Bay Laurel Tree


Everything you need to know about the bay laurel tree, from identification tips to typical characteristics; how to spot disease and the best way to maintain a bay laurel tree.

The bay tree or bay laurel makes a popular hedging and topiary shrub thanks to its attractive glossy, aromatic leaves that stay green and therefore offer privacy year round. Of Mediterranean origin, this tree is famous for its culinary leaves that are used fresh or dried in cooking to flavour casseroles, soups, bolognaises and other dishes.

You’ll often see the bay laurel tree formally and neatly clipped into eye-catching shapes on estate land, but it is an equally popular entrance plant that does very well in patio pots offering an elegant welcome to any home. In colder climes the bay tree will often be found as an indoor plant.

Bay Laurel Trees and Wildlife

Small mammals will also take cover within the privacy of the year-round dense greenery.

Bay Laurel Tree Symbolism and History

In Greek mythology, Daphne the female nymph turned was turned into a laurel tree by her father Ladon, the river god, in order to save her from the god Apollo’s affections.

Ancient beliefs dictate that the laurel tree held magical powers and an ability to ward off evil witchcraft and disease. For the Greeks, bay laurel was a medicine that would provide protection against diseases, in particular the plague.

Both the ancient Romans and Greeks would wear bay laurel wreaths as a status symbol and to denote victory.

Bay laurel was widely used as a herbal medicine for conditions such as colic, renal problems and stomach issues, as recorded by monks in ancient handwritten medical journals.

The Importance of Bay Laurel Trees

Bay leaves in their dried form are commonly used in Italian cooking but because of their sharpness they are usually removed from a dish before serving.

Ground bay leaves are used widely in stocks and soups and are more easily digested than their whole counterparts.

The berries of the bay laurel and the oil of the leaf are also used for culinary purposes, and the wood of the tree can be burnt for smoke flavouring for meat and fish.

The bay laurel leaf produces an essential oil that is used in aromatherapy although it is generally mixed with other oils such as eucalyptus and lavender or heavily diluted with a carrier oil so that it can be safely used to alleviate muscle aches and pains, sprains and rheumatic ailments. Bay laurel oil is also said to be good for stimulating hair growth and treating dandruff as well as having a positive effect on the lymphatic system.

When combined with eucalyptus oil, bay laurel essential oil can assist with respiratory related conditions such as persistent cough and bronchitis. It also acts as an effective digestive aid.

Caring for a Bay Laurel Tree

In general, the bay laurel does not require much pruning, although topiary shrubs will need fairly regular pruning in order to maintain their shape, and bay laurel hedges will need careful pruning to keep their neat shape. August is the prime time for pruning hedges and more established plants that have outgrown their space can be carefully pruned back to ground level in spring and will as a result sprout back very rapidly.

There are various things to look out for when growing a bay laurel tree. Leaf spots are a result of waterlogged roots or just general wet weather. If you are growing your laurel tree in a container then you will find this happens quite a lot if the compost has not been renewed for a while. If this is the case, be sure to repot into fresh compost that is well-drained.

If you spot yellow leaves then this could be a sign of nutrient deficiency which could stem from waterlogging or damage caused by cold weather. Winter cold and varying moisture levels in the soil can also cause the bark to peel, although bay laurel tree owners should not be overly alarmed by this. Simply prune any dead parts back to the green, healthy wood.

Other issues to look out for include brown leaves and infestations of insects including the bay sucker and soft and horse chestnut scale.
