Philodendron mayoi

Philodendron mayoi

Philodendron mayoi is a Brazilian species in the Araceae family, known for glossy green leaves that become more deeply divided as the plant matures. Juvenile leaves are simpler, while older blades develop a cut, fingered outline with divisions reaching toward the midrib.

This Philodendron is best described as a scrambling to scandent species rather than a strict upright climber. In a pot, the stems may spread outward from the base or be guided gently onto a small support, with mature foliage becoming more sharply divided than the first juvenile leaves.

Divided leaves and scandent Philodendron mayoi stems

• Foliage: Glossy green leaves with a divided outline.
• Juvenile growth: Young leaves are less divided and become more cut with maturity.
• Growth habit: Scrambling to scandent growth, with stems that can spread or be guided upward.
• Origin: Brazilian species from Brasília D.F. and Goiás.
• Habitat context: Brazilian seasonally dry tropical conditions, with care that favours air around the roots and steady warmth.
• Safety: Toxic if chewed or swallowed by pets or children.

Juvenile and mature leaf shape in Philodendron mayoi

Young Philodendron mayoi plants can produce simpler blades before the more divided mature foliage appears. As the plant gains size, the cuts become more pronounced and the leaf outline develops a sharper, more fingered shape.

The stems extend outward or upward depending on how the plant is grown. A small support can guide scandent growth, while a wider pot gives spreading stems room to develop without crowding the newest leaves.

Care for Philodendron mayoi in a pot

• Light: Give Philodendron mayoi bright filtered light. Weak light can produce stretched growth and smaller, less clearly divided leaves.
• Water: Water when part of the potting mix has dried, then let the pot drain fully. Long wet periods around spreading stems can stress the roots.
• Substrate: Use a loose aroid mix that drains quickly while holding light, even moisture.
• Humidity: Moderate to higher humidity helps new divided leaves expand without dry edges.
• Temperature: Keep warm and stable, ideally above 18 °C, with protection from cold draughts and cold wet substrate.
• Support: Use a small pole, plank or stake if you want to guide scandent stems upward.
• Pot choice: Choose a stable pot with enough surface space for the spreading stem base and free drainage below.
• Repotting: Repot when roots fill the pot, the substrate breaks down, or spreading stems need more stable space at the surface.
• Fertilising: Feed lightly during active growth with a balanced houseplant fertiliser at diluted strength.
• Growth rate: Growth is usually moderate indoors, with clearer leaf division developing as the plant gains size.

Philodendron mayoi pruning, propagation and mineral substrates

• Pruning: Remove damaged leaves close to the petiole base, or trim an overextended stem above a node.
• Propagation: Propagate from stem cuttings with at least one node and healthy aerial-root tissue.
• Semi-hydro: Suitable for mineral or semi-hydro substrates if the roots stay warm, oxygenated and not stagnant.
• Training: Guide flexible stems early if you want a more upright plant shape.

Philodendron mayoi leaf division, dry edges and root stress

• Less divided leaves: Juvenile leaves are naturally simpler, but weak light can also reduce leaf size and definition.
• Yellowing leaves: Check for wet roots or a dense potting mix that stays damp too long.
• Crispy margins: Dry air, underwatering or heat stress can mark the thin edges of divided leaves.
• Root issues: Slow growth with yellowing leaves often points to compacted substrate, poor drainage or cold wet roots.
• Pests: Inspect the cuts, leaf backs and new growth for thrips, spider mites, mealybugs and scale.

Philodendron mayoi toxicity

Philodendron mayoi contains insoluble calcium oxalate crystals. Keep the plant out of reach of pets and children that may chew leaves, petioles or stems.

Philodendron mayoi name origin and botanical background

Heinrich Wilhelm Schott described the genus Philodendron in 1829 in Wiener Zeitschrift für Kunst, Litteratur, Theater und Mode; its name combines Greek philo- or philein, meaning loving, and dendron, meaning tree. Philodendron mayoi was described by Eduardo G. Gonçalves and published in Kew Bulletin in 2000. The species epithet mayoi honours the aroid botanist Simon J. Mayo.

With glossy divided leaves and spreading scandent growth, Philodendron mayoi develops a distinctive mature outline in an indoor aroid collection.
