Techniques for Dwarfing Bougainvillea
The editor introduces you to the techniques for dwarfing bougainvillea and related topics about the dwarfing treatment methods of bougainvillea cultivation. Here is a comprehensive introduction.
Techniques for Dwarfing Bougainvillea
1. Water and fertilizer control. During the growth of bougainvillea, water and fertilizer are essential nutrients. Therefore, some conscious control can be applied to ensure that the nutrient supply is just right and it does not easily grow too tall, achieving the purpose of dwarfing.
2. Control through pinching. Pinching, also known as topping, is not only aimed at controlling the main stem's height but can also break its original apical dominance, allowing the lower parts to grow better.
3. Control through pruning. In March each year, remove all long and large branches, and also make repairs to diseased, weak, withered, and overlapping branches. This method not only dwarf the tree shape but also improves lighting and ventilation, making the bougainvillea healthier.
Precautions for Pruning Bougainvillea
1. Before pruning bougainvillea,消毒 the pruning tools and ensure the blades are sharp and the cuts are smooth.
2. After pruning,消毒 the wounds to prevent infection by pathogens.
3. After pruning, carefully care for the bougainvillea for a period, controlling watering and lighting. Do not fertilize and prevent the wounds from getting wet.
Origin and Growing Habits of Bougainvillea
Native to Brazil, bougainvillea is mainly distributed in countries such as China, Brazil, Peru, Argentina, Japan, and Zambia. Bougainvillea prefers moisture but dislikes waterlogging, tolerates high temperatures and drought, dislikes frost, enjoys fertile soil, and has a strong resistance to barren conditions. It can grow normally in slightly acidic or slightly alkaline soil. Loose, organic-rich soil is beneficial for growth and flowering. The optimal growing temperature for bougainvillea is 18-30°C. It will flower only when the temperature stabilizes above 15°C. Opened flowers can tolerate temperatures as low as 7-10°C, but will be damaged by temperatures below 3°C.
Bougainvillea requires at least 9 hours of sunlight per day. With sufficient sunlight, the plant grows well, producing more and brighter flowers with a longer blooming period. Insufficient sunlight can lead to leaf drop and withering. Controlling the plant's sunlight exposure to 8-9 hours per day will result in bud formation and flowering after 45 days. If bougainvillea is not exposed to sunlight or is exposed to weak sunlight for an extended period, it will delay or fail to flower.
