. However, excessive watering, inadequate light, or inappropriate potting soil can result in leaves drooping or bending over. To address this issue, relocate the plant to a brighter spot, reduce the frequency of watering, and consider repotting it with a well-draining soil mix.
