What to do if clivia leaves fall off
Clivia leaves fall off without warning is always worrying. This ornamental plant, known as the "gentleman among flowers", can actually avoid abnormal falling leaves through scientific maintenance. This article will systematically analyze the five common triggers and corresponding solutions to help you quickly diagnose plant diseases. Light regulation: The basic guarantee for leaf health, emergency treatment for strong light burns in summer, direct light exceeding 35 ° C at noon will form brown spots on the leaves, and continuous exposure will lead to abnormal stomatal closure. It is recommended to use a sunshade net to filter 30% of the light, or move to the east-facing sill to receive morning light. Winter fill light techniques ensure that light is scattered for more than 4 hours a day. When using a full-spectrum plant fill light, you need to maintain an irradiation distance of 50cm to avoid LED lamp beads directly contacting the leaves. Temperature management: Avoid sudden changes in the environment and high temperature warning mechanism. When the room temperature continues to exceed 28℃, you can place ice packs (at intervals of 20cm) around the plants or turn on circulation fans to keep the air flow rate at about 0.5 m/s. The humidity balance plan is combined with temperature adjustment. It is recommended to use an ultrasonic humidifier to maintain the air humidity of 60%. Water spraying on the leaves must be completed before sunrise to avoid sunburn caused by retention of water droplets. Fertilizer application: Precise nutrient supply fertilization cycle Control growth period Apply nitrogen, phosphorus and potassium balanced liquid fertilizer diluted 2000 times every 15 days, and stop fertilization during winter dormant period. Newly transplanted plants need to be slowed down for one month before applying fertilizer. During the fertilizer damage restoration process, fertilizer should be stopped immediately, roots should be irrigated with clear water three times continuously, damaged roots should be pruned, and new soil should be replaced after pruning, and EM bacterial agents should be applied to repair the soil environment. Water control: The key scientific watering rule for root maintenance is judged by the "pot weighing method": water is poured thoroughly when the weight of the pot soil is reduced by 1/3. Maintain soil moisture in spring and autumn, and watering time in summer should be 6-8 a.m. It is recommended to optimize the drainage system cultivation substrate according to the ratio of legus soil: pine needles: river sand =5:3:2, and a 3cm-thick ceramsite layer is laid on the bottom of the basin to ensure that excess water can seep out of the drainage holes within 10 seconds. Pest and insect pest control: Common diseases in the biological control system identify leaf blight that show water-stained spots at the beginning, and can be controlled with 50% carbendazim 800 times solution;(T-J) The disease is characterized by concentric ring spots, and requires the alternating use of mancozeb and azoxystrobin. Comprehensive pest management During the outbreak period of scale insects, yellow sticky insect boards were hung and 22% Thiacong·High Chlorofluoride Suspension Concentrate was sprayed. Red Spider recommends using matrine + orange peel essential oil for biological control.
By establishing a four-dimensional maintenance system of light-temperature-water, water-fertilizer-pests and diseases, and cooperating with a regular inspection mechanism, Clivia can not only avoid the problem of falling leaves, but also achieve the ornamental effect of blooming 2-3 times a year. It is recommended to take plant growth records every month, establish exclusive maintenance files, and adjust management plans in a timely manner.
