🌱 Philodendron Black Cardinal

Use a loose, fast-draining aroid mix (potting soil cut heavily with perlite plus chunky bark and/or sphagnum/coconut fiber). Keep the medium evenly moist but never waterlogged; ensure a pot with drainage and avoid compacted fine peat-only mixes.

This cultivar is not usually grown from seed (seed is uncommon indoors and seedlings will not come true to type). Propagate by division of basal offsets or by stem sections with at least one node, potted into a well-aerated aroid mix. Root warm (about 20–27°C), keep evenly moist (not waterlogged), and provide bright, indirect light. Repot or pot-on when roots fill the container, typically in spring or early summer.

Feed during active growth (spring–summer) with a balanced liquid fertilizer at 1/4–1/2 strength every 4–6 weeks, or use a light rate of slow-release granular fertilizer. Reduce or stop feeding in winter; flush the pot occasionally to limit salt buildup.

Optional: apply a thin top-dressing of bark or clay pellets to reduce surface evaporation and splashing; keep mulch from touching the stem/crown to reduce rot risk and remove if fungus gnats increase.

A self-heading (non-climbing) philodendron; it typically does not require staking. If grown in low light or becomes top-heavy, use a short bamboo cane or ring stake to keep the crown upright and prevent the pot from tipping.

Prune by removing yellowing/damaged leaves at the base with clean tools. To control size or refresh a leggy plant, take stem cuttings (each with a node) and root in a potting medium; avoid removing more than about one-third of the foliage at once.
