Philodendron Care: Light, Water, Pots and Climbing

Give a philodendron bright indirect light, water when the top inch of the mix is dry, keep it warm, and let it climb or trail. Patch Plants sums up the routine as bright, indirect light, a thorough watering once the top inch has dried, temperatures between 18 and 29 C (never below 10 C), and a balanced feed through spring and summer. NC State Extension rates the heartleaf philodendron, Philodendron hederaceum, low maintenance and fast growing, and says it tolerates deep shade and can survive long periods in very low light.

The short routine:

• Light: a few feet from an east or west window, or behind a sheer curtain in a south one.
• Water: only when the top inch is dry; water until it drains, then empty the saucer.
• Warmth: 65 to 85 F, away from cold drafts.
• Food: balanced fertiliser in the growing season, nothing in winter.
• Support: a moss pole for climbers, a shelf edge for trailers.

Every part of the plant is toxic to cats and dogs; see our philodendron pet page.

Care is almost the same across the genus, but the support is not. Orange Lake Nursery sorts common varieties into three habits:

• Vining or climbing: Micans, Silver Stripe, Melanochrysum, and the heartleaf philodendron, whose stems NC State says reach 4 feet or more on aerial roots. These want a moss pole or a place to trail.
• Self-heading or upright: Birkin, Moonlight, Prince of Orange. They grow from a central crown and need neither pole nor hanging pot. The large split-leaf philodendron, which NC State lists as Philodendron bipinnatifidum (now Thaumatophyllum bipinnatifidum), is an upright woody shrub 4 to 10 feet tall and 6 to 10 feet wide.
• Crawling: Gloriosum, which creeps along the soil surface and needs a wide, shallow pot rather than a pole.

If you do not know which you have, a photo of the whole plant and a leaf will tell you; see house plant identification.

Light, yes; direct sun, mostly no. Patch Plants says philodendrons prefer bright, indirect light and tolerate low light without thriving in it, and suggests east- or west-facing windows. Orange Lake Nursery prefers north or east windows, sheer curtains on south and west ones, and 10 to 12 hours a day under LED grow lights if a room is dark. NC State lists the heartleaf philodendron as tolerant of deep shade, under two hours of direct sun a day, and the split-leaf as preferring high light but getting leaf scorch in full sun.

Nouveau Raw's rule for pothos, a close look-alike, applies here too: long gaps between new leaves mean too little light. Move it closer to the window before you change anything else.

Water by the soil, not the calendar. Patch Plants says to water when the top inch is dry, water thoroughly until it runs out of the drainage holes, then let it dry again; Orange Lake Nursery says the top one to two inches; NC State says keep the heartleaf slightly moist and water less in winter. All three agree that soggy soil is the thing to avoid.

For mix, Orange Lake Nursery's recipe is 40% peat or coco-based potting soil, 30% perlite or pumice, 20% orchid bark or coco chips and 10% worm castings or compost. NC State notes the split-leaf philodendron is sensitive to salt build-up and suggests flushing the pot regularly or using distilled water.

Should you mist a philodendron? NC State says the heartleaf appreciates misting but tolerates dry air. Penn State Extension (Lois Miklas, updated 13 December 2024) explains why misting does little: the rise in humidity lasts only until the water evaporates, which can take minutes, and a pebble tray's moisture diffuses into the whole room. Grouping plants, a humidifier or a cloche actually raise the humidity around the leaves. Mist if you enjoy it; do not rely on it for velvet-leaf varieties, which Orange Lake Nursery says want 60 to 70% humidity.

A pot only slightly bigger than the root ball, stepped up gradually. Patch Plants says to repot when roots are crowded and start poking out of the bottom, into a pot only slightly larger than the last; Orange Lake Nursery says 1 to 2 inches wider, usually about once a year, in spring or early summer. A much bigger pot holds wet soil around a small root system, which is how overwatering happens even when you water correctly. Always use a pot with drainage holes. Crawling types such as Gloriosum want width rather than depth.

Vining philodendrons do both; climbing gives bigger leaves. In the wild they are fast-growing climbers, and Patch Plants notes they are commonly grown up a moss pole at home. NC State describes the heartleaf's aerial roots reaching 4 feet or more, which grip a pole if you give them one. Hanging is fine if you like long trails; pinch or cut the ends to keep the top full. Self-heading types such as Birkin do not climb or trail, so give them neither.

The two nursery sources differ on feeding: Patch Plants feeds a balanced fertiliser every two weeks in spring and summer, while Orange Lake Nursery feeds every four to six weeks with a balanced 20-20-20 or a diluted 10-10-10, from spring to early autumn, and skips winter unless the plant is under grow lights. Start at the less frequent end; white crust on the soil means you are overdoing it.

Prune dead or damaged leaves and trim stems that have grown too long (Patch Plants). Every cut stem with a node can become a new plant: Orange Lake Nursery roots cuttings in water, sphagnum moss or soil, sees roots in two to four weeks, and pots them up once roots are 1 to 2 inches long. NC State lists stem cuttings as the method for heartleaf philodendron.

• Brown leaf edges. Low humidity (Orange Lake Nursery). Group plants or use a humidifier.
• Yellow leaves in a mix that stays wet. Likely root rot; NC State lists root rot for both heartleaf and split-leaf. Let the mix dry further and check the pot drains.
• Small leaves with long gaps. Too little light.
• Scorched patches. Direct sun; NC State records leaf scorch on the split-leaf in full sun.
• Pests. NC State lists aphids, spider mites, mealybugs and scale, plus banded greenhouse thrips on the split-leaf; Orange Lake Nursery adds fungus gnats from overwatering and treats with neem oil, insecticidal soap or rubbing alcohol. See spotting and treating plant pests.
• Leaves that look like a pothos. You may have a pothos. NC State's test: philodendron leaf stalks are not grooved, and new growth has conspicuous sheaths (stipules). Our pothos care guide covers the other plant.

A bright room out of direct sun, out of reach of pets, and away from drafts. Patch Plants suggests bathrooms and kitchens because they are naturally more humid, as long as there is a window. Keep it above 55 F (Orange Lake Nursery) and off cold windowsills in winter. In a home with cats or dogs, a high shelf or hanging pot is the practical choice, because NC State lists all parts as containing calcium oxalate crystals and warns the sap can cause contact dermatitis.

NC State rates heartleaf philodendron a low-severity poison for people, cats and dogs, with oral irritation, pain and swelling of the mouth, tongue and lips, excessive drooling, vomiting and difficulty swallowing as the signs; the split-leaf carries the same warning. If a pet may have eaten a toxic plant, call your veterinarian, the ASPCA Animal Poison Control Center on (888) 426-4435 or Pet Poison Helpline on (855) 764-7661. For a person, call Poison Control on 1-800-222-1222 (US). Our philodendron pet page has the ASPCA listing.
