How to hydroponically grow viola flowers
Hydroponically cultivating violas not only maintains their fresh and elegant appearance but also extends their blooming period for appreciation. Mastering the correct care methods can keep violas blooming in water for 2-3 months. This article will systematically explain the complete process of hydroponically growing violas, from plant treatment to daily care, making your flower care more efficient and effective.
Basic preparation for hydroponically growing violas
Plant cleaning and treatment
Select a robust potted plant with glossy leaves, and water it thoroughly 72 hours in advance. Gently tap the pot walls when removing the plant to fully extract the roots and then rinse them with running water. Retain the main root mass, trim the blackened and decayed roots, and keep 3-5 cm of new white roots for better hydroponics.
Key steps in hydroponic cultivation of violas
Container selection criteria
It is recommended to use transparent glass containers with a height of 15-20 cm. The diameter of the container should allow the roots to spread out, with the water level controlled at 2/3 of the roots. It is suggested to use spring water or mineral water, and tap water should be left to stand for 48 hours to remove chlorine, with the water temperature maintained at 18-22℃ for optimal conditions.
Usage specifications for nutrient solution
Add a special hydroponic nutrient solution when changing the water weekly, diluted at a ratio of 1:500. Increase to twice a week in spring and summer, and once a month in autumn and winter. Be especially careful to avoid contact between the nutrient solution and the leaves, and gently shake the container after adding to evenly distribute the solution.

Seasonal care points
In summer, replenish the evaporated water daily, move the container to a cool and well-ventilated place, and place ice packs to cool the water when it exceeds 28℃. In winter, maintain a room temperature above 10℃, changing the water once a month. In spring and autumn, the plant can receive soft light in the morning and evening, with shading required at noon to prevent sudden rises in water temperature.
Disease prevention measures
Immediately cut off the decayed parts when the roots become sticky and soak them in a 0.1% potassium permanganate solution for 10 minutes. If yellow spots appear on the leaves, spray them with carbendazim solution twice a week for three consecutive weeks. Regularly clean the inner walls of the container with a soft brush to prevent the growth of algae.
Through scientific hydroponic management, violas can maintain a 60-90 day viewing period. Pay attention to the plant's condition, adjust the water level and nutrient supply in a timely manner, and rotate the container regularly to ensure even exposure to light. Master these care secrets, and you can also easily create a vibrant hydroponic viola landscape.
