SpecieAnthurium pedatoradiatum

Anthurium pedatoradiatum is a tropical aroid in the family Araceae, grown for its colourful spathes or boldly veined foliage; sap is irritant.

Guida alla cura
Luce

Bright indirect light is essential for Anthurium to produce its distinctive waxy spathes (the colourful 'flower' — actually a modified leaf). An east-facing window or a bright spot behind a sheer curtain is ideal. Direct sun scorches the waxy bracts and leaves. In lower light, Anthurium survives but produces few or no flowers.

Acqua

Allow the top 2–3 cm of soil to dry between waterings, then water thoroughly. Anthurium prefers consistently moderate moisture but is very susceptible to root rot if overwatered. Yellow leaves usually indicate overwatering; drooping with dry soil indicates underwatering. Use room-temperature water and ensure excellent drainage.

Substrato

Chunky, well-draining mix: 40% orchid bark, 30% perlite, 30% potting compost. Anthurium is semi-epiphytic — its roots need excellent aeration. Avoid dense, water-retentive soils.

Temperatura e umidità

Optimal 18–27 °C; minimum 15 °C. High humidity (60–80%) significantly extends flowering and promotes larger, more vivid spathes. Use a humidifier or pebble tray. Avoid cold drafts which cause spathe browning.

Concimazione

Feed every 2–4 weeks during spring and summer with a fertilizer higher in phosphorus (the P in NPK) to promote flowering. A balanced fertilizer at half strength works well. Stop feeding in winter.

Potatura

Remove spent spathes (flowers) at the base once they turn green and then brown. This encourages the plant to produce new blooms. Wipe the waxy leaves with a damp cloth to remove dust. Repot every 2 years in spring. Anthurium contains calcium oxalate — toxic to pets and humans if ingested.

Propagazione
Divisione

The most common method for propagating Anthurium is by division. This involves separating the root ball during repotting. Ensure the parent plant is healthy before proceeding.

1
Carefully remove the plant from its pot and gently shake off excess soil to expose the roots.
2
Locate natural divisions in the root ball where new shoots are emerging.
3
Use a sharp, sterilized knife to cut the roots, ensuring each division has at least one shoot and some roots.
4
Plant each division in a separate pot with a well-draining potting mix, water thoroughly, and place in bright, indirect light.
Talea

Some Anthurium species can be propagated from stem cuttings.

1
Cut a healthy stem from the parent plant just below a node.
2
Allow the cut end to dry and form a callus for a few hours.
3
Place the cutting in a container with moist, well-draining potting mix.
4
Keep in a warm, humid environment with indirect light until roots develop.
