The ivy has been pulled so now it's time to tackle your holly. Check out our short and sweet video (under 2 minutes) on "How to Remove English Holly". The moist soils we now have as a result of the recent rainfall, make easy work of uprooting small plants, so take this opportunity to use the weather to your advantage!

We hope that you'll watch it. share it with your neighbors and friends, and give us your feedback.

This is a broadleaf evergreen tree/shrub that is used as an ornamental. It’s native to the British Isles and can grow up to 50′ tall and 15′ wide, either as a single trunk or a multi-stemmed thicket. The glossy dark green leaves of English holly (Ilex acquifolium) are wavy with sharp, stout spines. The flowers are small and white and smell sweet. The female holly produces red or orange berries in the winter that are spread by birds (the berries are poisonous to humans). The plant also spreads by layering and suckering.

To control holly, which displaces native plants and shrubs in forest understory, you should pull up small plants when the soil is moist. Larger plants can also be removed with a weed wrench.  Mature trees have extensive root systems; the best way to deal with them is to cut the trees off at ground level and keep cutting off any suckers.

Some native plant alternatives to English holly are:

  1. Pacific waxmyrtle
  2. Tall Oregon grape
  3. Red elderberry
  4. Hairy manzanita
  5. Toyon
