If you want to keep your Leylandii for a long time, you ought to know the common diseases that may attack your trees. Knowing the symptoms seen on the tree will enable you to detect them at an early stage hence provide a solution the quickest time possible and avoid letting the disease reach a state beyond recovery. Read on to find out the common problems encountered by a gardener on Leylandii trees.



Have you noticed some brown patches on your Leylandii hedges lately? Do not overlook it and think it may just be an unhealthy part of the hedge not getting enough sunlight. That brown among greens is a sign of the infestation of the Cypress Aphid. They may have been there longer than you might expect, since it is pretty difficult to see them under a thick growth of a hedge. In fact, in recent years, many hedges have been destroyed by this bug. They usually kill the plant by sucking sap from its branches. Advances in gardening have led to the development of insecticides to neutralize this bug. You can visit your local dealers or consult an expert to determine which one will be best for you.



Another disease of the Leylandii is the Botryosphaeria canker. Don't worry too much about the fancy name. If ever you notice that the branches of your Leylandii tree are developing reddish-brown sections yet with healthy leaves, then the tree may be infected with this fungus. Even if an effective chemical control is not readily available, you can still manage to salvage the tree by keeping them properly watered especially durin
g dry periods and cutting the dead branches to avoid further contamination of other neighboring branches.



Another fungus called Cercosporidium sequoiae affects the Leylandii and the disease is known by the name Cercospora needle blight. One of the symptoms includes browning of the needles in the lower crown next to the stem. The fungus appears as small green pustules on the surface of the needles or sometimes even on twigs. Fungicides are available against this disease. If intending to use one, always follow the advice of experts on their use so as not to endanger the total health of the Leylandii hedges and neighboring trees.



Root diseases also affect the Leylandii. One of these is the Annosus root rot. The fungus responsible for the disease will cause a yellowing or a reddening of the foliage of the tree which happens slowly and overtime. This can be described as a slow killer since you will just notice a decrease in the overall health of the tree, eventually leading to its death. At certain occasions, though, even without any outward appearance of the presence of the disease, the entire tree may just fall off. Only after investigation is it revealed that a root disease has infected the tree.



Proper care still remains to be the best solution to prevent the onset of any disease. Keeping your Leylandii healthy is a must for any gardener.
