Violas, which belong to the Viola genus, can indeed survive indoors. While many species in this genus are technically annuals, they have a tendency to reseed themselves so readily that they may as well be considered perennials. This makes them excellent candidates for indoor cultivation, as they can be easily propagated and maintained throughout the winter months.
To successfully grow violas indoors, it is important to ensure that they receive adequate sunlight. Place your potted violas in a location that receives bright, indirect light for at least six to eight hours a day. If natural light is limited, you can supplement it with artificial grow lights. Position the lights about six to twelve inches above the plants and keep them on for about 12-16 hours each day.
In terms of temperature, violas prefer cool conditions, ideally between 60-70°F (15-21°C). They can tolerate slightly lower temperatures, but avoid exposing them to extreme cold or heat. Maintaining a moderate temperature will help promote healthy growth and prevent wilting or damage to the plants.
When it comes to watering, it’s important to strike a balance. Violas prefer evenly moist soil, but they don’t like to sit in waterlogged conditions. Allow the top inch of soil to dry out slightly before watering again. To prevent overwatering, check the moisture level by inserting your finger into the soil. If it feels dry, it’s time to water. However, if it feels damp, hold off on watering for a little longer.
Fertilizing your indoor violas is also crucial for their long-term survival. Use a balanced, water-soluble fertilizer with equal nitrogen (N), phosphorus (P), and potassium (K) ratios. Dilute the fertilizer according to the package instructions and apply it to the soil every two to four weeks during the growing season. This will provide the necessary nutrients for healthy foliage and continuous blooming.
One of the keys to keeping your violas going for multiple seasons is allowing the flowers to go to seed. Violas are self-pollinating, which means they can fertilize themselves and produce seeds without the need for external pollinators. Once the flowers have withered, you can gently shake or tap the plant to release the seeds. Collect the seeds and store them in a cool, dry place for future sowing. Alternatively, you can allow the seeds to fall naturally into the potting soil, where they may germinate and give rise to new plants.
To maintain the overall health and appearance of your violas, regular grooming is essential. Remove any dead or yellowing leaves, spent flowers, or damaged parts of the plant. This will not only improve the aesthetic appeal but also prevent the spread of diseases or pests.
Violas can thrive indoors and be treated as perennial plants if provided with adequate light, cool temperatures, proper watering, and regular fertilization. By allowing the flowers to go to seed and collecting those seeds, you can continue to propagate and enjoy these charming flowers for multiple seasons. So go ahead and bring the beauty of violas indoors, adding a touch of color and cheer to your home throughout the year.
