Watering, Light, and Temperature Needs
Verbena plants have specific needs when it comes to watering, light, and temperature. Understanding these requirements helps maintain their vibrant appearance throughout the growing season.- Watering: Verbena prefers consistent moisture but can tolerate short dry spells. Water deeply once or twice a week.
