Summer

Check root-zone moisture first. Brief wilting during the hottest hour may pass by evening, especially if the plant looks healthy in the morning. A dry root ball needs water, but extra watering in wet soil can worsen the problem. Also assess overheating, emitter performance and recent transplanting.

Check the root ball and water if needed, then provide temporary shade while retaining airflow. A net on a separate support is preferable to sealed plastic on leaves. Avoid combining heat with unnecessary transplanting, heavy trimming or intensive feeding. Gradually restore the normal routine when temperatures fall.

No. A short shower may wet only the surface, while soil beneath crowns or beside walls remains dry. Check how deep the water reached and assess containers and new plantings separately. If the required layer is already moist, reduce or skip watering. Decide from the soil, not just the occurrence of rain.
