What do cool-season plants typically require for optimal growth?

Cool-season plants thrive in moderate temperatures, as they are adapted to grow best during the cooler months of spring and fall. While they can tolerate some heat, high temperatures can actually hinder their growth and overall health.

Moisture plays a crucial role in their development because these plants require consistent moisture levels in the soil to maintain their health, support photosynthesis, and enable nutrient absorption. Excessive dryness can stress the plants, leading to stunted growth and poor performance.

Shade is not a primary requirement for cool-season plants, as many benefit from full sun exposure. Fertilization is beneficial for promoting healthy growth but is not an absolute requirement for optimal growth; rather, it can enhance the health of the plants when needed.

Therefore, moisture stands out as the most critical element that cool-season plants require for optimal growth, aligning with their natural preferences and environmental adaptations.
