Many yards have sprinkler systems because we all have grass, which is only a problem when you decide to plant something other than grass or annuals. Most perennials, shrubs, and trees, especially conifers, prefer to not have their leaves sprayed with our heavy salty and chemical water, especially if you are using irrigation water to water your yard. This type of water leaves a residue on the leaves and needles of the plants and trees blocking their ability to receive sunlight and photosynthesize, slowing the growth of the plant and in time frustrating many plants so much that they die.
Most trees drop their leaves in the fall and grow new ones in the spring, residue free until they are coated again. Most conifers, on the other hand, will eventually die from being coated with the residue of the water because they don’t drop their needles. Using a drip line for your trees, shrubs, and perennials is recommended to help your beautiful landscape flourish.
Drip lines also help conserve water because the water doesn't evaporate before hitting the ground like some of it does when using a sprinkler, therefore, requiring less water. They also help concentrate the watering on the exact area that needs the water providing a more efficient use of the water. Drip lines are beneficial in many ways for non-grassy areas and should be considered when planning the irrigation system for your yard.
