Cultivation methods and precautions for Brazilian keel
Among many indoor green plants, Brazilian keel is popular for its unique polygonal prism shape and strong vitality. This succulent plant native to South America not only purifies the air, but also becomes a highlight of space decoration because of its tall and straight figure. With the correct maintenance methods, even novices can allow this desert visitor to thrive in urban rooms. 1. Environmental control factors Temperature and light management As a typical tropical plant, Brazilian keel is most suitable for growing in an environment of 20-30℃. Special attention should be paid in winter. When the temperature is lower than 10℃, the plants should be moved indoors to the sun, and a fill light should be used to maintain the light if necessary. Appropriate shade is needed at noon in summer to avoid burning the epidermis by high temperatures above 35 ° C. The matrix formula is optimized by mixing sandy soil and humus soil in a ratio of 3:1, and adding a small amount of perlite to enhance air permeability. When changing pots every 2 years, bone meal can be added as base fertilizer to ensure healthy root development. 2. Water management skills Scientific watering cycle In spring and autumn, follow the principle of "seeing dry, seeing wet", and wait until the basin soil is completely dry before pouring it thoroughly. When there is a large amount of evaporation in summer, you can water it once a week with foliar spray. After entering the dormant period in winter, you can replenish water in a small amount every month. The key points of humidity control are to keep the ambient humidity between 40% and 60%. Too dry can easily cause red spiders. You can regularly wipe the stalks with a damp cloth. Pay attention to ventilation during the rainy season to avoid stagnant soil causing root rot. 3. Modeling maintenance plan Trim and styling method Carry out plastic pruning every spring, and use disinfected gardening scissors to remove lateral buds. Keep 3-5 main branches of the main trunk, and apply plant ash to the incision to prevent infection. Avoid water for 2 weeks after pruning. Pest and insect pest control regularly inspect the junction of stem and nodes, and immediately remove scale insects with alcohol cotton swabs when discovered. Spray garlic extract every month to prevent disease, which is environmentally friendly and effective.
Through systematic maintenance and management, Brazilian keel can maintain a healthy growth rate of 15-20cm per year. This low-maintenance green plant not only adds natural wildness to modern rooms, but its upward growth form also symbolizes tenacious vitality. It is recommended to use it with cement basins or pottery basins to create a simple and atmospheric indoor landscape.
