However, many novice flower lovers often encounter problems such as difficulty in flowering and scorched leaves during the maintenance process.

Key points for basic maintenance of Jianlan Golden Lotus: selection of pots, matching soil and pot replacement cycle Jianlan Golden Lotus root system likes to moisten and is afraid of waterlogging. It is recommended to use purple sand pots or plastic pots with more ventilation holes. The formula of plant materials can be used: pine bark (40%)+ volcanic rock (30%)+ phytolite (20%)+ organic fertilizer (10%). When changing pots every two years, 1/3 of the old plant materials are reserved to help serve the pots. Coordinated management of light and temperature requires 3-4 hours of morning light every day in spring and autumn. In summer, a double-layered sunshade net (shading rate of 70%) is used, and full sunshine can be accepted in winter. Maintaining the temperature difference between day and night at 8-12℃ is most conducive to flower bud differentiation, and the winter maintenance temperature should not be lower than 5℃. Accurately controlled water and fertilizer watering follows the principle of "moistening but not wetting". It is watered thoroughly in 5-7 days in spring and autumn, and sprayed in the morning and evening in summer to increase moisture. During the growth period, use nitrogen, phosphorus and potassium balanced fertilizers (20-20-20) and special organic liquid fertilizers for orchids alternately, and apply phosphorus and potassium fertilizers (10-30-20) during the bud pregnancy period. Advanced maintenance skills Scientific pruning method Keep 5cm of flower stems after flowers to be withered naturally, and cut off the yellow leaves at the base in time.

The key is to grasp the four-season maintenance rhythm of "promoting buds in spring, protecting seedlings in summer, promoting flowers in autumn, and storing energy in winter." It is recommended to establish a maintenance log to record temperature, humidity changes and growth status, and gradually form a personalized maintenance plan.
