Light: Bright, indirect light. Some morning sun is fine. Plants that don't get enough light will have leggy stems with wide gaps between leaves. Move your ivy to a brighter spot, but keep it out of harsh, direct sunlight.

Water: Keep soil moist spring through fall when plant is actively growing. Water sparingly in winter.

Humidity: Moderate humidity. This plant loves to be misted with room-temperature water. 

Temperature: Average room temperatures (60-75°F/16-24°C) year-round. This tropical plant doesn't like the cold, so keep it at a minimum of 60°F/16°C. 

Soil: Peat moss-based potting mix.

Fertilizer: Feed monthly spring through fall with a balanced liquid fertilizer diluted by half. Do not feed in winter.
Propagation: Take stem cuttings in spring or summer. They'll root easily in water or moist potting mix.
