The ivy plant is a trailing foliage plant often grown as a houseplant in hanging baskets or on trellises. Prized from its bright green star-shaped leaves, ivy requires little care and grows rapidly. Although similar, English ivy and German ivy differ in foliage and stems, with the German ivy producing a woodier stem and thicker leaves. Both propagate easily from stem cuttings to produce new plants identical to the parent plant.
Take 4 to 6 inch stem cuttings from the terminal end of healthy new growth. Saving the ends when cutting the plant back is an excellent way to produce new plants in a relatively short period.
Remove leaves on the bottom 2 to 3 inches of the cutting and place in a vase of glass of water. Although it is not necessary, a clear glass is ideal as it allows you to monitor root formation without disturbing the cuttings.
Place on a windowsill that receives bright light, but avoid southern windows, as the heat from the sun may overheat the water and damage you cuttings or burn tender foliage.
Check daily and change the water often to prevent stagnation. Look for the emergence of fine hair roots. These will appear in a matter of days. Allow to grow in water for several days as roots develop, but watch them carefully. If you have several cuttings in one vase, the roots will tangle quickly, making it difficult to transplant them without damaging the roots.
Remove from the vase and transplant into moist potting soil once roots are 2 to 3 inches long and new leaves begin to form. Use care not to damage fine roots when transplanting.
