Celebrate Smart Irrigation Month in the home landscape

By Sadie Lackey

Landscape irrigation can be tricky, especially in the summer. During the month of July — Smart Irrigation Month — University of Georgia experts have advice on how to use irrigation as efficiently as possible.

Be aware of the conditions of the landscape

Typical lawns and plants require 1 to 1.5 inches of water per week, said Rolando Orellana, an urban water management agent with UGA Cooperative Extension.

Consider the water source, air circulation, slope, drainage and other conditions of the landscape when creating an irrigation plan.

“Make sure you know the plants in your garden,” Orellana said. “Not all plants have the same water requirements. You can ask your Extension agent to find out more information about plant water requirements."

With this understanding, individuals can ensure that the root systems of plants are in top shape. It is best to apply deep and infrequent watering to establish strong root systems and healthier plants. Applying small amounts of water frequently will create a shallow root system and more water evaporation. It is ideal to have an irrigation schedule and system that replicates rainfall to ensure landscapes are not overwatered and plants stay healthy and beautiful, Orellana said.

Where, when and how?

The best time to water landscapes is between 4 a.m. and 9 a.m., keeping in mind that deep, infrequent watering is best to avoid waste, run-off and evaporation, Orellana advises, adding that gardeners should water by hand when possible, as it is the most effective method of ensuring that water is delivered only where needed.

Using irrigation equipment

While hand-watering is preferred, it is not always practical. When using irrigation equipment, be thoughtful about how, where and how often to turn on your sprinklers. Before setting up portable sprinklers, soaker hoses or an in-ground irrigation system, consider the following:

  • How much of the landscape needs to be watered?
  • Where can the equipment be placed to reach the maximum amount of area and provide even coverage? 
  • Where are the outdoor water sources located, and where can one be added if needed?

From there, choosing between systems such as soaker hoses, a drip irrigation system or a sprinkler system becomes easy, Orellana said.

To reduce waste and get the most efficiency out of irrigation equipment, Orellana suggests installing rain and moisture sensors. He also recommends making a periodic inspection of irrigation part of a regular landscape maintenance routine.

“Most people experience issues with plant growth,” Orellana said. “Sometimes irrigation systems have broken parts, occasioning water leaks and waste. These problems are often left unattended due to lack of irrigation system monitoring and auditing. Check system pressure and flow and make regular inspections to help save water and dollars in the process.”

UGA uses AI, robotics to improve Georgia’s Vidalia sweet onion crop 10/23/24 Jordan Powers
A multidisciplinary team of UGA researchers aims to enhance the competitiveness of Vidalia onion growers in Georgia by providing them with the ability to confidently detect onion diseases early, enabling them to make management decisions on their crop at a critical time. These abilities, researchers say, should result in increased yield and quality of marketable onions and an overall increase in efficiency and productivity.

Upcoming UGA plant sales bring color to fall 10/15/24 Maria M. Lameiras
Fall weather means fall gardening, and several groups at the University of Georgia’s College of Agricultural and Environmental Sciences will be offering the fruits of their labors at ornamental plant sales across campus this semester. On Friday, Oct. 18, the Trial Gardens at University of Georgia will hold its annual Fall Houseplant Sale, and on Wednesday, Nov. 20, greenhouse management students will offer their ornamental plant sale at the South Milledge Greenhouse Complex.

It’s a special moment to step inside Sanford Stadium and walk across that sprawling green field between the hedges. While the grass beneath your feet may not always be your first thought at the Freshman Welcome or Commencement, it is for Gavin Shytle. Keeping the turf safe, healthy, and aesthetically pleasing is the sworn duty of Shytle and his fellow turfgrass management majors. Before athletes even hit the ground running, he makes sure the ground is prepped for them.

Participants in UGA Extension's Master Forager program find a taste for the wild 09/19/24 Becky Mills
On an unseasonably warm winter afternoon, three women armed with baskets and shears made their way along a nature trail in the woods of Pike County, Georgia. Peering into the underbrush, they stopped occasionally to examine spots of interest in and under the trees and around fallen logs and decaying stumps. A curious observer might wonder what they were searching for with such intent — unless they overheard the trio’s conversation. 
Most of Georgia’s vegetable crops are grown in the southern part of the state, which, similar to California, faces drought risks. However, as the climate warms, the area is expected to receive slightly more rainfall than usual, according to CAES economist Jeff Mullen. If vegetable production in California decreases and prices rise elsewhere, Southeast producers may consider shifting from row crop to vegetable production. CAES News
Georgia vegetable production may expand as a result of climate change 09/17/24 Maria M. Lameiras
Changing weather patterns are influencing cropping systems and where certain crops can be successfully grown. Researchers in the University of Georgia’s College of Agricultural and Environmental Sciences recently published a study in the journal Sustainability examining the feasibility of expanding fresh vegetable production in Georgia as increased temperatures and more frequent and extreme droughts threaten producers in the Western United States.
