English ivy is toxic

  • Toxic to cats. Toxic principle: Triterpenoid saponins (hederagenin). Clinical signs: Vomiting, abdominal pain, hypersalivation, diarrhea. Foliage is more toxic than berries. ASPCA
  • Toxic to dogs. Toxic principle: Triterpenoid saponins (hederagenin). Clinical signs: Vomiting, abdominal pain, hypersalivation, diarrhea. Foliage is more toxic than berries. ASPCA
  • Toxic to people. Harmful when eaten; irritates skin and can cause skin allergy. Use gloves and protective gear when handling it. RHS

How it usually goes wrong

Crisp margins that appear in winter

The English ivy shows browning on many leaf blades at once, all at the margin, with no spots or soft patches anywhere.

The edges fail first because they are the end of the plumbing. Penn State Extension cites 30% to 60% as the recommended indoor range, and winter heating regularly takes a room under it. That applies while it is grown indoors; its RHS rating of H5 describes a plant that also grows outside, where the air is seldom that dry.

Telling it apart: Whether it crumbles or smears. Crisp is water lost; soft and dark is cold or rot.

Penn State ExtensionDiagnose brown tips and edges on this English ivy
Long bare stretches of stem between leaf blades

The newest leaf blades on the English ivy are the palest and smallest, and the stems carrying them bend toward the brightest side of the room.

A plant stretches when the light is short of what it evolved for. Its source describes medium light, and a room darker than that sets the vine reaching.

Telling it apart: Whether it leans. A plant reaching for a window is answering a light question, and it leans before it pales.

Clemson ExtensionDiagnose leggy growth on this English ivy
The vine yellows from below and the pot stays heavy

On a English ivy the yellowing climbs from below. Affected leaf blades feel limp rather than papery, and water sits in the saucer long after it drains through.

Roots sitting in water run out of oxygen, and the first sign above ground is the oldest leaf blades being given up. Its source describes moist but well-drained or well-drained soil, which is air as much as water.

Telling it apart: Whether the drainage hole drips when the pot is tilted. Water still running out days later is the answer.

About the plant

Hedera helix, simply ivy, or common ivy, English ivy, European ivy, King's choice ivy, is a species of flowering plant in the family Araliaceae. It is native to most of Europe and parts of western Asia. Ivy is a clinging evergreen vine that grows on tree trunks, walls, and fences in gardens, waste spaces, and wild habitats. Ivy is common as an ornamental plant, but escaped plants become naturalised outside its native range. Ivy has considerable cultural significance and symbolism.

Uses

In the past English ivy was applied to the skin for its antifungal and antimicrobial effects. Both the berries and the leaves are toxic to people.

What this does not cover

The figures above are what published sources say, not measurements of the plant in your room. They say nothing about your pot size, your water, the season, or how far from the glass the plant stands, and those decide more than any figure here does.

Humidity has no species figure because no source read for this site publishes one, and the only temperature published for this plant is a cold floor. The simulator fills those gaps with general figures for its kind of plant, marked as general and listed on how we read sources. Where a toxicity row says the plant was not assessed, that is the absence of a finding and not a finding of safety.

If something is already wrong, the diagnosis tool asks about the soil, the window and the watering, which is where the answer usually is.
