The leaves of Ping An Tree are "wrinkled"
As a star variety in the household green plant industry, Ping 'an tree is deeply favored for its tall and straight plant type and shiny leaves. However, many flower lovers have found that carefully maintained Ping 'an trees often have shrinkage and wilting leaves. This state not only affects the ornamental value, but also indicates a health hazard to the plant. This article will analyze the underlying causes of leaf wilting from a professional perspective and provide highly operable solutions. Four core elements of safe tree maintenance Scientific water and light management 60% of leaf wilting results from improper water management. It is recommended to use the "dipping basin method" for watering: place the flower pot in a water container for 20 minutes, drain it after the soil absorbs sufficient water. In terms of lighting, light is guaranteed to be scattered for 4 hours a day in spring and autumn, and 50% of the light needs to be blocked in summer. Full sunshine can be accepted in winter, but direct cold winds need to be avoided. Substrate acid-base regulation Ping An tree is extremely sensitive to soil pH, with an ideal range of 5.5-6.5. pH paper can be tested every month. When the value is>7, it can be adjusted by pouring ferrous sulfate solution (ratio 1:1000). It is recommended to use a mixed substrate of peat soil + pine needle soil + perlite (5:3:2) to ensure water permeability and permeability. Temperature gradient management Winter maintenance requires establishing three-level protection: when the temperature is less than 15℃, move indoors; when the temperature is less than 10℃, apply insulation film; when the temperature is less than 5℃, heat compensation equipment needs to be activated. Pay special attention to controlling the temperature difference between day and night to within 8℃ to avoid "frostbite wilting." Damaged leaves should be trimmed in time, and the incision should be coated with plant ash to prevent infection. Systematic disease control of leaf blight is highly contagious, and the initial symptom is browning of leaf margins. Recommended biological control method: alternately spray allicin (3 cloves mashed in 500ml of water) and Bacillus subtilis (1 g in 1L of water) once a week for 3 consecutive weeks. At the same time, strengthen air circulation and keep the leaves dry.
By establishing a three-dimensional maintenance system of "detection-regulation-prevention" and cooperating with seasonal management strategies, Ping An trees can remain green all year round. It is recommended to conduct leaf microscopic examination every month to observe the stomatal status of the back leaves, and adjust the maintenance plan in time to make green plants truly a source of vitality for the home environment.
