What pairs well with African iris?
Several perennials grow well in beds with irises, including salvia, black-eyed Susan, phlox, sedum, daylilies, foxglove, yarrow, and hyssop. Late July through mid August is the best time to plant, move or divide iris. Iris is one of the most popular perennials in the garden and easy to grow.Shade and overcrowding are the most common culprits when irises won’t bloom. If your irises aren’t in full sun, move them to a brighter spot.Cut back irises after blooming and before winter to promote health and blooms. Removing unhealthy foliage helps prevent disease and pest problems.A few that do well are phlox, gaillardia, daylilies, pansies, and rudbeckia, which will bloom after the irises are finished. Early spring bulbs such as daffodils, anemonies, and hyacinth can provide color before the irises get going.
Do African irises like sun or shade?
Mature Size: 2-3′ tall x 3-4′ wide. Climate Requirements: African Iris performs best in full sun or part shade, in moderately fertile, moist, well-drained soils. Best flower production occurs in full sun, but light afternoon shade is welcomed. Planted too deeply Bearded iris rhizomes should be planted so the tops of the rhizomes are at or slightly below the soil surface. If planted too deeply, bearded irises will grow leaves but may not flower. Be careful, also, not to allow mulch to cover the rhizomes.Although irises can be transplanted at any time, they do best when established in the landscape from August to mid-October, said University of Missouri Extension horticulturist David Trinklein.Ensure these plants receive a minimum of 6 hours of sunlight daily; check annually for any changes in their sun exposure. Irises need at least 6 hours of sun per day if they are to flower to their fullest potential, and you should evaluate their location every year to ensure this demand is met.In areas with hot summers and mild winters, September or October planting may be preferred. We strongly suggest Iris be planted at least six weeks before the first hard frost in your area. Iris should be planted so the tops of the rhizomes are exposed and the roots are spread out facing downward in the soil.While irises grown from rhizomes—such as Japanese or Siberian irises—can be picky about spacing, bulbs typically only need a few inches of space. Any number of iris bulbs can be planted together. Just divide your iris bulbs when they become crowded or flowering is limited.
How often should you water African Iris?
Water. Provide regular watering — about 1 inch of water per week — during long periods of no rain. African irises are drought tolerant once established but grow best and produce better flowers when they receive water weekly. African Iris enhances garden aesthetics with its striking flowers and hardy foliage. This plant is low-maintenance and drought-tolerant, ideal for eco-friendly gardening. African Iris attracts pollinators, contributing to a healthy and thriving garden ecosystem.African Iris prefers a balanced fertilizer with equal parts of nitrogen, phosphorus, and potassium (N-P-K ratio of 10-10-10 or 14-14-14). Over-fertilizing can lead to leaf burn and root damage, impacting the overall health of the African Iris.In mid summer, when the plants begin to look ratty, cut all the foliage down by half to create “fans” of leaves. Always cut at an angle. At the end of the growing season, after the leaves have been killed by a few fall frosts, completely remove all foliage. Most of iris diseases overwinter on the leaf debris.For one, irises have a tendency to become overcrowded, which can lead to sad-looking plants and fewer flowers. Resetting a bed every few years by removing the older rhizomes and keeping just the younger divisions creates some breathing room and is a good practice.
Should African iris be cut back?
Iris plants are best cut back in the fall. Spent flower stalks can be removed in spring after the plants finish blooming, but the foliage should be left standing through summertime. In mid-autumn, cut the leaves back to about 3″ long above the soil line. Split the irises every year, after flowering has ended during June. At this point the early summer leaves and flower stems have started to die back, and the late summer leaves have started to grow. Split individual plants by cleaving the rhizomes with a spade, leaving the part to be retained undisturbed in the soil.Pick a location that gets at least six hours of sun every day and your irises will be happy. If you are in a very hot climate, irises will enjoy a bit of afternoon shade. Because irises grow in clumps, you can plant quite a few in a small space. Plan on spacing your clumps 18″ – 24″ apart.Generally, bearded irises are planted 12-18 inches apart, with the fan of leaves facing the same direction. If you have multiple cultivars, plant the different types in groups of three to seven rhizomes. After planting, water your iris and keep the soil moist (but not too wet) until new leaves begin to emerge.Irises don’t like high-nitrogen fertilizers, because they encourage soft growth that is prone to rot. Use a balanced 10-10-10 or low-nitrogen 5-10-10 fertilizer, or a superphosphate. Apply lightly in the early spring and again about a month after blooming is done. Sprinkle it around the rhizome, not on top of it.Perennials To Plant With Iris Alternately, Iris pairs easily with hyssop, heuchera, columbine, and delphinium to create drifts of flowers that float above their foliage. Layering early and late blooming perennials in the same bed can extend the color interest through fall.
What are some common mistakes to avoid when cutting back irises?
What are common mistakes to avoid when cutting back irises? Avoid over-pruning your irises and don’t make the mistake of cutting them back too early in the season. If you cut back too much or too early, you are removing the leaves that provide energy to the iris and the plant may weaken. Iris plants are best cut back in the fall. Spent flower stalks can be removed in spring after the plants finish blooming, but the foliage should be left standing through summertime. In mid-autumn, cut the leaves back to about 3″ long above the soil line.Cut down the leaves to within 4-6 inches of the soil, and compost if there are no signs of disease or pests. As the iris goes further into dormancy, the rest of the foliage will fall off and decompose in the garden over winter.Reblooming iris should be fertilized twice a year: once in early spring when new growth starts and again right after they bloom in spring. This helps encourage a second round of flowers in the fall. Use a balanced fertilizer, like a 10-10-10 formula, and water well after applying.Mid-July to early-September is the best time for dividing and transplanting bearded iris. This ensures adequate root growth and establishment before winter.
How fast does African iris grow?
Growth Rate: African Iris has a relatively slow to moderate growth rate, and it may take a few years to reach its full size. To see the second bloom, the conditions must be right, with full sun and rich, well-draining soil conditions. Bearded Iris prefer at least 6-8 hours of sunlight a day.Growth Rate: African Iris has a relatively slow to moderate growth rate, and it may take a few years to reach its full size.Because bearded irises multiply, there is no limit to how long they can live. Divide them every three to five years to extend their lifespan.Bearded irises should be divided every three to five years, as the plants quickly become overcrowded and don’t bloom well.
What are common African Iris problems?
Identifying signs of overwatering or underwatering is critical to maintaining the health of your African Iris. Overwatering can lead to root rot, characterized by yellowing leaves, mushy roots, and a general lack of vigor. Conversely, underwatering may result in dry, brittle leaves, and a wilted appearance. Once established, African iris will bloom year round. These flowers do not need to be deadheaded.In mid summer, when the plants begin to look ratty, cut all the foliage down by half to create “fans” of leaves. Always cut at an angle. At the end of the growing season, after the leaves have been killed by a few fall frosts, completely remove all foliage. Most of iris diseases overwinter on the leaf debris.Younger plants flower less, but within 2 years of its initial planting, the African Iris will begin to flower year round. Although the flowers are short lived, they are numerous; with each stalk producing a large supply of buds. The flower stems are perennials, and therefore do not need to be cut back once they flower.Use clean, sharp pruning shears to clip off spent flower stalks at the base to encourage continuous blooming in african Iris. Remove damaged or yellowing leaves at their base to keep african Iris looking tidy and to encourage fresh growth, but ensure not to harm the plant’s center from where new shoots emerge.
