How many years can Viola grow
The Viola blooming on the windowsill always brings the breath of spring, but do you know that this delicate-looking flower is actually a perennial plant? Mastering the correct care methods can make it bloom for more than 2 years, becoming a permanent guest on the balcony. Today, starting from professional horticultural experience, we will analyze the key factors affecting the lifespan of Viola.
The three key factors determining the lifespan of Viola
Temperature control is the basis for survival
Viola can maintain the best metabolic state at the ideal temperature range of 10-15°C. Experimental data shows that when the night temperature is stable above 8°C, the survival rate of the plant increases by 67%. During the high summer temperatures, it is recommended to move it to a north-facing windowsill, and combining misting can effectively extend the growth cycle.
Light management determines the amount of flowering
4-6 hours of scattered light per day is most conducive to nutrient accumulation, and strong sunlight at noon needs to be filtered with a shading net. In autumn and winter, it can accept full sun, and when the light intensity is lower than 10,000 lux, it is necessary to supplement light in time to ensure normal photosynthesis of the leaves.
The art of nutrient supply
In the seedling stage, use 20-10-20 water-soluble fertilizer to promote root development, and switch to a 10-30-20 formula during the bud formation stage. Adding seaweed extract every month can enhance stress resistance, and combining decomposed sheep manure can improve soil structure, which is the secret of professional nurseries to extend the lifespan of Viola.
Advanced techniques to extend lifespan
Regularly pruning the withered flowers can reduce nutrient consumption and retain the vitality of the plant. Dividing the plant every two years can not only obtain new plants but also stimulate the regeneration of the mother plant. Using a siphon water supply system to keep the matrix moist but not waterlogged is the key to avoiding root rot.
With scientific care, Viola can achieve an ornamental period of over 3 years. Remember these key points: precise temperature control, reasonable lighting, and step-by-step fertilization. Start practicing now, and let your Viola break the lifespan record and become a legend in the circle of flower cultivation!
