How to water Cymbidium
As an aristocratic species in the orchid family, Cymbidium is favored by gardening enthusiasts for its elegant flower appearance. Mastering scientific watering methods directly affects the flowering quality and growth status of plants. This article will systematically analyze how to create an appropriate water management system through three dimensions: four-season maintenance points, advanced skills and common misunderstandings. 1. Rules for watering Cymbidium in four seasons 1. The water replenishment strategy during the spring period (March to May) will enter the rapid growth period when the average daily temperature rises to 15 ℃, and the substrate needs to be kept continuously moist. It is recommended to use a fine-perforated spray can to slowly pour it through along the edge of the basin every morning, and use it with noon leaf spray to maintain the air humidity above 60%. If new leaves are found to curl or false bulb folds, water must be replenished immediately by dipping pot method. 2. Summer high temperature management (June to August) During the high temperature period above 30 ℃, the "morning and dusk double pouring system" needs to be implemented: the first water penetration is completed from 6 to 8 o'clock, and the second water replenishment is carried out from 19 to 20 o'clock. Pay special attention to avoid transpiration burns caused by noon watering. You can place a water storage tray at the bottom of the flower pot to create a local humid environment. 3. Water control techniques for autumn flowering period (September to November) The flower arrow extraction period is adjusted to 3 days per time for quantitative watering, and extended to 5 days per time after the flower buds develop color. By stimulating flower bud differentiation through the "alternating drying and drying method", it is advisable to control the moisture content of the substrate at about 40%. Excessive wetting may easily lead to bud loss. 4. During winter dormancy maintenance (December to February), root activity decreases in low temperature environment. The principle of "seeing dry, seeing wet" is adopted, and watering is carried out at an interval of 2 days after the substrate is completely dried. The water temperature needs to be allowed to stand in advance to be consistent with room temperature. It is recommended to use spray instead of watering in severe cold weather. 2. Key points of advanced watering technology 1. The water quality pretreatment plan gives priority to collecting rainwater or using RO water purification. Tap water must be dried for 72 hours and added with citric acid to adjust the pH to 5.5 - 6.0. Rinse the substrate with diluted white vinegar water (1: 200) every month to prevent salinization. 2. In addition to regular watering, a three-dimensional water replenishing system should be built to build a three-dimensional system of "root water absorption + leaf moisture replenishment + environmental temperature control":·Plant material layer: Laying water moss/bark in layers to ensure water permeability·Air layer: configuring ultrasonic humidifier to maintain 60% humidity·Protective layer: Shade nets reduce transpiration rate in high temperature seasons 3. Analysis of typical maintenance misunderstandings 1. Avoid soaking in "waist water": Long-term water accumulation will cause fleshy roots to rot 2. Avoid sudden cooling and sudden heating: The temperature difference in water temperature in winter needs to be <3 ℃ 3. No spraying of buds during flowering period: residual water may cause gray mold 4. Prevention of stagnant water in the leaf core during the bud period: Cotton swabs can be used to absorb stagnant water in the bud core. By systematically mastering the seasonal watering rhythm and water quality management techniques, and cooperating with environmental control measures, Cymbidium can achieve three new buds extraction per year. Increase the flowering rate by more than 40%. It is recommended to use a moisture detector to monitor the EC value of the substrate every month and dynamically optimize the watering plan so that this noble orchid can show its glory to its fullest.
