Philodendrons are the plants that turn a nervous beginner into someone with opinions about aroid soil. They grow fast enough that you can see your care working, they forgive a missed watering, and there’s a philodendron for basically every corner of a home — trailing off a bookshelf, climbing a pole in a bright hallway, or filling a whole window with leaves the size of dinner plates.
There are hundreds of species, but the good news is they nearly all want the same handful of things. Learn those once and you can grow any of them.
Meet the Philodendron
Philodendrons are tropical aroids, mostly native to the rainforests of Central and South America. In the wild, many of them germinate on the forest floor and then climb — hauling themselves up tree trunks with aerial roots, reaching for brighter light as they go. That single fact explains most of their care: they want dappled light, chunky airy footing for their roots, and something to climb.
They split into two broad habits, and it’s worth knowing which one you’re bringing home:
- Vining / climbing types — Heartleaf (P. hederaceum), Brasil, Micans with its velvety bronze leaves, Lemon Lime, Pink Princess, Philodendron gloriosum (which creeps sideways rather than up). These trail or climb and love a support.
- Self-heading types — Philodendron selloum / Hope, Xanadu, Birkin, Prince of Orange, Moonlight. These grow outward from a central crown into a shrubby shape and never need a pole.
A quick note on names: the Split-Leaf Philodendron sold at most garden centers is usually a Monstera deliciosa, which is a different genus entirely. Care overlaps a lot, but don’t be surprised when your “philodendron” starts putting holes in its leaves.
Light
Bright, indirect light is the sweet spot. Think a few feet back from an east or north window, or right up against a sheer-curtained south or west one.
- Ideal: bright indirect light for most of the day.
- Tolerates: medium light — growth slows and new leaves come in smaller.
- Avoid: hours of unfiltered direct sun, which scorches pale patches into the leaves.
Variegated cultivars need noticeably more light than plain green ones. A Pink Princess or a Birkin kept too dim will start pushing out solid green leaves because the plant can’t afford the non-photosynthesizing white and pink tissue. If your brightest window still isn’t enough, a full spectrum LED grow light on a timer holds the variegation steady through winter.
Leggy stems with long bare gaps between leaves are the other tell. That’s the plant stretching for light, not a watering problem.
Water
Philodendrons like their soil to dry out partway between drinks — not bone dry like a snake plant, not constantly damp either.
- Water thoroughly when the top 1–2 inches feel dry to the touch.
- Let water run out the drainage hole, then empty the saucer. Never leave the pot standing in water.
- Roughly every 7–10 days in spring and summer; stretch it out in winter when growth slows.
Skip the calendar and check the soil instead — a pot by a heat vent dries in half the time as one in a cool bedroom. If you’d rather have a number than a hunch, a soil moisture meter takes the argument out of it.
Yellowing lower leaves usually mean too much water. Drooping stems with dry, crispy edges mean too little. Philodendrons are dramatic about thirst and bounce back within hours of a good soak, which makes them very satisfying to rescue.
Soil
This is where a lot of people go wrong with a bag of straight potting mix. Aroid roots need air as much as they need moisture, and dense soil suffocates them.
Use a chunky, fast-draining aroid potting mix, or build your own — it’s cheaper and better:
- 3 parts quality indoor potting soil
- 2 parts orchid bark
- 1 part perlite
- a handful of horticultural charcoal
The finished mix should feel loose enough that water pours straight through. Whatever pot you choose, it needs a drainage hole — a planter with a drainage hole and saucer is worth more to a philodendron than any fertilizer.
Fertilizer
Philodendrons are moderate feeders and grow noticeably better with regular food during the growing season.
- Feed every 2–4 weeks in spring and summer with a diluted balanced liquid houseplant fertilizer at half strength.
- Taper off in fall; stop entirely in winter unless your plant is under grow lights and actively pushing new leaves.
- Flush the pot with plain water every couple of months to rinse out salt buildup, which shows up as a white crust on the soil and brown leaf tips.
Half strength, twice as often beats full strength occasionally. Aroid roots burn easily.
Temperature & Humidity
Comfortable room conditions suit them: 65–80°F, and never below 55°F. Keep them off cold windowsills in winter and away from heating vents and drafty doors, both of which dry leaves out fast.
Humidity is the one place your home probably falls short of a rainforest. Average household humidity is fine for common types like Heartleaf and Brasil, but the velvet-leafed ones — Micans, gloriosum, verrucosum — get visibly better leaves above 60%. Grouping plants together helps a little; a small cool mist humidifier helps a lot. Misting looks lovely and does almost nothing, so don’t rely on it.
Repotting
Repot every 1–2 years, or when you see roots poking from the drainage hole, water running straight through without soaking in, or growth stalling in the middle of summer.
- Go up one pot size only — roughly two inches wider. An oversized pot holds wet soil the roots can’t reach, and that’s how rot starts.
- Spring and early summer are the best time.
- Loosen the root ball gently, trim anything brown and mushy, and settle it into fresh mix at the same depth it was before.
Climbing types will grow dramatically bigger leaves once they have something to hold onto. Sink a moss pole into the pot at repotting time and secure the stems to it — keeping the moss damp encourages the aerial roots to grab on, and the plant responds by maturing its leaf shape.
Propagation
Vining philodendrons are almost too easy to propagate, which is why everyone’s Heartleaf came from a friend.
- Find a node — the small bump on the stem where a leaf and aerial root emerge. This is non-negotiable; a leaf with no node will never root.
- Cut about half an inch below it with clean pruning shears.
- Root it in water, damp sphagnum moss, or straight into soil. Water is slowest to transition but the most fun to watch.
- Once roots hit 2–3 inches, pot it up in your aroid mix and keep it slightly more moist than usual for the first two weeks.
Self-heading types don’t have trailing stems to cut, so they’re propagated by division at repotting — separate an offshoot with its own roots attached and pot it separately.
Common Problems
- Yellow lower leaves: nearly always overwatering. Let the mix dry further down before the next drink and check that the pot actually drains.
- Brown crispy tips and edges: dry air, inconsistent watering, or fertilizer salt buildup. Flush the soil and even out your schedule.
- Long bare stems, small new leaves: not enough light. Move it brighter and prune the leggy vines back to encourage fuller growth.
- Variegation fading to green: same cause — more light, and prune back to a variegated node.
- Fine webbing, speckled leaves: spider mites, which thrive in dry winter air. Shower the plant off, then treat with neem oil every 7 days until they’re gone.
- Sticky residue, white cottony spots: mealybugs. Dab each one with rubbing alcohol on a cotton swab, then follow with neem.
Frequently Asked Questions
Are philodendrons toxic to pets? Yes. All parts contain calcium oxalate crystals, which cause mouth irritation, drooling, and vomiting if chewed. Hang them high or choose a different plant for a home with a determined cat.
Why does my philodendron have aerial roots everywhere? That’s completely normal and healthy — it’s how a climber anchors itself. Tuck them into a moss pole, guide them back into the soil, or leave them be. Don’t cut them off unless they’re in your way.
Philodendron or pothos — how do I tell? Look at the leaf and the new growth. Philodendron leaves are thinner and softer with a heart-shaped base, and new leaves emerge from a papery sheath. Pothos leaves are thicker, waxier, and often speckled, with no sheath.
How fast should it grow? In good light through spring and summer, expect a new leaf every couple of weeks on a vining type. Winter growth slows to almost nothing, and that’s fine — don’t compensate by watering more.
