The most common use for Irish yews is for hedging. They grow naturally upright and are very easy to shape and prune, and can be pruned back to old wood and will re-sprout readily. The needles are straight with a fine tip. The trees produce red berries in the fall, but be cautioned as they are poisonous. The Irish yew reaches 7-8 ft high by 3 ft wide in 10 years, but can reach 20 ft high when mature. For a hedge, plant at 2 ft centers.
