How to raise bougainvillea
Bougainvillea is known as the "Southern Rose" because of its colorful colors. Mastering scientific maintenance methods can allow it to bloom all year round. This article systematically analyzes the entire process of Bougainvillea planting and teaches you hands-on how to create a flower wall landscape. Analysis of the core points of Bougainvillea maintenance Scientific water control and flower promotion skills Keep the soil slightly moist during the spring and autumn growth period, spray in the morning and evening in summer to increase humidity, and strictly control water to prevent root rot in winter. Implement the "dry-drying alternating method" during the bud appearing period: water is cut off for 3 consecutive days and then watered thoroughly, and repeat it 3 times can stimulate flower bud differentiation. Precise temperature control plan establishes temperature gradient management: 15-28℃ is the best growth range, above 35℃ requires shading and cooling, and below 5℃ requires indoor maintenance. Maintaining the temperature difference between day and night at around 8 ° C can prolong the flowering period. In winter, the heating environment needs to be used in conjunction with a humidifier. Precise nutrition supply strategy From April to July, long-term use of N-P-K=15-30-15 water-soluble fertilizer, combined with decomposed sheep manure as base fertilizer. Use potassium dihydrogen phosphate foliar fertilizer (diluted 1000 times) during the budding period, and spray it every 10 days until the flower buds develop color. The intelligent light adjustment plan implements stepped light management: light is scattered for 4 hours a day during the seedling period, and direct light is needed for 6 hours for adult plants. Use 50% sunshade net in summer and use full-spectrum fill light in winter to ensure that daily light time is ≥8 hours. For the advanced tutorial on Bougainvillea reproduction, semi-lignified branches are preferred and the "girdling method" is used: girdling 1cm from the top 15cm, and wrapping them with water moss to promote roots. The substrate is mixed with perlite: vermiculite =3:1, combined with rooting powder solution, and maintaining a constant temperature environment of 25℃, the survival rate can reach 90%.
Through systematic maintenance and management, bougainvillea can bloom all year round. It is recommended to establish a maintenance log to record temperature and humidity changes and plant responses, and gradually form a personalized maintenance plan. Regular pruning to maintain crown shape, combined with pest prevention, makes your bougainvillea a real "flowering machine."
