Cultivation methods and precautions of Viola yedoensis

one. Farming methods

1 If you are planting at home, you can prepare the culture soil for cultivating seedlings. The best soil mixture is to use garden soil, leaf mold and fine sand in a ratio of 2:2:1, and then disinfect it. Disinfected soil can avoid the threat of diseases and pests during the seedling stage.

2 Store the collected seeds in a ventilated and dry place, and choose to plant them in a greenhouse with a temperature of 2 to 8 degrees in December. In the second year, the seeds will sprout, and in March they can be moved to a larger pot. You can also collect seeds in May and sow them immediately so that they will germinate quickly.

3 After sowing, the temperature in the room must be maintained between 15 and 25 degrees.

4 After the seedlings have grown out, the temperature must be specially controlled to prevent them from growing too tall. At this time, you must ensure that there is sufficient light. The daytime temperature should be 15 degrees, and the night temperature should be between 8 and 10 degrees. The soil should be slightly dry.

5 When the seedlings grow the first leaf, you can start planting them separately, and the water underneath should be soaked. At this time, the temperature can be maintained at 20 degrees during the day and around 15 degrees at night. You can also apply some decomposed organic fertilizer to the soil to promote its growth.

6 When the seedlings grow 5 leaves, they can be positioned for planting. The space between every 40 plants should reach 1 square meter.

two. Attention to breeding

1Since this plant has very strong resistance, it does not require special management during its growth period. However, in its more vigorous growth season, organic fertilizer can be applied to it every 7 to 10 days.

2 This plant is prone to red spider mites attacking its leaves. You can prepare lime sulfur mixture to spray and kill the red spider mites.

3 This plant is easily infected by Aspergillus niger and then develops leaf spot disease. If not treated in time, it will cause large black spots, and the leaves will slowly turn yellow and wither. So once it gets sick, be prepared to spray the leaves with medicine.
