Viola cornuta care

The cultivation of purple viola is very simple, from the sowing of seeds at the end of summer. Its location in the garden will be in full sun and the soil must be rich in organic matter.

DIY gardeners often purchase packets of horticultural and ornamental seeds to grow. Knowing or having technical expertise in this area helps a lot. In this context, we present relevant technical data on the cultivation of Viola cornuta. These data should always be used as a guide, as it depends on the crop, substrate used, climate, etc. Results can vary widely.

As plants in the group of seasonal ornamentals and autumn plants, we plant them in pots with a diameter of about 10 cm after the seedlings have germinated. Once they have grown to a reasonable size, we can plant them directly in the garden.

The substrate indicated in this case is a universal substrate or substrate for outdoor plants with a pH between 5,8 and 6. The required Ec (substrate conductivity) must be between 1 and 1,5. The ideal temperatures are between 2 to 5ºC at night and 20 to 22ºC during the day. Below them, their development will slow down, above them, they will speed up, and in no case will their growth be ideal.

The exposure of the newly planted plants will be done in full sun, since the climate is not very hot at this time of the year when Viola is planted. The risk will be moderate, with frequent occurrences during the first week, keeping them at a distance during the rest of the crop to favor root development.

Fertilization can be done 4 or 5 weeks after planting with fertilizer 18-12-24 (mixed in irrigation water) at a dose of 1 gram per liter twice a week. The most common pests are aphids and caterpillars.

As for diseases, they are not very frequent, but in case of risk, Alternaria, Tielaviopsis and Cercospora are probably the most prone. In these conditions, violas take 8-12 weeks to grow from pruning (planted in pots) until ready for direct sowing in the garden.

Viola cornuta is characterized by seed propagation, especially during the months called spring or summer. All you have to do is put them in a glass with water and after a few minutes, only sunken seeds will be removed.

They must then be placed on a substrate with a distance between them, which has previously been moistened and can be easily placed in pots or seedling trays. Subsequently, they are covered with more substrate, watered and placed in direct sun if it is spring, or in a shady place if it is summer. They usually germinate in less than two weeks. During this time, it is important to verify that the substrate is completely wet.
