Trees are most vulnerable in their first years of life and should be tended with special care. Newly planted trees should be watered deeply and on a regular basis. Allowing a hose to drip at the base of a tree for several hours will permit the water to soak deep into the soil and encourage deep rooting. This will give the tree a better chance of surviving drought.
Many personal decisions go into tree planting. In areas with hot summers and cold winters it is best to plant deciduous trees. These trees will provide shade in the summer but will allow desired sunlight to pass through in the colder months. Some trees are better than others for providing a buffer against noise and unwanted views. Also, personal expectations should be considered.
