Care Instructions
Iris unguicularis requires bright, direct sunlight for optimal growth. It prefers moderate temperatures and can tolerate cooler conditions. The plant should be watered sparingly, allowing the soil to dry out almost completely between waterings. It thrives in moderate humidity levels.Soil
This plant prefers well-draining loamy soil. It is important to ensure that the soil does not retain too much moisture, as this can lead to root rot. A soil mix that includes sand or grit can help improve drainage.Fertilizer
Iris unguicularis benefits from a balanced fertilizer with a nutrient composition of 5-10-10. Fertilize the plant in early spring and again in late summer to support its growth and flowering.Repotting
Repotting should be done every 2-3 years, preferably in the fall after the blooming period. Carefully lift the rhizomes, divide them if necessary, and replant them in fresh, well-draining soil.Propagation
Propagation is typically done through division of the rhizomes. This should be carried out in the fall. Ensure each division has a healthy portion of rhizome and roots before replanting.Pruning
Pruning is necessary to remove spent flowers and dead foliage. This should be done after the blooming period to encourage new growth and maintain the plant's appearance.Toxicity
Iris unguicularis is not known to be toxic to pets or humans. However, it is always advisable to handle plants with care and wash hands after gardening.Additional
To encourage blooming, ensure the plant receives adequate sunlight and avoid overwatering. Mulching around the base can help retain moisture and protect the roots during colder months.REVOLUTIONIZE YOUR PLANT CARE
