How Frequently Do Iris Bloom?
From early spring to early summer, a variety of bearded varieties bloom. Numerous varieties in the Spuria subgroup of beardless irises bloom from late spring to midsummer. From mid-spring to early summer, certain Siberian iris (Iris sibirica) and Japanese iris (Iris ensata) selections bloom.
How Do You Make Irises Last Longer?
According to the USDA, Iris flowers last longer if they are cut early in the day when the buds are just beginning to open. Put them in a bucket of tepid water and cut the stem end at an angle of one inch up while they are submerged in the water. Keep your Iris out of direct sunlight and drafts by placing it in a shady spot. Remove and discard wilted flowers as soon as possible.
The Bearded Iris’s Bloom Time
Small to tall, Bearded Iris can be found in Oregon. The smallest of them start blooming in late March, and the tallest can start blooming as early as May. The Median Bearded Iris comes out in April, followed by the Tall Bearded Iris, which starts to fade early to mid-June. The color show lasts through May. Each variety blooms for about two weeks, based on the weather.
Some Tall Bearded Iris bloom early, and some bloom late, so try both to make your season longer. The Intermediate and Standard Dwarf Bearded Iris are small bearded Iris that can add a month to the start of your bloom season. Finally, think about the reblooming Iris, which can bloom again and again. They can do this in the summer and fall, so think about them.
How Do You Keep Irises Blooming Throughout the Summer Months?
One of the best things you can do for your irises is to water them every day. Don’t forget to water them during the day and at night. Many people have their plants’ roots rot when they don’t water them at the right time of day, which happens a lot in the summer.
Another important tip is to mulch your plants. This will help keep the soil moist and cooler, which is beneficial for your irises. Mulch also helps suppress weed growth and keeps the soil from becoming too hard.
Make sure that you do not over prune your irises. Over pruning can cause the plant to lose energy and focus on growing new leaves instead of flowers. Keep it simple and give your irises the water, nutrients, and sunlight needed to thrive!
Because of the close living relationship between Iris and the surrounding soil, weeds must be kept a healthy distance away. Mulching around your plants can help prevent weed growth and provide a buffer for rainwater runoff into potting soil. It also helps keep moisture in the ground, which will provide more nutrients to your irises throughout their entire life cycle from germination through summer bloom!
Finally, make sure to fertilize your plants regularly. The best time to do this is in the early morning or night when the plants are not actively photosynthesizing.
Is It Necessary To Remove Dead Irises From the Garden?
After all of the buds have opened and begun to fade, trim the stem to the base. Use shears or a sharp knife to cut the base of the stem. After they’ve finished blooming, deadhead repeat-blooming iris varieties a second time in late summer or early fall. Removing all of the dead flowers and stems from the bed is necessary.
