Philodendron hederaceum

Heartleaf Philodendron

Philodendron hederaceum is a tropical aroid in the family Araceae, grown as a climbing or self-heading foliage pianta di appartamento; sap is mildly toxic.

Guida alla cura

Luce

luce indiretta intensa produces the best growth for both climbing (e.g. Philodendron hederaceum) and self-heading (e.g. Philodendron gloriosum, P. bipinnatifidum) forms. Tolerates medium light but leaves become smaller and more widely spaced. Variegated cultivars (e.g. 'Brasil', 'Lemon Lime') need brighter light to maintain their colour. evitare il sole diretto.

Acqua

Allow the top 2-4 cm of soil to dry tra un'innaffiatura e l'altra, then innaffiare abbondantemente. Philodendron prefers consistent moderate moisture rather than a true dry cycle. foglie gialle on lower stems are the most common sign of overwatering; drooping with dry soil signals underwatering. Reduce frequency in winter.

Substrato

ben drenante, aerated mix: 40% potting compost, 30% perlite, 30% orchid bark. Good root aeration is important - Philodendron is epiphytic in the wild and benefits from a chunkier mix.

Temperatura e umidità

Optimal 18-27 °C; minimum 13 °C. Moderate to high humidity (50-70%) promotes larger leaves with longer internodes. umidità media dell'ambiente interno is adequate for survival, but a humidifier significantly improves growth quality.

Concimazione

Feed every 2-4 weeks during primavera e estate with a equilibrato concime liquido. Reduce to monthly in autumn, stop in winter. A fertilizer with added calcium supports large leaf development.

Potatura

Climbing Philodendrons (heartleaf, Brasil, etc.) produce larger, more mature leaves when given a moss pole or rough support to climb - direct aerial roots into the moist pole. Self-heading forms need no support but benefit from having the outer dead leaves removed regularly. All Philodendrons contain ossalato di calcio and are tossico per pets and humans if ingested.

Propagazione

Talea

The most common method for propagating Philodendron is by stem cuttings. This involves cutting a healthy stem and rooting it in water or soil.

1
Select a healthy stem with at least one node and cut it just below the node.
2
Remove any lower leaves to expose the node.
3
Place the cutting in water or directly into a pot with ben drenante soil.
4
Keep the cutting in a warm, humid environment with indirect light until roots develop.
Divisione

Some Philodendron species can also be propagated by divisione, especially those with clumping growth habits.

1
Carefully remove the plant from its pot and gently shake off excess soil to expose the roots.
2
Locate natural divisiones in the root ball where new shoots are emerging.
3
Use a sharp, sterilized knife to separate the divisiones, ensuring each section has roots and shoots.
4
Plant each divisione in a separate pot with ben drenante soil and innaffiare abbondantemente.
