A healthy tree provides shade, reduces noise and dust and recycles carbon dioxide. It is resistant to disease and better prepared in deterring insect attacks and damages. However, when the tree is in distress, it becomes susceptible to diseases and insect infestations. The distress may be caused by high temperatures, inadequate, either excessive or insufficient watering, poor soil quality, lack or excessive amount of nutrients, soil covered root flairs and screening by other trees or buildings, to name some. Typically the tree will start showing signs of distress after a year or two of unfavorable conditions. In some cases immediate treatment may save the tree, but in others the tree will not be able to recover, and will have to be removed. When the first signs of distress are noticed, it is important to call an Arborist in San Diego who will be able to determine the cause of distress and recommend appropriate treatment.
There are many signs of distress in trees. Leaves and branches are falling during the growing season resulting in thinner canopy. Leaves are smaller than normal. The color of the leaves is abnormal, and the same are easily affected by insect damage and diseases. The presence of fungus and mushrooms at the base of the tree trunk indicates decay and rot. Unhealthy looking bark and numerous holes is a sign of insect damage.
A common mistake gardeners make is the over watering. The over watering will cause yellowing of leaves, defoliation and wilted branches. In such cases watering must be minimized. The nutrients should be applied in the right season and in the right amount to avoid any harm to the trees. Excessive soil on the root flares also negatively affects the trees. For example, farmers have since long ago noticed that the trees with properly exposed root flares and well maintained soil system are less prone to the oak wilt. A tree in distress will benefit from proper aeration of the soil, as well as from the spraying the bark and the soil with Bio Wash, Cornmeal Juice or some other insecticide. Topping of the trees should be avoided, because it exposes the middle part of the tree to sunburns.
The best approach to having healthy trees in the yard is prevention. The preventive measures include timely pruning, tiling, nutrition, proper watering and others. Pruning will remove dead branches and the interlocking branches that rub against each other. Thus, properly pruned tree is less likely to face damage during a stormy weather or high Santa Ana winds. A certified Arborist in San Diego will be able to provide accurate and best maintenance methods for each tree in the yard.
