When does lavender bloom?
Every midsummer, the purple sea of Provence always stirs curiosity about the blooming period of lavender. This plant, hailed as the "Queen of Aromas," holds unique natural codes within its blooming patterns and cultivation techniques. This article will delve into the complete cycle of lavender from sprouting to full bloom, guiding you to master the core secrets of extending the flowering period.
Analysis of Lavender's Natural Blooming Period
Geographical Climate Influence
The typical blooming period集中在6-8月, but latitude differences significantly affect the blooming time: flower buds appear in early June in North China, mid-May in the Jiangnan region, and can last until late September in the Yunnan-Guizhou Plateau. A day-night temperature difference of 8-12℃ is most conducive to flower bud differentiation.
Variety Characteristics Difference
Narrow-leaf lavender (Lavandula angustifolia) has the longest blooming period, which can last up to 120 days, while the toothed leaf variety only lasts 45-60 days. In recent years, hybrid varieties such as "Blue Star" and " Hidcote" have extended the viewing period by 30%.
Extended Blooming Care System
Three Elements of Light and Temperature Control
① Daily sunlight needs to reach 6-8 hours, and shading is required when UV intensity > 3. ② Ideal growth temperature range: day temperature 22-28℃/night temperature 15-18℃. ③ Maintain a temperature difference of over 10℃ during the flower bud differentiation period.
Precise Water and Fertilizer Management
Adopt the "dry-wet cycle" irrigation method: water thoroughly when the topsoil 3cm is dry, and spray with potassium dihydrogen phosphate (0.2% concentration) every half month. Applying boron and zinc micro-fertilizers during the budding stage can increase flower density by 30%.
Pruning Techniques to Promote Flowering
Remove the残花 immediately after flowering, leaving the second pair of leaves, and combined with pinching the top can stimulate a second flowering. Be sure to retain the main stem 8-12cm to ensure the plant stores energy for winter.
Through a scientific care system, potted lavender can bloom 2-3 times a year, with the longest flowering period of a single plant reaching up to 150 days. Mastering these natural laws and horticultural techniques, you can also create a continuously blooming purple dreamland.
