What to Do with Iris When Finished?
Iris plants, known for their vibrant and unique flowers, can bring a touch of elegance and beauty to any garden or landscape. However, when the blooming season is over, many gardeners wonder what to do with their iris plants. The good news is that there are several options to keep your iris plants healthy, thriving, and blooming for years to come.
Remove Dead Blossoms
The first step in caring for your iris plants after they’ve finished blooming is to remove the dead blossoms. Removing the dead flowers improves the appearance of the plants and prevents seed pod formation. This is because iris plants will focus their energy on producing seeds if they are not removed. By cutting off the dead flowers, you can encourage your iris plants to put their energy into producing new growth and storing energy for next year’s blooms.
Divide and Transplant
As iris plants mature, they can become overcrowded and may require division and transplantation. Bearded irises, in particular, should be divided every three to five years. This will help to prevent overcrowding, improve air circulation, and promote healthy growth. When dividing and transplanting, make sure to:
- Cut back the foliage to about 1/3 its original height
- Wash the soil from the rhizomes with a forceful stream of water
- Cut the rhizomes apart, making sure each section has at least one "eye" (the small, swollen stem that produces new growth)
Store Iris Rhizomes
If you’re not planning to transplant your iris plants, you can store the rhizomes in a cool, dry place until next spring. It’s essential to keep the rhizomes in a location with air circulation and a consistent temperature between 35°F and 45°F (2°C and 7°C). You can also wrap the rhizomes in newspaper or a dry cloth to protect them from moisture.
Care for Iris Plants in the Summer
While iris plants may not be actively blooming during the summer months, they still require care to stay healthy. During the summer, bearded irises should be provided with at least 6 hours of direct sunlight per day. You should also:
- Water the plants regularly, but avoid overwatering
- Fertilize the plants with a balanced fertilizer
- Deadhead any spent flowers or foliage to maintain appearance and prevent seed production
Common Mistakes to Avoid
When caring for iris plants, there are a few common mistakes to avoid:
- Not removing dead blossoms, which can lead to seed production and poor plant performance
- Not dividing and transplanting iris plants regularly, which can lead to overcrowding and poor growth
- Not providing enough sunlight, which can lead to weak and spindly growth
- Overwatering, which can lead to root rot and other problems
Conclusion
In conclusion, there are several things you can do with iris plants when they’ve finished blooming. By removing dead blossoms, dividing and transplanting, storing rhizomes, and providing proper care during the summer, you can keep your iris plants healthy, thriving, and blooming for years to come. Remember to avoid common mistakes and take the time to properly care for your iris plants. With a little attention and care, your iris plants will continue to provide beautiful blooms and add elegance to your garden or landscape.
