tall bearded iris

For optimal growth, tall bearded iris plants need to be watered increasingly in the spring as the weather gets warmer and precipitation becomes more unpredictable. During the summer months, they should be watered deeply once every 1-2 weeks, depending on the weather and amount of rainfall. During the hottest parts of the day, you should avoid watering your iris as much as possible, as this can lead to leafburn and stressed plants. During the winter, the iris should be watered minimally, especially in areas that receive very cold temperatures, as this can lead to root rot and can be detrimental to the plant. Your Iris 'America's Cup' should be watered on an as-needed basis, and allow the soil to dry out before each watering session.

Tall bearded iris (Iris 'America's Cup') requires about 5 to 6 hours of sunlight per day to thrive. When grown in high heat and direct sunlight, the iris can become wilted and may even suffer from sunburn. For this reason, it is best to provide the plant with partial sun or light shade, especially during the hot summer months. During the spring and fall months, the tall bearded iris can tolerate direct sunlight, ensuring it receives enough sunlight to flower throughout the season.

Tall bearded iris (Iris 'America's Cup') should be pruned in early spring once the danger of frost has passed and new growth has started. Start pruning by removing any dead or damaged foliage - this will ensure the healthiest plants and strongest blooms. It is best to cut off all the flower stems. By doing this, you will help the plant to focus on developing stronger foliage and roots instead of blooming. Additionally, you can remove any overly thick or large leaves to keep the foliage from becoming overcrowded and reduce the need for fertilizing. Finally, it is important to trim back the iris leaves to about 10 inches to encourage new growth and aid the plant in conserving energy and resources. This pruning method will ensure healthy and vibrant plants and an abundance of flowers each year.
