Yew Trees

From magic to mythology, the Yew tree has impacted the world well beyond its roots in horticulture. In ancient times the small specimen was revered for its ability to remain green year-round. These days the evergreen is still prized, though more for its landscaping value than its supposed secret powers. Homeowners looking to grow a natural border around their property often select the Yew tree to create a dense green boundary.

One of the most noteworthy characteristics of the Yew tree is its longevity. Some trees have survived for more than 2,000 years; however, the oldest Yew on record is estimated to be about 5,000 years old. It can be found in Perthshire, Scotland, where it maintains the same identifying features as its younger cousins:

  • Leaves: Flat, needle-shaped leaves which stay green throughout the year.
  • Fruit: Bright red berry-like fruits called "arils" contain a highly poisonous seed which can harm humans and livestock. The sweet flesh surrounding the seed is safe to consume and is often eaten by birds.
  • Bark: The tree's reddish bark is highly malleable, yet incredibly durable. Its flexibility makes it a prime material for bows and fence poles. In addition, the tree's thin, scaly bark flakes off quite easily, especially if it is exposed to excessive sunlight.

The slow growing tree ranges in height from one to 50 feet tall, with some rare specimens exceeding 80 feet.

Roughly eight different species of Yew trees exist throughout the world. Among the most prevalent are:

  • Japanese Yew: This type of Yew is often used as a bonsai tree. While it can grow upwards of 45 feet tall, it is typically pruned into shorter, decorative topiaries. Its leaves remain dark green throughout the year while its fruit ripens in the summer months. The Japanese Yew does not tolerate drought conditions and cannot survive exposure to temperatures below -25 degrees Fahrenheit.
  • European Yew: A typical European Yew will reach heights of 40 feet, though it is often pruned to form tall dense borders or privacy screens on properties. The European Yew has dark green leaves, red berries, a long life span and a slow growth rate.

Three other Yew tree types—Florida, Mexican and Pacific—are so rare they often appear on the list of threatened or endangered trees. In fact, in the early 1970s, the Pacific Yew was removed from the commercial tree market after scientists found the tree's bark contained taxol. Taxol, the compound used to create a powerful cancer-fighting drug, led to the tree to being overharvested in parts of North America. Consequently, a ban was put in place to keep it from becoming extinct.

Where the Yew Grows

The Yew is a hearty tree capable of surviving in a variety of soil types including limestone and chalk, though it prefers moist, well-drained soil. The Yew tree thrives in full shade, though it can withstand small amounts of sunshine. In order for the Yew to survive, it should not be exposed to excess water or high winds which can punish the small tree.

Yew trees are often found lining cemeteries and churchyards throughout Great Britain and Ireland. It also prospers in most of Europe, Asia, North Africa, and Iran, as well as parts of North America.

In the United States and Canada the Yew tree is typically used as a hedge. There are very few tall Yews in North America. Rather, the tree resembles a shrub and is more tolerant of cold weather than its taller counterparts. Regardless of their size, Yews should not be planted in areas where kids or pets play due to the toxicity of its fruit. If you own grazing livestock, you might consider fencing off Yew trees in order to avoid having the animals ingest the poisonous red arils.


Popular Uses

During the Middle Ages, Yew wood was used to craft spears, bows, and darts until the advent of firearms. Since then, the wood has been reserved to make ornate weapons, bowls and tool handles.

Today, the Yew tree's wood remains a hot commodity, especially with bow makers.

The tree also has medicinal value. Prior to advances in modern medicine, flesh from the tree's berries was used to treat heart ailments and problems with the cardiovascular system. More recently, the tree's bark and leaves have been found to contain taxol, which is used to treat cancer patients in an effort to stop cell mutation.


Interesting Facts

The Yew's mystical symbolism is well documented over the ages. In ancient Europe the trees were planted to guard cemeteries, as it was widely believed that the Yew had powers to ward off evil spirits and help souls find the afterlife.

Other interesting facts about the Yew tree include:

  • Yew sprigs were once used as diving rods to help locate lost items.
  • The Celts placed the Yew on a short list of sacred woods.
  • Swiss mountaineers call the Yew "William's tree," in memory of William Tell.
  • In Austria, the Yew tree is planted near main squares to bring luck to village affairs.

Yew hedges are also used to create mazes to decorate public green spaces.

Yew Diseases

The Yew tree may appear dense and sturdy, but it is susceptible to a number of diseases, including:

  • Root Rot: This disease attacks the tree when it is made to sit in excessively wet soil. Symptoms include wilting leaves and black, rotting roots. In severe cases, the disease can kill the tree.
  • Needle Blight: This fungal disease preys on the tree's tissue and causes spotting or wilting foliage. If left untreated, the blight will spread from the needles to the twigs, and eventually infect the entire tree.
  • Sooty Mold: This black fungus is caused by the presence of mealybugs and scale which emit a sweet substance that is left on the tree's leaves. The mold is a direct result of untreated insect infestation.

In addition to these diseases, Yew trees can also sustain damage from cold winds. Excessive exposure to dry, cold winter winds and direct sunlight can cause major damage to the tree. To avoid winter drying, avoid planting Yews on the south or southwest sides of buildings.


Yew Care

Yews are a popular choice for topiaries, though you need to prune them on a regular basis if you want to maintain their shape. Once the evergreens are placed in the ground as a hedge or shrub border, you can enhance their ornamental value by following these simple tips:

  • Add compost to the base of young Yew Trees.
  • Water the tree generously immediately after you plant it. However, once you notice that the tree is acclimating to its new home, reduce the amount of water you give it.
  • Yew trees need full to partial shade to thrive. Do not plant a Yew in a spot where it receives excessive sunlight all day.
  • Remove other plants that may interfere with the Yew tree's spread. Some species can grow as wide as 20 feet.

Finally, while Yews respond well to trimming, don't overprune the tree while it is in its infancy as you may interfere with its growth.
