How do you propagate African violets? Leaf cuttings are the most practical method
When it comes to African violets, gardening enthusiasts are certainly familiar with them. They are an ornamental flower with a great many varieties and rich colors, deeply loved by flower lovers. In daily life, many people want to grow African violets, but buying them to grow is not as good as planting them yourself, and this requires us to master the propagation methods of African violets. So how do you propagate African violets? Today the editor will give you a detailed introduction.
I. How to propagate African violets
When it comes to propagating African violets, there are usually three methods: leaf cuttings, sowing, and tissue culture propagation. Among them, leaf cuttings are the most practical: insert the leaves of the African violet into the growing medium, and once they root, move them into pots to grow. Sowing means scattering African violet seeds onto the soil and moving the seedlings once they sprout. Tissue culture is rather troublesome; just knowing about it is enough.
II. Propagation methods of African violets
(1) African violet leaf cutting propagation method
1. Cutting time
The most commonly used method for African violets is cutting propagation, of which leaf cuttings are the main type. The best time for cuttings is spring and autumn, because in an environment of 18-24°C, its rooting rate is higher.
2. Selection of cuttings
For African violet leaf cuttings, the most important thing is choosing the cuttings. After the African violet's flowering period has passed, choose healthy, plump leaves, leave 2 cm at the petiole, and cut off the rest to use as the cutting.
3. Cutting medium
Because these are African violet leaf cuttings with no roots, they cannot absorb water, so the cutting medium should not contain too much moisture. It is best to use a medium with good aeration, such as perlite and vermiculite.
4. Starting the cuttings
Let the cut leaves dry slightly, then insert them into the prepared medium, and afterward maintain relatively high air humidity. Generally, roots will form 3 weeks after insertion, and seedlings will be produced in 2-3 months. At that point, move them into 6 cm pots and care for them according to African violet cultivation methods.
(2) African violet sowing propagation method
Besides cuttings, the most commonly used propagation method for African violets is sowing, and the best time is September-October, when the germination rate is high. Sowing method: scatter the African violet seeds onto the potting soil, do not cover with soil after sowing, just press flat. Generally, they will sprout in 15-20 days, and the seedlings can be moved after 2-3 months.
(3) African violet tissue culture propagation method
How do you propagate African violets? You can also use the tissue culture method. Method: use African violet leaves, petioles, and epidermal tissue as explants, culture them with MS medium plus 1 mg/L 6-benzylaminopurine and 1 mg/L naphthaleneacetic acid. After 4 weeks, adventitious buds will grow, and after 3 months, the rooted plantlets can be planted.
Overall, whether it is leaf cuttings, sowing, or tissue culture, African violets can survive, but the most suitable for indoor propagation is still leaf cuttings. Of course, methods are fixed while people are flexible; you can choose a method to propagate according to the actual situation. That is all the editor has to introduce about African violet propagation methods, and I hope it can be of help to everyone.
How to propagate African violets: propagation methods for African violets
African violets are a type of flower. African violets are a flower that people relatively like to use to decorate and beautify the environment. How do you propagate African violets? Let us take a look together at the propagation methods of African violets below.
1. African violet leaf cutting propagation method
African violets commonly use the cutting propagation method, mainly leaf cuttings. After flowering, choose robust, plump leaves, cut them off leaving a 2 cm long petiole, let them dry slightly, insert them into a sand bed, and maintain relatively high air humidity at a room temperature of 18-24°C. They will root 3 weeks after insertion, produce seedlings in 2-3 months, and then be moved into 6 cm pots. During the cutting process, treatment with vitamin B is beneficial to the growth of seedlings after African violets root. Treating the petioles with 25 mg/L kinetin for 24 hours is beneficial to the formation of adventitious buds. From cutting to flowering takes 4-6 months.
2. African violet stem cutting propagation method
The stem cutting propagation method is also a propagation method chosen for African violets, mainly after the flowers fade in spring. Combined with repotting and changing the soil, divide the underground tubers and plant them. Seedlings form quickly, but the plant shape is not attractive enough, and because the plant has not been renewed, growth is not vigorous enough.
3. African violet tissue culture propagation method
The propagation method that is relatively popular for African violets now is tissue culture propagation, using leaves, petioles, and epidermal tissue as explants. Use MS medium plus 1 mg/L 6-benzylaminopurine and 1 mg/L naphthaleneacetic acid. After inoculation, adventitious buds grow in 4 weeks, and after 3 months the rooted plantlets can be planted. The plantlets are transplanted into a substrate of half leaf mold and half peat moss soil, with a 100% survival rate. At present, the United States, the Netherlands, Israel and other countries all have African violet test-tube plantlet production. However, this method produces relatively many plantlets and is not very suitable for home cultivation.
4. African violet sowing propagation method
African violet sowing propagation can be carried out in spring and autumn. For greenhouse cultivation, autumn sowing in September-October is better, with a high germination rate, and the seedlings grow robustly, flowering in the following spring with large plants and many flowers. Sowing in February means flowering in August, but the growth vigor is slightly poorer and there are fewer flowers. African violet seeds are tiny, so the sowing potting soil should be fine. Do not cover with soil after sowing, just press flat. The suitable germination temperature is 18-24°C. They sprout 15-20 days after sowing, and seedlings are moved after 2-3 months. During the seedling stage, note that the potting soil should not be too wet. Generally, from sowing to flowering takes 6-8 months.
How to propagate African violets? Propagation methods for African violets
African violets are a common indoor potted plant. They have rich, gorgeous colors and also have effects such as purifying indoor air, improving air quality, and soothing the mood, making them deeply favored by flower and plant lovers. In the process of potting African violets, I believe everyone is most concerned about the issue of propagation. So, how do you propagate African violets? The propagation methods of African violets are introduced below.
