Philodendron Care Guide: Trailing and Upright Varieties Compared

Two Growth Habits, One Plant Family

The genus Philodendron contains more than 450 species, but for indoor cultivation they fall into two broad categories that share the same ancestry but look completely different. Trailing or vining philodendrons — heartleaf (P. hederaceum), 'Brasil', 'Lemon Lime', and the much-sought-after P. micans — have small heart-shaped leaves on long cascading stems that can trail from a shelf or climb a moss pole. Self-heading or upright philodendrons — P. gloriosum, P. selloum (now P. bipinnatifidum), P. melanochrysum, and P. birkin — grow as a rosette or climbing stem with large dramatic leaves held horizontally or upward.

Despite their different shapes, both types share the same care preferences: bright indirect light, a chunky well-draining aroid mix, consistent moisture without sogginess, and moderate to high humidity. Once you understand one philodendron, you understand almost all of them.

Light: Bright Indirect Is Universal

All philodendrons want bright indirect light. East and west windows are ideal; a few meters back from a south window also works. Direct sun burns the leaves within hours, producing pale brown scorch patches that never recover. In very low light, trailing philodendrons survive but produce widely spaced small leaves, while self-heading varieties stop growing entirely and may slowly decline over a year or two.

Variegated philodendrons like 'Brasil' and 'Birkin' need slightly more light to maintain their variegation — in dim conditions they revert to plain green. If you notice new leaves coming in less variegated, gradually move the plant to a brighter spot. Conversely, too much direct sun can bleach the cream portions of variegated leaves, so find the balance of bright but indirect.

Watering Strategy

Water when the top 3–5 cm of soil feels dry. For trailing philodendrons in smaller pots, this is typically every 5–7 days in summer and every 10–14 days in winter. For self-heading varieties in larger pots, the interval is longer — every 10–14 days in summer, every 3 weeks in winter. Always water thoroughly until moisture runs from the drainage holes, then empty the saucer.

Philodendrons tolerate drying out far better than staying wet. If you forget to water for an extra week, the plant will droop slightly and recover within hours of watering. If you water too frequently, the leaves turn yellow evenly across the plant and the lower stems become soft. When in doubt, wait another two days before watering.

Soil: The Chunky Aroid Mix

Use the same chunky aroid mix described in our aroid soil recipe — 2 parts orchid bark, 2 parts perlite, 1 part coco coir, plus small amounts of charcoal and worm castings. The chunky structure prevents root rot, allows roots to breathe, and supports the mycorrhizal fungi that philodendrons naturally associate with. Avoid dense potting soil from a generic bag — it is the number-one cause of slow decline in established philodendrons.

Repot trailing philodendrons every 1–2 years, when roots are visible at the drainage holes. Self-heading varieties grow more slowly and only need repotting every 2–3 years. Always go up just one pot size — too-large pots stay too wet and lead to root rot. Spring and early summer are the best times to repot.

Humidity and Temperature

Philodendrons evolved in tropical rainforests and appreciate 50–70% humidity. They tolerate typical home humidity of 40% but grow more vigorously with more moisture in the air. Self-heading varieties with large soft leaves (P. gloriosum, P. melanochrysum) are particularly sensitive to dry air and develop brown crispy edges when humidity is too low.

Increase humidity with a humidifier placed within 2 meters of the plants, or group plants together to create a localized humidity pocket. Pebble trays under pots help modestly. Avoid misting the leaves directly — water droplets sitting on large leaves can cause fungal spotting.

Support and Training

Trailing philodendrons look beautiful cascading from a shelf, but the same plant trained up a moss pole produces leaves that are 2–3 times larger and more dramatic. To train a vining philodendron, attach a sphagnum moss pole to the pot and gently tie the stems to the pole with soft plant ties or twine. Keep the moss pole consistently moist by misting it daily or using a self-watering pole. The aerial roots will grow into the moss, and within months the new leaves will be substantially bigger.

Self-heading philodendrons like P. gloriosum grow as a creeping rhizome that crawls along the soil surface. Do not bury the rhizome — instead, top-dress with sphagnum moss to keep the rhizome humid and encourage roots to grow down into the soil below. P. bipinnatifidum and P. selloum grow as upright plants and eventually need a sturdy stake or moss pole to support their heavy leaves and thick stem.

Propagation

Trailing philodendrons are among the easiest plants to propagate. Cut a stem just below a node (the bump where a leaf and aerial root emerge), remove the lowest leaf, and place the cutting in water or moist perlite. Roots emerge in 1–2 weeks at room temperature. Once roots are 5 cm long, pot into aroid mix and treat as a new plant. A single stem cutting can include 2–3 nodes and produce multiple new plants.

Self-heading philodendrons are slower and trickier to propagate. P. gloriosum can be propagated by cutting the rhizome into sections, each with at least one mature leaf and a root — let the cut surface dry for a day, then pot into aroid mix kept barely moist until new growth appears (4–8 weeks). Stem cuttings from P. bipinnatifidum root in water but take 2–3 months to develop enough roots to pot up. Spring and early summer are the best seasons for all philodendron propagation.
