Bród iris love the sun, which is why we plant them in a place where they will have at least 6 hours of sun per day. The soil should be well permeable, with neutral or slightly alkaline. In contrast, Siberian and Japanese irises prefer sunny or slightly shaded positions. They need moist, fertile soil with acidic (especially Japanese irises). Drought -resistant irises are resistant to drought, but in flowering and in hot weather it is worth watering them. Siberian and Japanese irises require regular watering, especially during drought. Flowers are fertilized in spring, after moving vegetation, with a multi -component fertilizer for flowering plants. It is better not to use nitrogen fertilizers because they are conducive to leaf development at the expense of flowering. What to do with irises after flowering?
Irises after flowering. What to do with flowers?
When the flowers lose their beauty, we cut off the faded inflorescences. Thanks to this treatment, plants will not produce seeds. All energy will be redirected to the rhizomes. However, we leave the leaves. The green parts of the plant will take nutrients from the ground and the process of photosynthesis will take place. We shorten them only in late autumn to a height of about 15 cm above the ground. We exaggerate chin irises every 3-4 years to prevent the thickening of rhizomes and weakness of flowering. We exaggerate Siberian and Japanese irises, every 5-6 years.
