Are plum blossoms suitable for indoor cultivation
Plum blossoms that bloom proudly in cold winter are often regarded as a symbol of noble character. In recent years, more and more gardening enthusiasts have paid attention to whether plum blossoms can be cultivated indoors. Behind this seemingly simple question, it actually involves multiple considerations of plant growth habits and living environment. This article will systematically analyze the key points of indoor planting of plum blossoms and help you create a poetic home landscape. Light requirements and placement strategies for the three core elements of indoor maintenance of plum blossoms. As a typical positive plant, plum blossoms require at least 6 hours of direct light every day. It is recommended to choose a south-facing balcony or a bright area within 1 meter from the window for indoor cultivation. Full sunshine can be accepted in winter. If insufficient light will lead to excessive branches and hinder flower bud differentiation, you can use a plant fill light to replenish light for 2-3 hours a day. Precise control of temperature and humidity The ideal growth temperature should be controlled between 15-25 ° C. In winter, it takes more than 30 days to experience low temperature vernalization of 0-5 ° C to normally bloom. The air humidity of 40-60% can be maintained through an air conditioner or humidifier, and attention should be paid to avoid direct heating causing the soil to dry too quickly. Management key points during special periods during flowering periods It is recommended to move the plants to a well-ventilated outdoor environment for 2-3 weeks, which can not only extend the viewing period but also avoid pollen allergies. After flowering, shear back and apply more phosphorus and potassium fertilizer in time, and use ferrous sulfate irrigation once a month to keep the soil slightly acidic. The variety selection plan for advanced indoor plum flower maintenance techniques recommends choosing ornamental varieties with strong shade tolerance such as 'Gong Fen' and 'Green Calyx' to avoid planting plum varieties that require strong light. Dwarf grafted seedlings should be used for potted plants, and the plant height should be controlled at 60-80cm. The substrate ratio and pot changing period use a mixed substrate with a ratio of humus soil: river sand: vermiculite =5:3:2, and bone meal is added as the base fertilizer when pots are changed in spring every two years. Choose a purple sand basin or pottery basin with good air permeability, and the diameter should be 5 cm larger than the root ball. Solutions to common problems are aimed at yellowing of leaves, and it is necessary to check for inducements such as insufficient light, too much watering, or soil alkalization. Regularly use bamboo sticks to check the humidity of the pot soil, maintain the watering principle of "seeing dry, seeing wet", and cooperate with leaf spray to cool down and increase humidity in summer.
Through scientific environmental control, plum blossoms can fully show their graceful appearance indoors. Mastering key technologies such as light management, temperature and humidity control, and matching it with a reasonable maintenance rhythm, you can realize the elegant taste of life of "appreciating plum blossoms on the desk and seeing the world in every inch."
