Bougainvillea Blooming Time
Bougainvillea, a common ornamental plant in southern courtyards, has become a star variety in the gardening world with its extremely long blooming period. From late spring to early winter, the eight-month blooming period makes this plant highly favored. However, scientific maintenance methods are particularly important to keep it blooming continuously.
Bougainvillea Blooming Cycle Characteristics
Geographical Environment Impact
In subtropical regions, bougainvillea begins to sprout flower buds in mid-April and can still be seen blooming sporadically in November. In the northern regions, due to temperature differences, the blooming period is usually shortened to May to October. With greenhouse cultivation and artificial control, it is possible to achieve blooming throughout the year.
Variety Differences
Different varieties have significant differences in blooming periods: the green leaf red variety can bloom for up to 280 days, while the California gold variety shows intermittent blooming characteristics. Choosing a diligent flowering variety combined with scientific maintenance can maximize the extension of the viewing period.
Key Points of Bougainvillea Post-Blooming Management
Pruning and Shaping Techniques
Immediately after blooming, remove the spent flowers and dense branches, retaining 3-4 buds on the main branches. Use a 45-degree oblique cutting method for the cuts, combined with wound healing agents to prevent infection. Focus on cleaning the crossed branches inside the plant to ensure good ventilation and light penetration.
Light Control Plan
After blooming, ensure 6 hours of direct sunlight per day, and provide appropriate shading at noon in summer. Regularly rotate the pot to ensure even light exposure, and use supplemental lights for 2 hours daily when there is insufficient light to prevent the branches from becoming elongated.
Water and Fertilizer Management Strategy
Adopt the principle of "frequent application of thin fertilizer", alternating the application of phosphorus and potassium fertilizer with organic liquid fertilizer every 10 days. It is recommended to use fermented orange peel water (dilution ratio 1:50) combined with potassium dihydrogen phosphate solution (concentration 0.2%), and keep the watering in a "dry and wet" state, with moisturizing sprays in the morning and evening in summer.
Ensuring Continuous Blooming of Bougainvillea
Regularly check the root condition and change the acidic humus soil every 2 years. Maintain a temperature above 12℃ in winter, combined with a monthly supply of trace elements. Through systematic management, it is possible to achieve alternating blooming of new and old branches, creating a landscape effect with flowers all year round.
