How to care for violas after their blooming period
Let me tell you about how to care for violas after their blooming period and some knowledge about the minimum cold tolerance temperature of violas and other plants, with the following details:
Violas are herbaceous flowers with an extremely long blooming period, lasting from November to May of the following year. They produce a large number of flowers and can easily achieve a full pot effect. However, many flower enthusiasts find that their violas bloom sparsely. What should be done to make violas bloom profusely? Different environments require different care methods.
1. Low-temperature environments
Violas are relatively cold-tolerant and can withstand temperatures as low as -10 degrees Celsius in winter, so they can survive outdoors in most regions during the winter.
If violas are left outdoors in winter, the low temperature will slow their growth, resulting in fewer flowers and more natural branching. During the entire winter, it is recommended to apply a soybean cake fertilizer once every 10 days or use "Flower More 1" to promote new branch growth in violas.
As long as sufficient fertilizer and water are maintained during winter, violas will naturally produce many branches, and by spring, the plants will be full and lush. When violas start to produce flower buds in the spring, switch to "Flower More 2" or potassium phosphate fertilizer, applying once every 5-7 days to achieve the full pot effect easily.
2. Warm environments
If you are growing violas in a closed balcony, a heated room, or in the warmer southern regions during winter, the plants will grow more rapidly. In this case, I recommend you pay attention to promoting branching by pinching the tops.
In warm environments, violas will continue to bloom in winter. However, if the seedlings are small, it is recommended to remove the flowers and apply "Flower More 1" once every 7 days. When the branches reach about 6cm in length, pinch the top buds, and if there are flowers, pinch them along with the top to control blooming while maintaining sufficient fertilizer and water. After a couple of months of growth, the crown of the violas will naturally become full, and you can then switch to phosphorus-potassium fertilizer to promote flowering.
Violas have a long blooming period and require a lot of fertilizer. It is important to continue applying fertilizer during the blooming period; do not stop fertilizing. If fertilization is stopped during the blooming period, the flowers of violas will become smaller and smaller.
Also, it is necessary to note that after the violas finish blooming in the spring, they will produce seeds. It is recommended to trim the spent flowers in time to avoid seed production, which can consume nutrients and shorten the blooming period. In the later stages of blooming, seeds can be left for collection. Violas have good self-seeding properties, and many self-seeded viola seedlings often appear in the ground by autumn.
Finally, it is important to note that whether growing violas indoors or outdoors, they need plenty of sunlight. Herbaceous flowers generally prefer sunlight. Insufficient light can lead to leggy growth without flowering. If possible, it is best to maintain full sun.
The above information about how to care for violas after their blooming period and the minimum cold tolerance temperature of violas can be used as a reference for green plant enthusiasts.
