How to Propagate Iris
Let's talk about how to propagate irises and share some small experiences of green plant maintenance related to various iris propagation methods. Here are the detailed contents to follow.
Division Propagation: Perform division after flowering in spring or autumn, dig up the plant from the soil, and use a knife to cut the rhizome, ensuring each piece has 3 to 4 buds. Prepare a loose, breathable, and well-draining substrate, and after preparation, plant them separately with shallow planting, and they will soon resume normal growth.
Seed Propagation: Harvest the seeds promptly after they mature and plant them immediately in a suitable environment. They can germinate quickly, but it will take 2 to 3 years of care before they bloom.
One, Division Propagation
Division Time: Division propagation is one of the common propagation methods for iris flowers. It usually takes 2 to 4 years of cultivation before division can be performed to ensure survival rates. Division is typically done after flowering in spring or autumn, avoiding the plum rain season as the wounds can easily rot.
Dividing Rhizomes: Remove the iris bulb from the potting soil, carefully remove the soil from the bulb, making sure not to damage the bud area, as it can reduce the survival rate. Prepare a disinfected knife to ensure the wound does not get infected. After handling, cut the rhizome with the knife to ensure each piece has 3 to 4 buds. After handling, apply lime to the wound to disinfect and kill germs, and also cut off the leaves on the plant to reduce water and nutrient evaporation.
Preparing Soil: Iris flowers do not have high requirements for soil, but to ensure survival rates and promote vigorous growth later, it is best to prepare a loose, breathable, well-draining, slightly alkaline soil. You can mix the garden soil with an appropriate amount of river sand, wood ash, bone meal, etc. The prepared soil should also be disinfected before use.
Planting in Soil: Once the soil is ready and the rhizome is cut, you can plant it in the soil. Simply plant in multiple pots. When planting, control the depth, not too deep, just shallow planting. After planting, ensure the soil is slightly moist, and with a suitable climate, the plant will quickly resume growth, with a high survival rate and fast growth, blooming the second year.
Two, Seed Propagation
Iris flowers can also be propagated by sowing. Wait for the seeds to mature and harvest them immediately. There is no need to process the harvested seeds; just plant them directly in the soil. This method has a high germination rate and the seedlings can emerge quickly. However, iris flowers propagated by sowing grow slowly and need to be cultivated for 2 to 3 years before they bloom.
