What are the methods of propagating African violets?

Seed propagation of African violets

Sowing time: Spring or autumn is fine. Greenhouse cultivation will have a higher germination rate if sown in September or October.

Soil: African violet seeds are very small, so the soil for sowing must be fine. There is no need to cover the seeds with soil after sowing, just flatten them.

Temperature: The suitable temperature for the growth of African violets is about 18-26℃, and it will germinate about 15-20 days after sowing.

Humidity: The soil should not be too dry or too wet during the seedling stage. It is best to keep the soil moist.

Cutting propagation of African violets: mainly using leaf cuttings.

1. After flowering, select healthy leaves, cut off the petiole with a 2 cm length, leave it for a few minutes, and insert it into the sand bed after the cut is fully dried.

2. The roots will grow 3 weeks after planting, and seedlings will appear in 2 to 3 months and can be moved into a 6 cm pot.

3. During the cutting process, you can use liquid dissolved with vitamin B to water it to promote rooting.

PS: It usually takes 4 to 6 months for African violets to bloom from cuttings, but if it is done by cuttings from suckers, the effect is also very good and does not take long.

When African violets are propagated by cuttings, generally if they are taken in June or July, they will bloom in October-November. If they are taken in September or October, they will bloom in March-April of the following year.

Tissue Culture Propagation of African Viola

1. Take healthy African violet leaves and add 1 mg/L 6-benzylaminopurine and 1 mg/L naphthylacetic acid to MS medium.

2. Adventitious buds will appear 4 weeks after inoculation, and the rooted plantlets can be transplanted 3 months later.

3. The survival rate is higher when transplanted in a substrate composed of half leaf mold and half peat moss soil.

Key points for cultivation of African violets:

1. Repotting: When the seedlings have 3-4 leaves, transplant them into a 6cm pot. When they have 7-8 leaves, transplant them into a 10cm pot.

2. Watering: In spring, autumn and winter, the temperature is low, so water less. In summer, it is hot and dry, water more.

3. Light: African violets are semi-shade plants, and 8 hours of light a day is more suitable. Do not expose them to the sun in summer.

4. Fertilization: Fertilize once every half month during the growing season, and apply phosphorus and potassium fertilizers twice during the flowering period.
