How does the fringed iris propagate? A detailed introduction to propagation methods
The fringed iris is a very well-known early spring flower today, called cold-tolerant; the duration of sunlight exposure has a greater effect than light intensity, and it is often grown as a biennial plant. Some flower enthusiasts grow the fringed iris in pots at home and also like to propagate it themselves. Generally, the fringed iris can be propagated by division, cuttings and sowing.
Fringed iris
Division propagation of the fringed iris is carried out during the dormant period in early winter or early spring. First dig the old fringed iris plant out of the soil, cut the rhizome into individual plants with 2-3 buds each, and plant them once the cuts have dried. Alternatively, after the fringed iris has bloomed, cut off the leaves more than 30 cm above the plant and divide it into clumps of 2-3 plants each for planting out; with this fringed iris division propagation method, they generally only bloom in the 3rd year.
The cutting propagation method for the fringed iris is usually carried out in spring. Cut the rhizome of the fringed iris into 6-8 cm cuttings, then insert them into a sand bed at a temperature of 20°C, leaving 1-1.5 cm of the fringed iris tip exposed. Water thoroughly at first, and afterward make sure the sand bed maintains a certain humidity. After about 2 weeks, the fringed iris can sprout and form independent new plants; when the new plants have put out 2-3 new leaves, the seedlings can be lifted and planted out.
The sowing propagation method for the fringed iris is usually carried out when the top of the fringed iris capsule is ripe and splits open; collect the seeds and sow them immediately, and they sprout the same year. Using refrigerated seeds to break the dormancy of the fringed iris, they germinate 10 days after sowing. Seedlings of the fringed iris take 3-4 years to bloom.
An introduction to the propagation methods of the fringed iris, along with its pest and disease control methods
The fringed iris has rich flower colors and many varieties, and it is increasingly loved by flower enthusiasts. The flowers of the fringed iris are very large and very beautiful when in bloom. The fringed iris is very suitable for keeping at home and is a very good flowering ornamental plant. Today I, the editor, will join everyone in learning about the propagation and pest and disease control of the fringed iris.
Common diseases
1. Bacterial soft rot
Symptoms
It is mainly caused by bacteria of the genus Erwinia, leading to rot of the tissues or organs of the fringed iris; it mainly harms the plant's organs, tubers and stem base, among others. During the outbreak period the damage is severe; soft rot caused by bacteria usually produces a foul odor because miscellaneous bacteria break down protein gum and produce indole.
Control methods
1. Disinfect the seedlings.
2. The growing pots and tools must be disinfected.
3. The cultivation method must be appropriate.
4. Use drugs for prevention. Agricultural streptomycin, chloramphenicol and other antibacterial drugs can be used; the concentration does not need to be very high.
2. Leaf blight
Symptoms
July to October each year is the peak period for fringed iris leaf blight, and the plant's leaves are quite severely affected. Leaf blight overwinters on the diseased leaves of the fringed iris, and when the temperature is suitable the following year, it spreads to the fringed iris via wind and rain and causes infection.
Control methods
1. In autumn, thoroughly remove the diseased leaves and burn them in a concentrated way to prevent harm to the fringed iris the following year.
2. Strengthen the cultivation management of the fringed iris to control the occurrence of the disease.
3. In areas where the disease is relatively severe during the growing season, spray once every ten days; several consecutive sprays can effectively control it.
Common insect pests
They are often caused by the larvae of the noctuid moth, snails and slugs feeding on them. They generally harm the roots of the fringed iris from June to August each year, and unfinished organic fertilizer often attracts adults to lay eggs.
Control methods
They can be sprayed and killed with a 1000-fold dilution of 40% omethoate emulsifiable concentrate. Alternatively, spray and kill them with 3% lime water in the evening.
The above are the common pests and diseases of the fringed iris that I have compiled, along with their control methods. I hope they can be helpful to the many flower enthusiasts, and please continue to follow Duorou Huapu to learn more about flower care.
An introduction to the cultivation methods for keeping the fringed iris at home, along with points to note during cultivation
The fringed iris has rich flower colors and many varieties, and it is increasingly loved by flower enthusiasts. The flowers of the fringed iris are very large and very beautiful when in bloom. The fringed iris is very suitable for keeping at home and is a very good flowering ornamental plant. Today I, the editor, will join everyone in learning about the cultivation methods of the fringed iris.
Cultivation methods
1. Soil
The fringed iris likes moist, well-drained, humus-rich, slightly alkaline clay soil.
2. Watering
After planting the fringed iris, water once thoroughly, and afterward replenish water according to the actual dry and wet condition of the soil. For open-ground cultivation of the fringed iris, water once a week during the growing season; as the temperature drops, gradually reduce the amount of watering. Generally it is best to keep the soil slightly on the dry side; do not let the soil become waterlogged or stay overly wet for a long time, to avoid root rot or disease.
3. Sunlight
The fringed iris likes sufficient sunlight and is also slightly tolerant of shade. It is suitable for pot cultivation and can also be grown in the open ground. It has strong adaptability, and generally vigorous growth can be achieved with normal management.
4. Fertilizing
Before planting the fringed iris, apply a base fertilizer. From spring sprouting and growth until before flowering, the fringed iris should be given 1-2 applications of well-rotted dilute cake fertilizer water or compound flower fertilizer; after the flowers fade, it is best to apply 1 more application of liquid fertilizer.
5. Temperature
The suitable cultivation temperature is 25-28°C during the day. The temperature seen is also 18-20°C; at night the seedlings should be raised to about 23°C. In such a temperature environment, the fringed iris is almost in a growing state all year round, especially the seedlings grow rapidly; seedlings moved out of test tubes can bloom in about 1-2 years.
6. Humidity
The native habitat of the fringed iris has relatively high humidity, so to grow the fringed iris well, an environment with high air humidity must be created. Generally speaking, the humidity should be maintained at 60-80% all year round. In the vast northern regions, the climate is dry in spring, autumn and winter, so efforts must be made to increase the air humidity of the cultivation environment; this can be done by sprinkling water on the ground, benches, walls and other places several times a day, or by lightly moistening the plant leaves to increase the humidity of the local environment.
7. Light
When cultivating the fringed iris, be sure to remember strong light exposure; there should be good shading conditions. Although the leaves of the fringed iris are broad and thick and store abundant water, the cuticle layer and drought-resistant structures on the leaf surface are relatively poor, so once exposed to direct sunlight, more water is lost, or if it is not replenished in time, the leaves are very prone to sunscald.
8. Pests and diseases
Common diseases of the fringed iris include rust and soft rot. In the early stage of rust, a 400-fold dilution of 25% triadimefon can be used for control; for soft rot, a 1:1:100 Bordeaux mixture can be used for control. The insect pests of the fringed iris include the noctuid moth, which can be controlled by drenching the roots with a 1200-fold dilution of 90% trichlorfon.
Points to note
1. In North China, winter and spring are often sunny with few overcast and rainy days, so appropriate shading is needed at this time.
2. When the summer sunlight is strong and the temperature is too high, shade nets or bamboo blinds should be placed outside the greenhouse glass, serving the dual purpose of cooling the greenhouse and providing shade; the shading rate should be above 60%. In autumn, only about 40% shading is needed.
The above are the cultivation methods and points to note for the fringed iris that I have compiled. I hope they can be helpful to the many flower enthusiasts, and please continue to follow Duorou Huapu to learn more about flower care.
