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.

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. 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.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. Although they provide pleasure for many years with little care, periodic dividing is an important cultural practice for maintaining plant health.Reblooming iris should be fertilized twice a year: once in early spring when new growth starts and again right after they bloom in spring.

In the case of some varieties of Iris, you may get a second flush of blooms if you deadhead your plants.Cut back irises after blooming and before winter to promote health and blooms. Removing unhealthy foliage helps prevent disease and pest problems. Divide irises every 3 to 5 years to avoid overcrowding and encourage flowering.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.
What happens if you don’t cut back iris?
Pruning or trimming the foliage protects the plant from fungal and bacterial diseases caused by too much moisture on the leaves. Irises are vulnerable to blight, leaf spot, and soft rot. Left to overwinter, they are also vulnerable to a major iris pest, called the iris borer. Key Points. Cut back irises after blooming and before winter to promote health and blooms. Removing unhealthy foliage helps prevent disease and pest problems. Divide irises every 3 to 5 years to avoid overcrowding and encourage flowering.The companion plants for iris should thrive in the same conditions.

African irises are drought tolerant once established but grow best and produce better flowers when they receive water weekly. An amendment of superphosphate, colloidal phosphate, or bone meal applied in early spring can help plants develop blooms. Another reason for iris plants not flowering is overcrowding. The rhizomes will increase over time and plants become too packed in their site.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.Reblooming iris should be fertilized twice a year: once in early spring when new growth starts and again right after they bloom in spring.

What is the best fertilizer for African irises?
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. It is not advisable to use Miracle-Gro potting soil or all-purpose plant feed on irises as the products are high in nitrogen. Irises want to be fertilized with low-nitrogen feeds, so look out for products where the ratios of phosphorus and potassium are equal to or higher than that of nitrogen.Specific watering information depends on your climate and your soil, but keep in mind that deep watering at long intervals is better than more frequent shallow waterings.
