A Detailed Guide to Growing Viola cornuta, Sharing the Latest Cultivation Tips

Viola cornuta is a flower commonly seen in urban landscaping. It originated in Europe, and its small blooms in a wide range of colors make it a very charming flower. Many people who have seen Viola cornuta hope to grow such a beautiful flower at home. Today, Qinnong Net will introduce the growing method for Viola cornuta.

When it comes to growing methods, we still have to start with the most basic aspects: sunlight, temperature, water, soil and fertilizing. These topics may sound like the same old story, but every plant has different characteristics and different requirements for these points, so to grow a plant well you must still start from these aspects. Let us take a closer look below:

1. Light

Qinnong Net mentioned above that Viola cornuta originated in Europe. Because of the higher latitude, the light there is not strong, so Viola cornuta itself is not as sensitive to light as tropical and subtropical flowers, and growing in a shady place does not affect its growth too much. But Viola cornuta still very much likes sunlight. Giving it more light normally will make it grow more branches.

2. Soil

The soil most suitable for Viola cornuta to live in is a slightly acidic soil with a pH value between 5.5 and 6.5. The soil needs good drainage and more organic matter. When sowing, you can use a 1:1 mix of peat and perlite. The soil must be kept moist.

3. Temperature

Because Viola cornuta originated in the high-latitude regions of Europe, where the temperature is lower, this also determines its cold tolerance, and it can even tolerate light frost. Viola cornuta in warm regions such as the south can make it through a winter. Viola cornuta cannot be grown in places with too high a temperature. 10 degrees to 15 degrees is the best temperature, and above 30 degrees it cannot grow normally.

4. Water

Also because of the environment of its place of origin, Viola cornuta usually grows in a cool and shady environment where little water is lost, so it does not need too much watering. During the flowering period you will find that the water demand of Viola cornuta rises sharply. On one hand, the temperature begins to rise at this time and water evaporation increases; on the other hand, flowering needs energy, so the water consumption of Viola cornuta becomes greater. Especially after the Spring Festival, when the temperature rises to degrees, basically watering once a day is needed to ensure the energy required for flowering.

5. Fertilizing

I forgot to mention earlier that Viola cornuta is usually grown by sowing. Once the seedlings grow tender leaves, you can begin fertilizing. First use 50 to 75 ppm nitrogen fertilizer, then gradually increase the concentration to 100 ppm. You should also properly supplement potassium fertilizer, with the two in a 1:1.5 ratio. You should also spray a trace element solution to supplement iron and magnesium.

6. Pest and Disease Control

Viola cornuta may be damaged by pests such as aphids, red spider mites and thrips. You should pay attention to the cleanliness of the growing environment and not plant it in places where there are pests. Common diseases include leaf ring spot and downy mildew. Controlling the soil pH value can also reduce the probability of Viola cornuta getting sick.

The above is the basic care method for Viola cornuta introduced by Qinnong Net. Keep in mind that Viola cornuta is a flower from Europe, and its growing environment is different from ours. Especially in southern regions, during the high-temperature summer season you should pay attention to cooling it down and place Viola cornuta in a ventilated, cool place, so as to help it grow healthily.
