Lavender flowering period in which month
Whenever the purple sea of flowers covers the valley, there are always people curious about the secrets of the flowering period of this romantic plant. As a star in the aromatic plant world, the flowering period and maintenance skills of lavender have always been the focus of gardening enthusiasts.
Analysis of the core rules of lavender flowering period
Characteristics of natural flowering period
The flowering period of typical lavender varieties is concentrated in June and July, early flowering varieties begin to bud in late May, and late flowering varieties can last until early October. In the Mediterranean climate area, the peak flowering period of plants is about 45 days, while in high-latitude areas such as Yili, the flowering period is extended to 60 days due to the large temperature difference between day and night.
Geographical climate influence map
The environment with a temperature of 20-28℃ and an annual sunshine duration of more than 2000 hours is most suitable for flowering. The flowering period in the Yunnan-Guizhou Plateau is 15 days earlier than that in the North China Plain, and rainproof shelters need to be built in the Jiangnan region due to the plum rain season.

Selection of special varieties
Lavandula pinnata, through genetic improvement, achieves annual flowering and requires a constant temperature environment of 15-30℃. Hybrid varieties such as Spanish Eye can bloom three times a year under greenhouse conditions.
Continuous flowering regulation technology
Using a supplementary lighting system to extend the lighting time to 14 hours/day, combined with foliar application of potassium dihydrogen phosphate (0.2% concentration) every week. After pruning the residual flowers, apply organic fertilizer to shorten the cycle of new branch germination to 20 days.
Three practical strategies for extending the flowering period
Light management plan
In spring and autumn, full-day sunshine care is recommended, while in summer, a shading rate of 30% is optimal. For indoor cultivation, configure full-spectrum plant lights and maintain a light intensity of 20000Lux at a distance of 40cm from the plants.
Precise fertilization system
Apply high-phosphorus water-soluble fertilizer (N-P-K=10-50-10) during the bud formation period, and supplement controlled-release fertilizer after the flowering period. The annual fertilization amount per square meter is controlled at 15g nitrogen, 20g phosphorus, and 25g potassium.
Temperature and humidity control parameters
Set a day and night temperature difference of 8-10℃ to stimulate flower bud differentiation, and maintain the air humidity between 40-60%. Install an automatic spray system, and spray for 30 seconds every 2 hours during high temperatures.
Mastering these key technologies, even gardening beginners can successfully create a lavender garden that is fragrant throughout the year. From variety selection to environmental regulation, precise control of each link is the key to extending the flowering period.
