One of the most popularly grown ivies is the English ivy (Hedera helix), which is a climbing vine with attractive lobed leaves. English ivies have a wide range of landscape uses, trained to grow on walls, arbors, trellises, fences and railings. English ivies are also grown as trailing groundcovers in landscaping beds. English ivy plants can tolerate winter temperatures as cold as -20 degrees F, depending on the cultivated variety, and are generally more sensitive to heat stress and waterlogged soils than any other problems.
Water your newly planted English ivy beds once or twice a week to provide 1 inch of water each week. Water established English ivy plants about once a week during times of drought or prolonged dry spells and in late fall before the first hard freeze.
Feed your English ivies with 1 pound of a slow-release 12-4-8 or 15-5-15 NPK fertilizer per 1,200 square feet of bed in spring and again in early fall. Provide a third fertilizer application in summer during the first year after planting the ivies.
Spread a 2- to 4-inch thick layer of organic mulch onto the soil in the bed around the English ivy plants after first planting them. The mulch will control weed growth, keep the soil cooler and retain soil moisture during the first year or two while the English ivies are growing to create a tight bed.
Prune your English ivies while they're actively growing to keep them inside the bounds of the bed and to encourage healthy growth. Clip back the ivy vines and cut away upper layers of vines that are crowding lower layers. You can also pinch back the tips of vines in bare spots to train them to grow in the desired areas.
