How to propagate Iris lactea

Iris lactea can propagate and grow new plants, usually by sowing or asexually, such as by division. So how does Iris lactea propagate? Let's see three propagation methods of Iris lactea.

Sowing propagation method of Iris lactea

Iris lactea can be propagated by sowing, but the drawback of seeding is the low emergence rate of seeded seeds.

When iris lactea is sowing, the temperature of seed germination is between 15℃ and 30℃. If the temperature is not appropriate, then the germination rate will be very low. Before sowing, it is generally required to promote germination, which can be soaked in warm water to improve the germination rate of seeds. Seed collection is suitable for November, cut off the inflorescences of Iris lactea, take out the seeds, sowing in February or March, sowing can be used in the way of drill. If the temperature is low, it can be covered with plastic film insulation.

It should be noted that the seeds of Iris lactea do not germinate well at room temperature. If the seeds are stored for more than 5 years, their vigor will decline. Generally, they will be stored at variable temperature.

Division propagation of Iris lactea

Division propagation of Iris lactea can generally be carried out throughout the year, but spring and autumn are the best time for reproduction. Divide Iris lactea into plants, and then plant them in clusters of 2-3 plants.

Keep three to five leaves from each new plant of Iris lactea, and cut off the rest. The survival rate of replanted plants is higher, pay attention to the high temperature when shading.

Rhizomes propagation method of Iris lactea

Iris lactea can also take the way of rhizomes propagation, generally can be carried out throughout the year, but also in the spring and autumn is better. Cut the underground rhizomes of Iris lactea into about 10cm long segments with several bell buds in each segment. When planting the roots, you can put the roots into a trench, shoot up, spread the roots, cover with soil, and then pour water. Plastic film can be covered when the temperature is low, and shading is necessary when the temperature is high.
