How to Control English Ivy

How do you control English ivy? It is taking over my back yard, and herbicides don’t seem to have any effect! -John

English Ivy (Hedera helix) can be very aggressive if not kept under strict control! Unfortunately, its thick, waxy leaves make it somewhat resistant to regular sprayed herbicides, so gardeners have to get creative (and more than a little dirty) in order to tackle it.

Here are some tips:

  • Unpleasant as it may be, your defense is a good ground attack. Pull as much as you can by hand, and remove or cut any stems growing up trees or structures. Pulling ivy is messy and hard work, but it goes pretty quickly.
  • As you’re pulling, don’t leave behind any little sprouts! Completely clear the ground, particularly in a large circle around trees, shrubs, and structures.
  • Remember that your ivy will grow vigorously after it’s cut – you may want to remove it all, rather than just containing it.
  • Ivy is not a parasitic plant, although it can take root as it creeps along the ground. As you pull the ivy, you need to be looking for the main stem and roots so you can remove them as well.
  • If you’re applying herbicides, be sure to choose one labeled for English ivy, or one containing the ingredient riclopyr ester.
  • You’ll have to apply herbicide repeatedly throughout the year, but particularly be sure to attack it in the early spring when new growth is emerging, as younger leaves absorb the herbicide more easily.
  • Follow the weed killer instructions exactly. Applying when temperatures are too hot or cold, applying too close to a rain, and other factors can affect the product’s strength – and with English ivy, you need everything working for you!
  • Some gardeners report success with mowing or trimming the ivy before applying weed killers. This exposes cut stems that can absorb the chemicals, and it sparks a flush of growth that results in more fluid circulation to and from the roots, which may improve the effectiveness of your weed killer.
  • Cut thicker stems with lopping shears, then paint the cut end with undiluted herbicide.
  • Make sure your weed killer includes a surfactant – if it doesn’t, you can add a couple of tablespoons of dish detergent to your sprayer. The surfactant disperses the chemicals and also helps cut through the waxy coating on thick leaves.

    the ivy has come off the brick wall, how do we reattached it ? The removal was an accident and we really want to reattach it.
