Tree diseases, symptoms, and treatments

Like any living creature, trees can get diseases and fungal infestations. Many tree diseases can go unnoticed, particularly if you’re not sure what to look for, and you may only notice there’s a problem once there is significant decay.

Symptoms of bacterial and fungal problems can grow randomly across the tree. Look out for wilting leaves that are dropping downwards and turning a dull greybrown colour. Sections of dead bark on the trunk of your tree can also indicate a problem, as the tree may not be getting the nutrients it needs.

As with human health, prevention is always better than treatment. Regular maintenance of your trees, including trimming, pruning, watering, and feeding is the surest way to keep your trees healthy and highlight any problems before they can cause significant damage.

Many diseases can be treated by pruning the affected areas, but if the disease or fungus has spread extensively the result may not be very attractive. An annual check by a trained arborist will give you the peace of mind that your trees are getting the best care possible and can help keep them looking good.

Some diseases must be treated with extreme caution. Kauri Dieback Disease, Myrtle Rust Disease and Dutch Elm Disease are easily spread and can be devasting for trees. It takes just a pinhead of contaminated soil to spread Kauri Dieback. Should you suspect any of these diseases are affecting the trees on your proper ty it would be best to get them checked by an expert as soon as possible.

Your trees are impor tant and keeping them healthy, and you happy, is one of our top priorities at BeaverTree Service.
