The Breeding Method and Precautions of蚌兰
In the urban balcony planting circle, the purple-backed perennial凭借 its unique leaf texture and easy maintenance characteristics is becoming a new popular green plant. This plant of the Commelina family, native to Mexico, not only has air purification capabilities but also its purple and red leaves have a filter effect. Master the following key points of maintenance, and you can also easily cultivate an ornamental plant with perfect condition.
Four Basic Elements of Maintenance
Soil Mixture Scheme
It is recommended to use the golden ratio of珍珠岩: decomposed leaf soil: coarse sand = 2:5:3. This structure can ensure drainage and is rich in organic matter. The potting soil needs to be changed every 2 years, and adding bone meal during spring potting can enhance root vitality.
Water Management Rhythm
In spring and autumn, maintain a watering interval of 3 days, and shorten it to 2 days in summer when evaporation is high. Using the immersion pot method to replenish water is safer, immediately removing when the water level reaches 1/3 of the pot height. Control water in winter to once every 10 days, slight leaf wrinkling is a normal phenomenon.
Temperature Control Strategy
Maintain an 18-28℃ growth golden range. In winter, it is necessary to take three layers of warming measures: pot-in-pot method + foam box padding + placement on a south-facing windowsill. Before the arrival of cold currents, spraying phosphorus and potassium can enhance cold resistance.
Light Balance Principle
Morning 2 hours of soft light is the best scheme, and sunshade netting is needed at noon to filter strong light. A north-facing windowsill can be placed all year round, and regularly rotating the pot 180° can make the plant shape more symmetrical.
Advanced Maintenance Techniques
Supplementing with chelated iron fertilizer once a month can enhance leaf color saturation, and spraying mancozeb during the plum rain season can prevent leaf spot disease. When pruning, retain 3-4 old leaves at the base, and the cut branches can be hydroponically cultivated for 15 days to obtain new seedlings.
By accurately controlling temperature, humidity, and light intensity, combined with a scientific fertilization scheme, it can achieve the effect of a full pot in about 6 months. It is recommended to use red pottery pots for planting, as their breathable characteristics perfectly match the plant's needs, and配合 hanging cultivation can better showcase the waterfall-like growth beauty.
