Drought Water Priorities
Trees need an inordinate amount of water. A good-sized tree may draw a few hundred gallons of water on a hot day. As you look across any Sacramento lawn, you'll notice the absence of standing water; the fight for water is below the surface. Grass, shrubbery, and trees are fighting for every drop of common ground water. Grass will grow back, shrubs tend to be durable and are, at least, easily replaceable. Trees are not. Your fifty year old oak can be fully replaced but not in your lifetime. In terms of illness, disease, and life-cycle, trees are more like mammals than they are like grass. Past a certain point of decline, a tree cannot be restored. The answer is prioritizing water.
Clear grass and other plants from the base of your tree. The more cleared earth you can afford the tree, the better the tree's chances for an adequate water supply. Obviously, you can't reasonably remove all the grass from under the canopy but clear a 24" ring around the base of the tree. Large trees will benefit from greater cleared space. Position sprinklers to water the earth around the tree (within the tree's drip-line) instead of the lawn. Water needs to be under the tree but not on trunk. Even twenty minutes of light watering every other day can make a difference for most trees. Freshly planted trees require a bit more water.
Fortunately, trees are tough and tend to be long-lived, which means they have excellent survivability. We're going to continue to lose trees during this drought but we're losing more than we must. Prioritizing your outdoor water-use may be the extra bit of help your favorite tree needs to get through dry times.
