As periods of drought become more common, protecting your landscape is no longer just about keeping things green—it’s about preserving the long-term health of your lawn, trees, and plant material. The good news is that a few strategic adjustments can make a significant difference in how well your yard withstands dry conditions.
Adjust Your Irrigation and Sprinkler Timers
One of the most effective ways to combat drought stress is by using water more efficiently. Instead of frequent, shallow watering, adjust your irrigation system to deliver deeper, less frequent watering sessions. This encourages roots to grow deeper into the soil, making turf and plants more resilient during dry periods. Early morning watering—typically between 4 a.m. and 9 a.m.—is ideal, as it minimizes evaporation and allows moisture to soak in before the heat of the day. Also, regularly check your system for leaks, misaligned heads, or overspray onto hard surfaces to ensure every drop counts.
Raise Your Mower Height
It may seem counterintuitive, but cutting your grass shorter during a drought does more harm than good. Raising your mower height allows the grass blades to grow longer, which helps shade the soil and reduce moisture loss. Taller grass also promotes deeper root systems, improving the lawn’s ability to access water stored below the surface. As a general rule, never remove more than one-third of the grass blade in a single mowing. This reduces stress on the plant and keeps your lawn healthier overall.
Apply Mulch to Retain Moisture
Mulch is one of the simplest and most effective tools for conserving soil moisture. Applying an additional few inches (no more than 2”) of mulch around trees, shrubs, and garden beds helps regulate soil temperature, reduce evaporation, and suppress weed growth that competes for water. Organic mulches, such as shredded hardwood or bark, also improve soil structure over time as they break down. Just be sure not to pile mulch against the base of trees or plants, as this can lead to rot and other issues.
Prioritize Plant Health and Soil Quality
Healthy soil acts like a sponge, holding onto moisture longer and delivering it to plant roots when needed. Consider incorporating organic matter, such as compost, to improve soil structure and water retention. Additionally, proper fertilization—done at the right time and in the right amounts—can strengthen plants and help them better tolerate drought stress. Avoid heavy fertilization during extreme heat, as this can further stress your lawn.
Choose Drought-Tolerant Plants
If you’re planning new plantings or renovations, consider incorporating drought-tolerant species into your landscape. Native plants are well-adapted to local conditions and typically require less water once established. Over time, this can significantly reduce your landscape’s overall water demand while maintaining curb appeal.
Drought conditions can be challenging, but with thoughtful care and a few proactive steps, your landscape can remain healthy and resilient. A well-managed yard not only survives dry spells—it continues to thrive despite them.
