Viola tricolor is a biennial or perennial herbaceous plant belonging to the Viola genus of the Violaceae family. It is a common wildflower species in Europe and the national flower of Iceland and Poland. Viola tricolor is mainly cultivated outdoors and is not suitable for indoor planting. The best time for planting Viola tricolor is in spring and autumn, preferably in September for autumn sowing. Prepare the seeds first, then plant them in the soil, maintaining a temperature between 18°C and 21°C, protecting them from direct sunlight, and they will germinate in about a week. Next, let's talk specifically about the sowing time and method for Viola tricolor.
1. Sowing Time
The sowing time for Viola tricolor can be in spring and autumn, preferably in September for autumn sowing. When sown in autumn, flowers will bloom in spring. The mild spring climate is conducive to the growth of the plants. It is essential to ensure the germination temperature for Viola tricolor, or it will affect the plant's growth.
2. Sowing Method
Prepare the seeds first, then deeply plant them in good quality soil, adjusting the temperature of the growing environment to between 18°C and 21°C. After sowing, avoid direct sunlight, and they will germinate in about a week.
3. Transplanting
When the seedlings have grown 4 small leaves, they can be transplanted, ensuring the roots are covered with soil. After the seedlings have emerged, the plants will require more water and light, and need to be transplanted into a larger pot. The key to germinating Viola tricolor seeds is to keep the potting soil moist at all times. After each watering, wrap the pot with plastic film. Find a warm and comfortable place to care for them, using fertile, loose soil rich in humus for planting, which is beneficial for plant growth.
4. Post-Transplant Care
After transplanting, the seedlings need plenty of sunlight. The growth temperature should be between 7°C and 15°C. Watering should not be too much or too little, as it may hinder plant growth. Fertilize appropriately in the early growth stage, mainly with nitrogen fertilizer, and during the flowering period, mainly with phosphorus fertilizer. Be sure to remove any dead branches and flowers from the plant, which can promote the growth of new branches and more flowers.
5. Disease Prevention and Control
Common diseases of Viola tricolor include scab disease and mosaic virus. Scab disease mainly affects the leaves of the plant, causing brown spots on the infected leaves. The key to preventing scab disease is to avoid overwatering and maintain good ventilation. If the disease is detected, isolate the infected plants. You can choose to spray an 18% copper oxychloride wettable powder 200 times solution or a 75% chlorothalonil 800-1000 times solution for control.
