Fill the new pot with 2 inches of potting soil. Use a pot with bottom drainage holes that is one size larger than the previous pot. If replanting garden ivy indoors, use a 6-inch diameter pot.
Lift the ivy out of its old pot. Dig around the roots of garden ivy to loosen the soil, then lift the entire plant out of the bed.
Set the ivy plant in the new pot. Add more soil beneath the roots, as needed, until the crown of the ivy plant sits 1 inch beneath the rim of the pot. The crown is the base of the plant, where the upper stems emerge from the root system.
Fill the remainder of the pot around the ivy roots with potting soil. Fill the pot to within an inch of the rim but do not cover the crown of the ivy with soil.
Water the soil until moisture begins dripping out of the bottom holes in the pot. Add more soil if watering caused the soil to compact and the soil level dropped.
