Philodendron: The Complete Guide
to Successful Care
A close cousin of the monstera within the Araceae family, the philodendron captivates with its lush foliage and ease of care. Whether it's a climbing variety guided on a support or a trailing variety in a hanging basket, it adapts to almost any indoor environment, including those with less natural light.
When well-established, a philodendron can develop dense and generous foliage, with stems that climb or trail for over a meter in a single growing season — enough to quickly transform an empty corner of a room into a true green oasis.
Plant ID Card
Ideal Light
One of the most light-tolerant plants
Philodendrons thrive in bright, indirect light, but they also tolerate lower light conditions much better than most large-leaved plants, making them an excellent choice for less luminous rooms. However, avoid direct sunlight during the hottest hours, as it can scorch their delicate leaves.
Watering
Regular watering, without excess
Allow the top 2 to 3 centimeters of potting mix to dry out between waterings, generally every 7 to 10 days in summer. The philodendron quickly reacts to overwatering with yellow leaves, and to prolonged lack of water with leaves that droop slightly before recovering after the next watering.
"A well-adjusted philodendron asks for almost nothing —
that's precisely what makes it a safe bet."
Substrate and Repotting
A rich but airy potting mix
A quality universal potting mix, possibly lightened with a bit of perlite or pine bark, is perfectly suitable. Repot every 1 to 2 years, or as soon as roots start to emerge from the pot, into a container slightly larger than the previous one.
Fertilization
Regular feeding during peak season
Fertilize every 2 to 4 weeks during the active growth period, and suspend all feeding in winter, when the plant doesn't need it.
Tropical Green Plant Fertilizer 250 ml
Promotes dense foliage and intense color, suitable for philodendron during its active growth period.
Routine Care
Support for climbing varieties
Climbing varieties greatly benefit from a moss pole or wooden stake, which allows them to develop larger leaves by clinging to a support, just as they would against a tree trunk in their natural habitat. Regularly dust the foliage with a damp cloth to help it capture maximum light.
Propagation by Cuttings
Philodendrons are very easy to propagate from a simple stem section with a node and a leaf. Consult our guide how to propagate an indoor plant for the complete method — an excellent way to get new plants at a lower cost or to give as gifts.
⚠ Toxicity for pets and young children
Like monstera, philodendron contains irritating calcium oxalate crystals if ingested. Place it out of reach of pets and young children. For a risk-free home, consult our selection of non-toxic plants for pets.
Common Problems
Philodendrons are generally easy to care for, but some signs deserve your attention:
| Symptom | Probable Cause |
|---|---|
| Yellow leaves | Overwatering most often |
| Stretching stems, sparse leaves | Lack of light (etiolation) |
| Brown tips | Air too dry or irregular watering |
| Falling leaves | Watering or temperature stress |
| Fine webs under leaves | Spider mites, especially in dry air |
For a more precise diagnosis based on your symptoms, consult our dedicated guides: yellow leaves, falling leaves, brown tips or spider mites.
Mistakes to Avoid
- ❌ Overwatering, the most common cause of yellow leaves on this plant
- ❌ Leaving a climbing variety without a support, which results in messy stems and smaller leaves
- ❌ Ignoring progressive etiolation, thinking "it's normal for it to grow like that"
- ❌ Repotting in a pot that is too large, which retains excessive moisture
- ❌ Systematically confusing philodendron and pothos, which have similar but not identical needs
Frequently Asked Questions
Short answers to the most common questions we get about philodendrons.
What is the difference between philodendron and pothos?
The two look very similar, but philodendrons generally have thinner, shinier leaves, while pothos often have thicker and sometimes variegated foliage. Their care needs are very similar.
Why are my philodendron's stems stretching out?
This is the classic sign of a lack of light: the plant stretches its stems to seek a stronger light source. Move it closer to a window to encourage more compact foliage.
Can you grow a philodendron in water?
Yes, some varieties adapt well to prolonged cultivation in water, provided the water is changed regularly. However, growth is generally slower than in potting mix.
Should you prune a philodendron?
Light pruning in spring helps to densify the foliage and limit overly long and bare stems at the base. It's not essential, but it's beneficial once a year.
Is philodendron toxic to cats and dogs?
Yes, like most Araceae, it contains irritating crystals if ingested. It's best to place it out of reach if you have curious pets at home.
How often should I repot a philodendron?
Every 1 to 2 years is usually sufficient, or as soon as the roots are clearly growing out of the pot or growth slows down abnormally despite good care.
Why do the leaves remain small?
Lack of light, depleted substrate, or a pot that has become too small are the most frequent causes of leaves remaining stunted compared to their usual size.
In summary
- ✅ Indirect light, tolerates lower light than average
- ✅ Water when the top 2 to 3 cm of potting mix are dry
- ✅ Fertilize from March to September
- ✅ Repot every 1 to 2 years
- ✅ Support recommended for climbing varieties
