Care Essentials
Get to Know Your Philodendron Cordatum
The #1 killer? Overwatering. Let the soil dry between waterings and your Philodendron Cordatum will thrive.
Light
medium to bright indirect
Most comfortable in medium to bright indirect light. Avoid prolonged direct sun exposure.
💡 Grow lights: Thrives under artificial grow lights (LED or fluorescent, 10-12 hours/day). A great option if your space lacks natural light.
Watering
every 10-14 days
Let the soil dry out significantly between waterings — this plant is very sensitive to overwatering. When in doubt, wait another day.
Humidity & Temperature
Not fussy about humidity. Handles average indoor conditions without issue.
Standard room temperature (60-80°F / 15-27°C) is perfect. Avoid cold drafts and sudden temperature swings.
Soil
Standard well-draining potting mix works well. Add perlite for extra drainage if you tend to overwater.

Why are my Philodendron Cordatum leaves turning yellow?
Yellow leaves on heartleaf philodendron (Philodendron cordatum / Philodendron hederaceum) develop when the soil is kept too wet for too long, because persistently saturated substrate starves roots of oxygen and forces the plant to shed its older foliage

Why are my Philodendron Cordatum leaves turning yellow?
Yellow leaves on heartleaf philodendron (Philodendron cordatum / Philodendron hederaceum) develop when the soil is kept too wet for too long, because persistently saturated substrate starves roots of oxygen and forces the plant to shed its older foliage
Cause
Yellow leaves on heartleaf philodendron (Philodendron cordatum / Philodendron hederaceum) develop when the soil is kept too wet for too long, because persistently saturated substrate starves roots of oxygen and forces the plant to shed its older foliage. The houseplant reference explicitly names yellow leaves as the diagnostic sign of overwatering for this species.
Solutions
- Stop watering and allow the surface of the soil to dry out between waterings, especially during winter when growth slows.
- Check that the pot has drainage holes and that the mix is 50 percent regular potting soil mixed with 50 percent coco coir so excess water can escape.
- Move the plant to medium indirect light and never direct sunlight, which would otherwise scorch already-stressed foliage.
- Trim yellow leaves at the petiole base once the plant has stabilised, so energy is redirected to healthy new growth.
Prevention
Keep the soil lightly moist from spring until autumn, allow the surface to dry between waterings in winter, use a well-draining mix of 50 percent regular potting soil with 50 percent coco coir, and confirm the container has unobstructed drainage holes so the roots never sit in standing water.
Diseases (1 topics · 1 cases)
Why does my Philodendron Cordatum have root rot?
Root rot in heartleaf philodendron (Philodendron cordatum / Philodendron hederaceum) is triggered when the substrate stays waterlogged, because the fine epiphytic roots suffocate and decay in oxygen-poor, saturated media

Why does my Philodendron Cordatum have root rot?
Root rot in heartleaf philodendron (Philodendron cordatum / Philodendron hederaceum) is triggered when the substrate stays waterlogged, because the fine epiphytic roots suffocate and decay in oxygen-poor, saturated media
Cause
Root rot in heartleaf philodendron (Philodendron cordatum / Philodendron hederaceum) is triggered when the substrate stays waterlogged, because the fine epiphytic roots suffocate and decay in oxygen-poor, saturated media. General houseplant guidance and the genus symptom checklist both name root rot as a primary problem of philodendrons kept in poorly drained or overwatered containers.
Solutions
- Lift the plant from its pot and inspect the roots: cut away any black, mushy or sour-smelling tissue with sterilised scissors, leaving only firm white or cream roots.
- Re-pot into a fresh, well-draining mix of 50 percent regular potting soil combined with 50 percent coco coir in a container that has working drainage holes.
- Adjust the watering rhythm so the surface of the soil dries out between waterings, especially during the cooler winter months.
- After recovery, position the plant in medium indirect light and avoid direct sunlight that would compound heat and moisture stress on the recovering root system.
Prevention
Use a welldraining 50/50 mix of potting soil and coco coir in a container with unobstructed drainage holes, water only when the soil surface begins to dry, never let the pot sit in standing water, and keep the plant in medium indirect light so the substrate dries predictably.
Pests (1 topics · 1 cases)
What pests are on my Philodendron Cordatum?
Pests on heartleaf philodendron (Philodendron cordatum / Philodendron hederaceum) are opportunistic sap-suckers such as aphids, scale insects, spider mites, and mealybugs, which settle on the foliage and stems of this tropical evergreen when indoor air is dry or when a new plant is introduced without quarantine

Cause

Solutions
- Wash down all of the leaves and stems with a gentle stream of water to physically dislodge aphids, scale insects, spider mites, and mealybugs from the foliage.
- After rinsing, spray the plant thoroughly, including under the leaves, with an organic neem oil solution to eradicate any remaining pests and their eggs.
- Quarantine the affected plant away from other houseplants during treatment so the infestation cannot spread to nearby specimens.
Prevention
Inspect new heartleaf philodendrons before purchase and isolate them during acclimation, wipe the foliage periodically with tepid water to remove early settlers, keep the plant in medium indirect light with reasonable humidity, and treat at the first sign of aphids, scale insects, spider mites, or mealybugs with a wash-down plus organic neem oil spray.
