Irish Ivy (Hedera hibernica) belongs to the Araliaceae family and is a easy houseplant to look after. This fast grower plant is happiest in medium to bright and reaches 60–300 cm indoors.
For watering, the rule is simple: let the top dry out. In the growing season it needs water roughly every 6 days, dropping to every 10 days in winter. Use the watering calculator below to tune that rhythm to your pot size, light and household humidity.
Important: Irish Ivy is toxic to pets — keep it out of reach of cats, dogs and children.

Let the top 2–3 cm dry and finger-check before watering again.
Irish Ivy prefers medium to bright but will cope with medium, indirect. Harsh midday sun can scorch sensitive leaves, while too little light leads to leggy, sparse growth.
Keep Irish Ivy between 10–24 °C and aim for around 55% humidity (40% minimum). Below 2 °C it risks cold damage — keep it away from draughty windows and radiators.

Soil between waterings
Pot Irish Ivy in free-draining, loam-based mix. A drainage hole is essential — soggy, airless soil is the single most common way houseplants die.
English ivy is toxic to cats and dogs (vomiting, drooling) and its sap can cause contact dermatitis in people — wash hands after pruning.
The best ways to propagate Irish Ivy are stem cuttings, water-rooting nodes and layering. Late spring and summer are ideal, when the plant is growing most actively.
Indoor ivy is prone to spider mites in dry heat — a monthly shower under the tap knocks them back better than any spray.
In the growing season Irish Ivy needs watering about weekly (about every 6 days in a 16 cm pot at medium light), and much less in winter — roughly every 10 days. Use the watering calculator above to get the exact interval for your conditions.
Irish Ivy thrives in medium to bright. A spot near a bright window out of harsh midday sun is ideal; give it a little more light in winter.
