Ensure you consistently monitor soil moisture levels to prevent overwatering or underwatering. Adjust watering times to the early morning on days with extreme heat.
Mulching also prevents heat stress for plants. Organic materials like wood chips or shredded leaves act as a barrier, retaining soil moisture and stabilizing soil temperature.
Another option for protecting hostas from the sun’s harsh rays is using shade cloth. Place it over the plants in strategic locations, especially during peak hours of sunlight.
