Climate change is causing shifts in weather patterns, resulting in longer droughts, stronger storms, increased flooding, and more intense fires. These changes are largely driven by higher levels of greenhouse gases in the atmosphere due to human activities such as burning fossil fuels.
Gardeners can play a role in both adapting to and mitigating climate change by making thoughtful choices about plant selection and garden management. According to Sara O’Keefe, “There’s adaptation and there’s mitigation of climate change, and the right plants can contribute to both. Plants help mitigate the effects of climate change in air and water by removing pollutants and sequestering carbon keeping it out of the atmosphere. Happily, gardeners can contribute to climate change solutions by adopting some new practices with water, soil, and plant management.”
With rising temperatures, plants will require more water. Water conservation methods such as drip irrigation systems with timers can provide efficient watering without waste. Mulching helps retain soil moisture, while rain barrels can collect additional water from rooftops.
Soil health is also crucial for climate adaptation. Healthy soils store carbon and retain water better than degraded soils. Large plants like trees move carbon from the air into the ground. Composting or growing cover crops improves soil fertility and moisture retention while helping bury carbon underground. To control erosion during rainy seasons, ground covers like low-growing native plants are recommended alongside structures such as swales or rain gardens.
Selecting native or climate-appropriate plants is another key strategy. These species typically require less water during dry periods but can handle wetter winters. They also support pollinators like bees, butterflies, and birds by providing food sources such as nectar and pollen.
As climates warm and planting zones shift, gardeners may need to adjust planting dates for food crops and choose varieties that ripen quickly or tolerate heat and drought conditions. Rotating crops prevents soil depletion; integrating herbs with flowering plants attracts beneficial insects; perennial edibles offer sustainable harvests with lower water needs once established.
Fire safety is an important concern in areas prone to wildfires. Removing invasive species—including juniper, Italian cypress, and bamboo—can reduce fire hazards around homes. It is advised to clear all plant material within five feet of buildings to minimize ember risks; between five and thirty feet from structures, use well-irrigated low-growing plants separated by non-combustible materials like rocks or gravel.
For larger spaces beyond this defensible zone, keystone species such as oaks or willows provide habitat for wildlife while Toyon offers winter berries for birds. Proper spacing between plants along with regular pruning reduces fire risk further.
O’Keefe emphasizes ongoing vigilance: “All plants can burn, but the right plant in the right place with the right maintenance is good gardening… As climate change alters the environment, watch for new pests and invasive plants as you adapt to and mitigate the damage. You are part of the solution to climate change problems.”
