Heatwaves can cause soil to dry out, leading to stress for plants and delayed fruit production in vegetables like beans and tomatoes. Container gardens may require up to three waterings daily, and young trees are especially susceptible to damage during their first three years. Without proper care, plants may wilt, fail to bloom, or become more vulnerable to pests and diseases. Lawns can also suffer if cut too short or fertilized during extreme heat. These risks highlight the importance of proactive measures to protect gardens and landscapes during hot weather (source: pmg-ky2.com).
