How to grow Viola mandshurica seeds

1. Sowing Viola mandshurica

Before sowing, the soil should be disinfected to achieve the purpose of cultivating strong seedlings and preventing seedling-stage pests and diseases. After sowing the seeds, cover them with fine soil passed through a fine sieve, and the covering thickness should be such that the seeds are not visible. Sowing time: spring sowing in the first and middle ten days of March. Autumn sowing in the first ten days of August. After sowing, control the temperature between 15°C and 25°C, and seedlings will emerge in about one week.

2. Division propagation of Viola mandshurica

First, plow the landscaping land, apply sufficient base fertilizer, and level it. When using the division method for propagation, the effect is relatively quick. Under the same conditions, when transplanting by division, small Viola mandshurica plants recover from transplanting faster than larger plants, have a higher survival rate, and have a longer green period.

3. Natural reproduction of Viola mandshurica

Viola mandshurica has a very strong ability to self-reproduce. Let it scatter with the wind and reproduce naturally.

4. Seedling-stage management of Viola mandshurica

After the small seedlings have all emerged, management should be strengthened. In particular, temperature should be controlled to prevent the small seedlings from growing leggy. At this time, light should be sufficient, the temperature should be controlled at 15°C during the day and 8°C to 10°C at night, and the soil should be kept slightly dry.

5. Growing-period management of Viola mandshurica

Viola mandshurica grows robustly and has strong resistance. During the growing period, no special management is needed. During its peak growing season, apply organic fertilizer once every 7 to 10 d, which will make its landscape effect even better. During the growing period, pay attention to pulling out weeds. Generally, no topdressing is applied, and attention should be paid to drainage during the rainy season.

6. Harvesting Viola mandshurica seeds

When the seeds of Viola mandshurica mature and dry, they will crack rapidly and eject the seeds. Therefore, they should be harvested after the capsules stand upright and before the seeds have cracked. During the process of drying the seeds, take care to cover the capsules well with window screen to prevent the seeds from being ejected. Then sieve them and store the seeds dry.

Planting methods for Viola mandshurica

1. If growing at home, you can prepare culture soil for raising seedlings. For the soil mix, it is best to use garden soil plus leaf mold and fine sand mixed together in a ratio of 2:2:1, and then disinfect it. Disinfected soil can avoid the threat of seedling-stage pests and diseases.

2. Store the collected seeds in a ventilated and dry place. Choose to sow them in December of winter in a greenhouse with a temperature of 2 to 8 degrees. In the second year, the seeds will grow into seedlings, and by March they can be moved into larger pots. You can also collect seeds in May and sow them immediately, so they will sprout very quickly.

3. After sowing, the temperature indoors must be maintained at 15 to 25 degrees.

4. After the small seedlings have grown out, the temperature should be specially controlled to prevent the small seedlings from growing leggy. Also at this time, attention should be paid to supplementing light sufficiently. The daytime temperature should be 15 degrees, the nighttime temperature should be 8 to 10 degrees, and the soil should be kept slightly dry.

5. When the small seedlings grow their first leaf, they can be separated and planted. The water underneath should be thoroughly moistened. At this time, the temperature can be maintained at 20 degrees during the day and about 15 degrees at night. A little fully decomposed organic fertilizer can also be appropriately applied to the soil to promote its growth.

6. When the seedlings grow 5 leaves, they can be planted in their final position, and the space between every 40 plants should reach 1 sq m.

Precautions for cultivation

1. This plant is prone to infection by fungi imperfecti and then leaf spot disease. If not treated in time, it will cause large black spots, and then the leaves will gradually wither and fall. So once it becomes diseased, prepare a medicinal solution and spray the leaf surface.

2. Because this plant has very strong resistance, no special management is needed during its growth period. However, in the season when it grows more vigorously, you can apply organic fertilizer once every 7 to 10 days.

3. This plant easily attracts red spiders that damage the leaves. Lime sulfur mixture can be prepared to spray and kill the red spiders.

Growth habits of Viola mandshurica

It likes light and prefers a moist environment. It is shade-tolerant and also cold-tolerant. It is not selective about soil, has extremely strong adaptability, and is easy to propagate. It can be directly sown. It generally begins to sprout in the first ten days of March. The flowering period is from the middle ten days of March to the middle ten days of May. The full flowering period lasts about 25 days. A single flower continues to bloom for 6 days, and it takes 30 days from flowering to seed maturity. From April to the middle ten days of May, there are a large number of cleistogamous flowers that can form a large number of seeds. In the last ten days of September, a small number of flowers appear again.

As described above, the sowing method of Viola mandshurica is relatively simple, and the flowers of Viola mandshurica are purple, small and delicate, and are deeply loved by everyone.
