Heartleaf Philodendron: root rot — what does it look like?

Stems blackening at the base, leaves yellowing throughout, sour soil. Take cuttings from any firm green vine above the damage. The root ball is rarely worth saving.

Heartleaf Philodendron: prolonged drought — what does it look like?

Leaves curling inward, going papery, dropping. Soil hard and shrunken. Usually recoverable. Rehydrate slowly by soaking the pot rather than pouring water through.

Heartleaf Philodendron: very low light — what does it look like?

Bare stretches of vine with tiny leaves spaced far apart. Survives longer than it should in poor light, which is how it ends up too weak to recover from anything else.

What went wrong

Heartleaf Philodendron

Philodendron hederaceum

Forgiving to the point of enabling.

Heartleaf philodendron tolerates low light, irregular watering and general inattention, so when one dies it is usually because a genuinely extreme condition persisted for a long time — a pot with no drainage, months in near-total darkness, or a complete drying out that went on for weeks.

Like pothos, it roots readily from a node, which means a philodendron death is almost always partial. There is nearly always something worth cutting and saving.

Usually one of these

The question you actually have

Dead or dormant?

Find one firm node — the small bump where a leaf meets the vine. A single viable node in water will produce a whole new plant within a month. Only if every vine is dry and hollow along its entire length is it genuinely over.
