English ivy (Hedera helix) is a perennial vine most commonly used as a ground cover in rock gardens or for covering walls, fences and trellises as a quick climbing vine. A fairly cold hardy plant that grows well into zone 5, English ivy will need only a little extra care to survive through the winter months.
Things You'll Need
- Anti-transpirant spray
Water well in late fall before the first frost or before the ground freezes. Use a drip irrigation to avoid getting the foliage wet. Thoroughly soak the soil in mid- to late fall, providing extra water for the ivy to use during the winter months when the ground is frozen making it hard for the roots to absorb enough moisture.
Apply a 2 to 3-inch layer of mulch in late fall before the first frost or once temperatures drop toe 40 degrees Fahrenheit or lower during the night. Use chopped leaves or wood chips to provide the best insulation for the roots during the cold months.
Reduce the risk of over-exposure to full sun or windy conditions by placing burlap over the plants. Being exposed to these conditions can cause the foliage to become burned and make the plant more susceptible to not surviving the winter.
Spray the ivy with an anti-transpirant spray in late fall to protect the foliage from drying winds and the frozen ground. These conditions can deprive the plant of it's natural moisture intake and when using this spray, moisture loss is reduced by up to 80 percent. Spray when temperatures are no lower than 40 degrees Fahrenheit and before the ground freezes. Use a 1:5 ratio, 1 part spray to 5 parts of water.
