What condition is extensively linked to summer stress in turfgrass?

High soil temperature is extensively linked to summer stress in turfgrass because elevated temperatures can significantly impact the physiological processes of grass. During the hot summer months, soil temperatures can rise to levels that are detrimental to turfgrass health. When soils become excessively warm, turfgrass can experience stress due to reduced water availability, which can lead to decreased root growth and overall plant vitality. High temperatures can also increase the rate of evaporation from the soil, compounding water stress.

Additionally, high soil temperature can promote the growth of certain pests and diseases, further exacerbating stress in turfgrass. It’s important to maintain appropriate soil temperatures through proper irrigation and cultural practices to support turfgrass resilience during the heat of summer. Understanding this relationship helps turf managers implement practices that mitigate heat stress, ensuring healthier grass and improved aesthetics in landscaped areas.
