How to care for an English ivy
Most ivies grow best in bright light without direct sun; they tolerate low to medium light but grow slower there, and variegated kinds turn green. Water thoroughly, then let the top half inch of soil dry before watering again, and never let the pot stand in water. Cool to moderate rooms suit it: 50 to 70°F by day and a little cooler at night. Moderate humidity is ideal, though it tolerates dry homes. Feed monthly while it's growing. When repotting, go only an inch bigger; too large a pot stays wet and rots the roots. Cuttings root easily in water. Keep it indoors: NC State lists English ivy as invasive outdoors, where it smothers native plants and is nearly impossible to remove.
Common problems
Too much or too little water causes most problems. Mealybugs, mites, aphids, whiteflies and scale; cooler temperatures and higher humidity help keep mites down. The sap gives some people a rash, so wear gloves when pruning.
