Philodendron Care Guide — Heartleaf vs Split-Leaf Basics
Indoor plant
Philodendron covers trailing heartleaf vines and larger upright/split types. Care overlaps heavily with pothos: drainage, bright indirect light, and respect for calcium oxalate.
- Aroid
- Trailing or upright
- Toxic to pets
- Bright indirect
Quick facts
| Common types | Heartleaf (P. hederaceum); selloum / tree types; many hybrids |
|---|---|
| Light | Bright indirect; avoid harsh midday scorch |
| Water | When top ⅓ is dry |
| Soil | Chunky aroid mix |
| Humidity | 40%+ preferred for larger leaves |
| Toxicity | Calcium oxalate — toxic if chewed |
| Growth | Vine or self-heading depending on species |
| Difficulty | Beginner (heartleaf) to intermediate (large hybrids) |
Overview
Care steps
-
Step 1
Chunky mix + hole in the pot
Bark + perlite + coco. Cachepots are sleeves only.
-
Step 2
Water when the top third dries
Thorough soak, dump saucer. Winter = less frequent.
-
Step 3
Bright indirect; moss pole optional
Heartleaf trails or climbs. Larger types appreciate a stake/pole and stable light.
-
Step 4
Propagate node cuttings
Like pothos: node in water or moss, then pot up.
-
Step 5
Keep away from chewers
Toxic. Hang trailing vines.
Common problems
Yellow leaves from the base
Why: Overwater or low light.
Fix: Airier mix; more light. See yellow-leaf guide.
Leggy vines with tiny leaves
Why: Not enough light.
Fix: Move brighter; prune and re-root tips.
Brown crispy edges
Why: Dry air, salts, or underwatering.
Fix: Even moisture; flush salts; modest humidity.
Mealybugs in axils
Why: Common on soft new growth.
Fix: Isolate; alcohol swab; repeat treatment.
Companions & placement
- With pothos: same shelf and mix — pothos care.
- With calathea: calathea wants higher humidity and more even moisture — calathea care.
- Avoid: calling every split leaf a “philodendron” without checking the tag — care still starts with light + drainage.

FAQ
Philodendron vs pothos?
Both beginner aroids. Pothos leaves are usually thicker with a distinct petiole ridge; care is nearly identical.
How often to water philodendron?
When the top third of the mix is dry. Don’t water on a fixed weekday.
Is philodendron toxic to cats?
Yes. Calcium oxalate causes oral irritation and vomiting.
Do philodendrons need a moss pole?
Heartleaf can trail. Larger climbers look better and leaf-out bigger on a pole.
Why are philodendron leaves small?
Low light or a tight, wet pot. Increase light and refresh mix.
Can I grow philodendron in water forever?
It can survive; pot into chunky mix for a fuller plant.
