How to raise the newly purchased bamboo crabapple
As an indoor leaf-viewing plant, Begonia japonica is popular for its unique striped leaves. However, many flower lovers often cause their fallen leaves to wither due to improper maintenance after purchasing. This article will systematically explain the scientific maintenance methods of newly purchased Begonia japonica from environmental adaptation to four-season management. Environmental adaptation and basic management During the transitional period of new seedlings, it is recommended to place the plants in a semi-shaded ventilated place to slow down the seedlings for 3-5 days to avoid direct light causing scorched leaf margins. Use an electronic scale weighing method to monitor the humidity of the basin soil, and use the dipping basin method to replenish water when the weight is reduced by 30%. Substrate improvement plan It is recommended to replace the original pot cultivation substrate with a mixed medium of humus soil: perlite =3:1, and add 5% bone meal to improve root vitality. Spray brassinolide after pot change to promote root development. Technical points for four-season maintenance: Light and temperature control. Ensure 4 hours of scattered light every day in spring and autumn, and use 75% sunshade net in summer. Maintain a constant temperature environment of 15-22℃ in winter, and start the heating equipment when it is below 10℃ to avoid the temperature difference between day and night exceeding 8℃. Precise management of water and fertilizer during the growth period, the "sandwich watering method" is used: after the surface layer of 2 cm is dried, water is poured in three times at intervals of 10 minutes. Combined with the application of nitrogen, phosphorus and potassium 20-20-20 water-soluble fertilizers, 0.1% ferrous sulfate solution is added every 15 days to prevent yellow leaves. The pest and disease control system rotates the use of mancozeb and azoxystrobin monthly to prevent leaf spot disease. During the high incidence period of red spiders, yellow sticky insect boards were set up and combined with azifenil spray for control. Regularly prune overly dense branches to maintain ventilation and light transmission. Special period management techniques Apply additional potassium dihydrogen phosphate solution (800-fold dilution) during flower bud differentiation period, and maintain air humidity at 60%-70% during flowering period. During the dormant period, control the watering frequency to once a month, stop fertilizing and reduce the light intensity.
Through scientific environmental control and refined management, Begonia japonica can remain ornamental throughout the year. It is recommended to establish a maintenance log to record temperature and humidity changes and plant growth response, and gradually master personalized maintenance plans.
