A Detailed Guide to the Planting Methods and Steps for Viola cornuta

Viola cornuta is a flower commonly seen in urban landscaping. It originates from Europe, and its small, colorful blooms make it a very lovely flower. Many people who have seen Viola cornuta hope to grow such a beautiful flower at home, so today Qinnong Web will introduce the planting method for Viola cornuta.

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

I. Light

As Qinnong Web mentioned above, Viola cornuta originates from Europe. Because of the higher latitude and weaker light there, Viola cornuta itself is not as sensitive to light as tropical and subtropical flowers, and growing in shade does not affect its growth too much. But Viola cornuta still likes sunlight very much. Giving it more light normally will make it grow more branches.

II. Soil

The soil more suitable for Viola cornuta to live in is slightly acidic soil with a pH between 5.5 and 6.5. The soil needs good drainage and more organic matter. When sowing, peat and perlite can be mixed at 1:1. The soil should be kept moist.

III. Temperature

Because Viola cornuta originates from the high-latitude regions of Europe, where the temperature is lower, this also determines its cold-resistant trait, 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°C to 15°C is the best temperature, and above 30°C it cannot grow normally.

IV. Water

Also because of the environment of its place of origin, Viola cornuta usually grows in a cool environment where less water is lost, so it does not need to be watered too much. During flowering, you will find that the water demand of Viola cornuta rises sharply. On one hand, the temperature begins to rise at this time and 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 ten or twenty degrees, watering basically once a day is needed to ensure the energy required for flowering.

V. Fertilizing

Earlier I forgot to mention that Viola cornuta is usually grown by sowing. After the seedlings grow tender leaves, fertilizing can begin. First use 50 to 75 ppm nitrogen fertilizer, then gradually increase the concentration to 100 ppm. Potassium fertilizer should also be supplemented appropriately, with the two at a ratio of 1:1.5. A trace element solution should also be sprayed to supplement iron and magnesium.

VI. Pest and Disease Control

Viola cornuta may be damaged by pests such as aphids, red spiders and thrips. Attention should be paid to the cleanliness of the cultivation environment, and it should not be planted in places with pests. Common diseases include leaf ring spot and downy mildew. Controlling the soil pH can also reduce the probability of Viola cornuta getting sick.

The above is the basic care method for Viola cornuta introduced by Qinnong Web. 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, attention should be paid to cooling, and Viola cornuta should be placed in a ventilated and cool place. Only in this way can it grow healthily.
