Water, water, everywhere

In reading the county extension agent's column last week in our local newspaper, I realized I needed to take better care of my trees. I got out the soaker hose, and am in the process of soaking the perimiter, called the drop line. I have two young trees to water, so I will be at it all day. Apparently, if you just water the base of the tree, the roots won't get sufficent water. My goal is to defeat the drought and have lovely, green, leafy trees to enhance the beauty of the neighborhood.
