Philodendron Care Guide (Indoor and Outdoor Growing Tips)

Philodendrons are a large group of tropical plants grown mainly for their foliage. Most types are grown as indoor plants because they tolerate household conditions, recover quickly from minor mistakes, and respond strongly to light, watering consistency, and nutrition.

This guide covers philodendron care for the most common indoor and landscape types, including Heartleaf (Philodendron hederaceum), Philodendron Birkin, Pink Princess, and the self-heading landscape forms often sold as Xanadu or Hope.

Philodendron Care Summary (Best Conditions)

Light: bright, indirect light for best growth; many types tolerate medium light
Water: water when the top layer of soil is drying; avoid constantly wet soil
Soil: airy, free-draining mix that holds some moisture but does not stay soggy
Humidity: moderate humidity helps leaf size and unfurling, but most adapt to indoor air
Temperature: stable warmth; protect from cold drafts and sudden drops

Recommended Fertiliser for Philodendrons (Indoor)

For indoor philodendron plants, the most reliable approach is consistent, gentle feeding using an indoor-specific fertiliser designed for foliage growth.

CompleteGrow Indoor Plant Food Fertiliser
- NPK ratio: 16-4-14
- Best for: philodendrons grown in pots indoors (foliage-focused growth)
- Why it works: supports stronger leaf colour, steady new growth, and healthier root systems without pushing weak, stretched stems
- Feeding style: low strength, consistent schedule during active growth

How Much Light Do Philodendrons Need?

Most philodendrons grow best in bright, indirect light. In lower light, plants often survive but grow slower, produce smaller leaves, and develop longer gaps between leaves. Variegated types (such as Birkin and Pink Princess) need brighter indirect light than solid green types to maintain pattern and colour.

Best: bright, indirect light near a window with filtered sun
Okay: medium light (slower growth, smaller leaves)
Avoid: harsh direct sun on leaves (can scorch)

How Often to Water Philodendron Plants

The most common reason philodendrons decline is watering extremes. They prefer evenly moist soil that still drains freely. Water when the top few centimetres of mix are drying, then water thoroughly so excess drains out.

Typical indoor schedule: every 7–10 days (varies by season, light, pot size)
In winter: reduce frequency if growth slows and soil dries more slowly
Warning sign of overwatering: soil stays wet for long periods, yellow leaves, soft stems

Best Soil for Philodendrons

Philodendrons are aroids and prefer a mix that is airy and fast-draining but still holds moisture around roots. Dense mixes keep roots wet for too long, which causes slow growth and leaf yellowing.

Use a well-draining indoor mix as a base
Increase aeration with chunky material (to avoid waterlogging)
Choose pots with drainage holes

When to Repot Philodendron

Repot when roots circle the pot, growth slows despite correct care, or the mix no longer drains well. Many indoor philodendrons benefit from repotting every 12–24 months depending on growth rate and pot size.

Can a Philodendron Grow in Water?

Yes. Philodendrons can root and live in water, especially Heartleaf types. However, long-term growth is usually slower unless nutrients are supplied. The best long-term results generally occur in a well-draining soil mix.

How to Propagate Philodendron

Most vining philodendrons propagate easily from cuttings. Cut below a node, then place the cutting in water or into moist propagation mix. Roots typically form in a few weeks in warm conditions with bright indirect light.

Philodendron Birkin Care

Philodendron Birkin is a compact, self-heading type valued for its striped foliage. It grows best with stable light and consistent watering. Brighter indirect light improves striping and keeps growth compact.

Light: bright, indirect light to maintain strong variegation
Water: allow the top layer to dry slightly between watering
Common issue: reverting leaves (more green) in low light

Pink Princess Philodendron Care

Pink Princess needs brighter indirect light than most philodendrons to maintain pink variegation. In low light it often produces darker, less variegated leaves. Keep care consistent and avoid extremes, as stressed plants lose quality foliage.

Light: bright, indirect light for colour retention
Water: consistent moisture without waterlogging
Growth note: slower than green philodendrons, especially indoors

Heartleaf Philodendron (Philodendron hederaceum) Care

Heartleaf philodendron is one of the easiest indoor philodendrons. It tolerates medium and even lower light, but grows faster and fuller with brighter indirect light and regular pruning.

Best for beginners: highly adaptable indoors
Keep it bushy: prune and replant cuttings into the pot
In water: roots readily in water and can grow there short to medium term

Philodendron Xanadu / Hope (Outdoor and Indoor)

Xanadu and Hope types are self-heading, non-vining philodendrons often grown outdoors in warm climates or as large indoor statement plants. Outdoors, they prefer bright shade or filtered sun and well-draining soil.

Outdoor light: bright shade / filtered sun (avoid harsh midday sun)
Watering: consistent moisture until established, then moderate watering
Cold sensitivity: protect from cold snaps and frost

Are Philodendron Plants Poisonous to Cats and Dogs?

Yes. Philodendrons contain calcium oxalate crystals and are considered toxic if chewed or ingested. Keep out of reach of pets and children and wash hands after pruning if you have sensitive skin.

Frequently Asked Questions

How do you care for a philodendron plant?

Give bright indirect light, water when the top layer is drying, use free-draining soil, and feed gently during active growth for steady foliage production.

Can a philodendron grow in water?

Yes. Many philodendrons root easily in water, but long-term growth is usually better in a well-draining potting mix unless nutrients are supplied.

Are philodendrons easy to care for indoors?

Yes. Most philodendrons are low-maintenance indoor plants and tolerate typical household conditions, especially Heartleaf types.

Is a philodendron the same as a pothos?

They are different plants but look similar. Philodendrons usually have thinner, more heart-shaped leaves, while pothos leaves are thicker and often more waxy.

For indoor philodendrons, consistent nutrition supports stronger foliage and steadier growth. A purpose-formulated indoor plant fertiliser is the most reliable way to prevent slow growth and pale leaves in pots.
