Philodendron Care Guide

Philodendron spp.

Philodendrons encompass hundreds of species ranging from compact desk plants to large climbing aroids. Most houseplant philodendrons (heartleaf, Brasil, Pink Princess) share the same basic care requirements: bright to medium indirect light, well-draining substrate, and moderate watering. They are among the most tolerant houseplants for indoor conditions.

Highly adaptable; one of the most forgiving houseplants for beginners.

Care Requirements

💡 Light

Medium to bright indirect

Adapts to medium light but grows fastest in bright indirect light. Variegated cultivars (Brasil, Pink Princess) need more light to maintain colour. Avoid direct sun on leaf surfaces.

💧 Watering

Every 7–14 days

Allow the top half of the substrate to dry between waterings. Heartleaf philodendron is highly drought-tolerant; climbing varieties prefer slightly more consistent moisture. Yellowing lower leaves indicate overwatering.

💦 Humidity

40–60%

Tolerates average household humidity well. Tropical species benefit from higher humidity but are not as sensitive as Calathea or Alocasia. Wipe leaves monthly with a damp cloth to prevent dust accumulation.

🌡️ Temperature

16–29°C

Avoid temperatures below 13°C. Keep away from cold windows and draughts in winter. Most philodendrons can handle brief temperature fluctuations but consistent warmth promotes best growth.

🌱 Substrate

Airy, well-draining mix

A mix of potting soil with added perlite (20%) provides the drainage philodendrons need. Avoid dense, compacted substrates that retain excess moisture around roots.

⚗️ Fertiliser

Every 4 weeks (spring–summer)

Feed with a balanced liquid fertiliser monthly during the growing season. Philodendrons are light feeders — over-fertilisation causes salt buildup and tip burn. Flush the substrate with plain water every 2–3 months.

Seasonal Care

Most active growth occurs March–September. Trailing varieties (heartleaf, Brasil) can grow 30–60 cm per season in good conditions. In winter, growth slows — reduce watering frequency and stop fertilising. Philodendrons don't need a cool winter rest and can be maintained at normal indoor temperatures year-round.

Repotting

Repot every 1–2 years in spring when roots fill the pot. Self-heading (non-climbing) varieties prefer a pot proportional to their leaf spread. Climbing varieties benefit from a moss pole or trellis to maximise leaf size.

Propagation

Stem cuttings are the easiest propagation method. Take a cutting below a node, allow to callous for 30 minutes, and place in water or moist perlite. Roots develop in 2–4 weeks. Philodendrons root readily at any time of year.

Philodendron FAQs

How often should I water my Philodendron?

Water when the top half of the substrate is dry — typically every 7–14 days in the growing season, less frequently in winter. Heartleaf philodendron is particularly drought-tolerant and will wilt as a visible signal before suffering serious damage.

Why are my Philodendron leaves turning yellow?

Yellow leaves most commonly indicate overwatering, particularly if multiple leaves are affected simultaneously. A single older (lower) yellow leaf is normal ageing. Check the substrate moisture and drainage before adjusting your watering routine.

Does Philodendron need high humidity?

Most common philodendron varieties tolerate average household humidity (40–50%) well. They don't require the humidity levels needed by Calathea or Alocasia. Tropical species like Philodendron gloriosum benefit from higher humidity.
